hi,
i have a question for all you experts.. i am finished with my 351 w motor, reman short block, new gt40p heads. i now need a distributor. i was going to convert my prestolite points set up, but it was hammered. so my question is... