Easy fellas. There are a few members here (including myself) that have spoken with Allen personally. He is a good guy and appears to have a quality product. We are currently working with him to try and establish a good relationship here. A few of us anticipate purchasing some of his manifolds within the coming months and will share our experiences with everyone. These could be a great option for many of us, as there are currently very few manufacturers of aftermarket marine exhaust manifolds for small block Fords.
Stay tuned! ------------- |

TRB, I too have spoken to Allen, one great guy.For sure we have 3 sets sold,2 SBF and 1 SBC,if i remember correctly for 1350 a pair.Allen told me if i order 7 pairs ,The Boat Doctor will be concidered a distributor and the price we pay will decrease.
All you guys look at his site and get back to me ..............boat dr He can build any shape or form GM/Ford/Buick/Mopar all we need is 7 to get the bulk price.......... ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

Doc, the 3 I know of are you, me and Reid- all SBF's I think. There was someone interested in a BBC, wasnt there? Not sure if he ever firmed up.
Are you still thinking March-April timeframe? You may want to touch base with Allen again. I have sent him a few emails but havent heard back- not sure if I have his newest address. Judging by his post, his fall slowdown may be starting in Australia. ------------- |

Jerry, SBF = Small Block Ford (and SBC = Small Block Chevy, BBC = Big Block Chevy). The 289/302 and 351w are small block Fords, so they'll fit.
Once nice thing about the manifolds is that they are one piece- which would replace both the cast iron manifold and riser. JR_VIC has them installed on his '92 Ski Nautique (PCM 351w):

boat doc, I want to check with Eric to see if he thinks they would fit under the motor box on the 454. I did manage to work so over time that I was not planning on getting. Do you think they would be a direct bolt of for me based on pics of my motor in the before eric thread? Being a BBC would the price change? ------------- |

87, they are a direct replacement for the PCM and the OSCO manifolds,the price is a little more than the 1387.00,how much don't know but will find out..........
todicus, Allen claims 30 HP, which would be about right,good headers will gain about 10%. The big advantage is the weight,SBF/SBC=12lbs. If i do the math that would reduce 100lbs.My Ex Wife spent 8500.00 for a tummy tuck that got rid of 10 lbs.Wonder how much a butt job would have cost,there was a 30lb.chunk there.

Todicus, we dont have a ton of info on the manifolds. JR_VIC posted his results with them in http://correctcraftfan.com/forum/forum_posts.asp?TID=4900 - this thread. They definitely sound promising! When I spoke to Allen a year ago, he a$$ured me that they are drop-in replacements for the PCM/Indmar manifolds. The Hiteks dont require any more space than the stockers. Boat Dr, thats great news. I missed Allens call yesterday, but Im glad to see he got through to you. If you need my info give me a call- I believe you have my number. I a$$ume the $1387 is for the bare manifolds (not polished or powdercoated)? Like I think I mentioned to you before, if I get any coating done, it will be something like jet-hot. ------------- |

79, you don't need to go back to school,it's my math that is suspect. Total weight of 2 manifolds is 62lbs.2 Risers weigh 42 lbs. this adds up to 104 lbs. subract 12 lbs per manifold and you only lose 80 lbs.

I thought they would weigh a little more too until I thru them on a scale myself a year or too ago . Have heard from more than one person switching from cast to aluminum saved about 100 lbs. By far the hy-tec's are the lightest available and are half the weight of the AL edlebrocks I'm installing. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

I have been very happy with the Hi-Tek headers so far. As mentioned in a previous thread they bolted up almost as easy as the OEM ones with the exception that the way the headers come out and turn up I was only able to get a socket on about half of the bolts but again I don't have a vast selection of specialty sockets etc. The remaining bolts had to be tightened with an end wrench and with about 10 hours of use none have losened up so far. Absolutely no clearance issues at all anywhere on my 92 SNCB. Did not have to adjust the carb settings with the exception raising the idle about 100 RPM. Took it to the lake and picked up 4.0 MPH. I have also added the new style DUI HEI style distibutor and a Weiand intake as well. Also changed to a rear billet metering block and upped the jet sizes and the boat is now running about 52.5 MPH with 14 degrees of timing which I have been very happy considering these are only bolt on mods. I mentioned to Boat Dr. that the last few times out I am still having the starboard side run hotter than the port side by about 70 degrees (140 port to 210 starboard) only at idle but seems to normlize under way. Hope this helps.

if you use socket head cap screws instead of hex head screws it's a lot easier to install without clearance issues but then again you need a special socket with an allen wrench too. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Boat Doc, I a$$ume youre including me in your SBF count. I do not want any paint or powder on them- Id prefer them bare. I plan to have them jet-hot coated once I get them.
Not sure if that changes the price or not. ------------- |

Boat doc will Allen back the fact that they will fit under the motor box with no mods to it on a BBC. I see they fit JR_VIC's Boat but I just want to be sure I wont have to make any changes when I get them.
JR_VIC did your motor actually idle slower once you put the hi-teks on? Why do you think one bank is running hotter then the other at idle? Is one getting less water then the other for some reason? Does anyone think that the one bank running hotter then the other at idle could casue any problems down the road. ------------- |
Posted By: 79nautique
Date Posted: February-15-2007 at 8:03pm

if that side is lean then it would run hotter and down the road would cause problems. The hy-tek's aren't causing the problem that's for sure. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

I thougt it may be the carb as well but I ran the boat the weekend before with the old manifolds and it was OK from what I recall. I remember checking the engine over as I had just changed the exhaust hoses out a few months before and I just don't remember there being any difference in temp. at that time. I did change the water pump/thermostat about the same time as the Hi-Teks so that may be the cause. I'll call DIM and talk to them.

sounds like a water flow problem, water takes its easiest path especially at idle, its possibly that there may be corrosion in the risers or some where else, fire the boat on the trailer and see if there is a difference at the exhaust in volume of water. if it was a carb or thermostat it would heat both sides and the problem disappears at wot, because now the water is under higher pressures and possibly is making its way through the restrticted area and allowing it to cool ------------- "the things you own will start to own you" |

Im not saying theres no corrosion, but I doubt there is any in the brand new one piece SS manifolds. ------------- |

Date Posted: February-16-2007 at 11:07am

depends on the quality of the exhaust too. If there is a difference in the jackets that create the water cavity so that one side can hold a large amount of water vs. the otherside then one would be hotter than the other. I would think they se a jig so that they are the same but I have never seen there manifacturing process and if they are all done by hand then you will see a difference from one to another and could create this very problem. Double check the routing and hose sizes for something to create a restriction on the side that is getting hotter. 5-10 degrees I wouldn't get excited about but 20-30 difference side to side isn't right. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Date Posted: February-16-2007 at 11:27am
| Some difference in mani temps is normal as far as I know. Looking at the Tstat housing it would appear that the easiest route for the water to flow is straight over to the port side manifold. It's probably just more noticeable with the stainless steel vs. the cast which will take longer to show swings in temp. Just a theory for conversation's sake. |

I will do a search again here in the forum but it seems as though I either read it here, talked to Vince at DIM, or one of the tech guys at PCM in North Carolina told me that it was normal to have the starboard side manifolds on my 92 351W to be hotter than the port side but not sure by how much. As M3Fan mentioned, it could have been doing this before but because I was never really paying attention to the stock manifolds it went unoticed. This may sound strange but the stock OEM heavy cast iron manifolds are very thick as most of you know and you don't hear much exhaust sound around the manifold when it is running. I say this because in the past if I was tuning the carb with the engine running on the trailer and bent down leaning over the engine with my ear close to the stock OEM manifold you don't hear much exhaust sound. After I changed to the Hi-Tek headers and in the same situation of bent down and leaning over the header to adjust the carb while the engine was running on the trailer, I noticed you could hear an exhaust note at the header...not a ticking exhaust leak just an exhaust note. As I leaned my ear right up almost touching the header you can hear alot of exhaust sound unlike before. Don't get me wrong, it is nothing that is real loud and you would not notice with the engine cover closed because in that sitaution it sounds just like stock. My point is that if I leaned over to the header very close you can hear so much more exhaust sound than before leading me to beleive that the walls surrouding the headers appear to be very high quality yet much thinner than the stock, thick, cast iron manifolds. Make sense? If you lay your hand on the side if the headers you can almost slightly feel the exhaust pulses. Maybe because of this design you just can hear a little more and you also feel more tempature as well. One other note...the engine temp is perfect and running a touch cooler than before and when I ran my hand over the water spitting out the rear of the boat while idling on the trailer it does not seem any hotter than before. Also...most of this higher temp on the starboard side is behind the header at the rubber exhaust hose that connects it to the muffler and not so much on the header itself. Any more ideas? ------------- "That's not a Snow Cone that's my Ring!" |

Yes they have drain plugs...one on each side. The boat in the water sounds just like it did before with the stock OEM manifolds...no difference in sound in my opinion.

Boat dr...good talking with you the other day. Alan called me but I missed his call and have not had a chance to call him back but I will next week. When I get to work he is asleep and when I am leaving work he is waking up but I'll catch up with him.
Update...I spoke with Karen Dougherty (Vince's Wife) at DIM today about my header sitaution and the starboard side being hotter than the other. She first told me to contact Vince on Monday but she told me that about 6 months ago she and Vince were on a call with PCM about installing a PSS shaft seal on a Ski Nautique 351W in which you add a water line that bleeds off of the main water line that supplies water to the exhaust manifolds. PCM told them to only tap into the water line going to the exhaust manifolds on the Port side of the engine because there is more water supply on that side of the engine due to the way it is designed. PCM stated there is less water on the Starboard side already so if you tap into that water line going to the exhaust manifold you will make the starboard side even hotter. I found that to be very interesting. She told me to contact Vince next week as he may have more details but it sure sounds like what she said could be fact because that is what my engine is doing. It sure seems like I have heard this same thing before along time ago but I can't remember where I heard it. Talk to you soon. Thanks! ------------- "That's not a Snow Cone that's my Ring!" |

I am also using the PSS shaft seal. Here is a link below to the install instructions for the PSS shaft seal from elberts website and look on the first page at number 11. The instructions say tap into the Port side exhaust riser hose although they don't say why you shouold use the Port side and not the Starboard side.

87 ; a note from Allens BOSS Billy,
We do not send our manifolds away to our customers NOT powder coated or polished as we did that once as the customer wanted to polish them his self and he showed his friends before he had them polished which Allen had told him not to as Allen has to flapped disc the manifolds specially to get the manifolds polished, so we now have this policy of either powder coated or polished. Hope this answers your question. Looking forward to hearing from you. Regards, Carolyn: Talked to Allen again tonite,he says the same,the port side seems to flow more than starboard,his fix,add a restriction to the port hose,on his boat he used a S/S "nut" to solve the problem,any thing to slow down or balance the two....... ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

Doc, I guess Ill have to speak to Allen directly. If they dont offer jet-hot coating, then I definitely want them bare. Theres no sense in having them powdercoated since I would just be stripping it off (at an extra cost). No sense in polishing either, since the jet-hot will just cover it up.
Not sure if you guys are familiar with jet-hot or not. Its a metallic-ceramic coating commonly used on headers. Its good up to 1300 degrees, and shines like chrome.  ------------- |

TRB just spoke with Boat Doc less then half hour ago. He said Allen would rather lose a sale then send his product out unfinished. In order for him to let it leave the shop to a customer it must be polished or powder coated. He said he had a problem leting a set leave, the guy never had them finished or something and they look like hell, well that's what he told boat doc anyway. So maybe speaking will Allen about him jet-hotting them for you would help. ------------- |

87, thats what I was afraid of. I just sent Allen/Carolyn an email, so hopefully we can work something out. I have a great local guy who does all sorts of coatings (powder, jet-hot, etc) that I would love to do the work, as his work is very good and is reasonably priced. I supposed if Hi-Tek can get them coated before sending them, that would be an acceptable solution.
Although I can understand their position, it doesnt make sense to incur the extra expense of PC, since it will only cost me extra to have it stripped. ------------- |

they are worried that if they send their porduct out unfinished and you don't have it finished(which I am not say you would do this) then their product and name is on your boat someone askes where you got the manifolds and you tell them. That other guys says those things look like hell no way would I buy a set from those people. When all the problem was is the customer never had them finished like he said he was going to.
I talked with boat doc about this and we both see Allen's point of view on sending out an unfinished product. We know your going to have it finished but he has already run into the problem with a guy not getting them finished. Someone tells you stick your hand in a snake cage he don't bite, you do it and you get bit. You have a hard time sticking your hand in that cage again no matter how much someone says it don't bite. Just my two cents on it. I was hoping to get them bare myself, but it's just not going to happen. ------------- |

87, I understand their position. Hopefully Hi-tek will understand that I dont want them bare because Im being cheap. These manifolds are very expensive, and I want the best coating for them- Im not convinced powder is the way to go.
It seems silly to pay extra for the powder since it will only be removed when I get them. Ill get them bare either way! Again, perhaps Hi-tek can get them Jet-hot coated for me at a reasonable price. That could be a good solution for everyone. ------------- |

why not get the polished? if they are made from a quality grade of Stainless steel they won't rust and always look good, now if he is using 303 then your screwed. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

79, Ive got a call in to my coating guy, but I am hoping that the Jet-hot would cost about the same as powder would. The polished finish is a additional cost ($300) from Hi-Tek.
With the Jet-hot, I think I would be safer from heat discoloration, rust and corrosion than either the polished or powder finishes. Im not sure what grade of stainless Hi-Tek uses. It does say on their website that manifolds are bead blasted to prevent rusting at the welds. ------------- |

bead blasting is going to do sh*t to prevent rusting, just remove surface rust if there is any. These are not going to get hot enough to discolor and if they are made form a quality grade like 304 or 316 and pa$$ivated after they are made then it won't rust or corroid and would only require polishing once awhile to keep the shine. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

I pushed Alan to have them shipped uncoated as well and he would not do it. I could not cover the $300 for polished at the time so I went powdercoated. The first two-three inches of the header where it is not jacketed will just melt off but no big deal to me. You don't really notice them unless you bend over and look at it. I may take them off and try to polish just the header part and see if how it comes out. Hope that helps...
Thanks! ------------- "That's not a Snow Cone that's my Ring!" |

This is the area where I was concerned about discoloration on a bare (polished) manifold. I also dont think that jet-hot would burn off, unlike the powder. Agreed, 79- not sure what grade of stainless Hi-Tek uses. Optimally, I would like to have the headers coated with jet hot for about the same price as Allen wants to sell the powder versions for. They should be more durable and slightly less expensive than the polished version. ------------- |

the only thing about jet-hot coating is it has to be on the outside and inside for it to work right. With the jacket it might not coat the runners very well and cause problems. With headers it's not that big of a deal but with the jacket it might trap an air pocket when they dip them and not coat inside the jacketed area as well as it needs to be. Guess if the person dipping it rotated while in the tank to makesure all of the air is out then it should be ok. diffently couldn't just drop then in the tank along because air would get traped unless it was under vaccum in a pressure vessel. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Thanks for the info, 79- that sheds some light on the jet-hot process. I sent my coating guy a picture of the Hi-teks and will call him to discuss. Hopefully this is something that Allen can have done locally if he wont ship them bare. It doesnt make sense to pay extra for powder or polished if Im going Jet-hot anyways. ------------- |

he's out sorcing the polishing and coating anyway wouldn't see why he couldn't have then jet-hot coated might be a little more after shipping cost are added, then your at the polished price anyway so you might as well buy them polished, your spending 1400.00 already what's another 300.00 for the marginal increase in performance. Once I looked at the comparison on their website, the gains don't kick in until the higher RPM range anyway and there's very little difference from idle to 3500 rpm which is the range you'll run the most. Again they look great but to me not worth the cash layout. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Im hoping he can do the Jet-hot coating instead of the powder for a similar price. I dont see the sense in going polished unless 1)Allen cant do the jet-hot and 2)stripping the powder would cost more than $300.
Your argument for polished makes sense if I wasnt jet-hot coating them, though. As for performance, I get an instant 3200 RPM out of the hole so I should see some gain there. We do plenty of skiing and barefooting at higher RPM to make the difference worth it (I hope). Youre right though, they sure arent cheap. Thats why Im trying to put the best finish on them right from the start. ------------- |

I was getting a solid 3000 with my Acme prop and stock motor. Remember, I have the 1.23 tranny. Anyone else with a 1.23 want to back me up? ------------- |

Mark, make sure you put your hair in a ponytail so I can look back thru my mirror and still see around you to see them. I'll bet if jbear tried to pull his hair back, he'd have to use a bungy cord. I'm gonna grow a skullet. Similar to the mullet, but only with no hair on top and long hair all around, i.e,. Hulk Hogan. I reak of jealosy.
I'm putting a power glide in my next boat. Gear heads and old guys know what that is. Heck '79, you of all people know that the instaneous slip of the prop is about as close as you could get to simulating a stall converter, but even better without the sudden bang. It's also what allows a boat to run some extra cam without demonstrating the typical low-end torque loss seen in a car and necessitating lower gear ratios. I'm still studying the holeshot and speed issues of the 1.23 vs 1:1. ------------- ReidP /diaries/details.asp?ID=231&yrstart=1971&yrend=1975 - 1973 Mustang |

Reid; I still don't understand a word of what you guys are talkin' about with this slip and stall and lowend stuff but I sure do like the sound of it.

I can only add that my boat does similar, instant 2.9-3k when I nail it to rabbit, it launches hard and holds that rpm to somewhere between 17-20 mph then seems to grab more firmly as rpms climb from there with speed more linearly. mine is 1:1; Its done that since I put the OJ 4 on it. Doesn't do it with the federal, POS acme I tried, nor so much with the OJ-3.
Engine goes straight to the torque peak and when it grabsfirm, the boat just slings out of the hole like a banshee instead of the rpms dropping when the slip fades. Engine is nothing special (yet) other than a good state of tune, hot ignition and mapped advance curve. I suspect the 1.23 is a superior, more efficient system because of the lower tip speed, potentially less parasytic losses above 40 mph. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing."

I guess If I used the smaller pitched prop it would do it more but mine just goes no lag just nice and steady pull.
The powerglide tranny's are great racers love them the're pretty much bullet proof. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Like I said, I put on a new fuel pump and a K&N, I dont know which one did it, but it made it much faster in the midrange, not much at the top if any at all, it picked about 100rpm!
If jbears boat goes 50mph, I still dont think that will move his hair...

each piece a chrome is worth 5 hp so some people say. it's not true but it sounds good. Some people joke motors are like women, treat them good, dress them up well, and they will preform like wild fire. ------------- |
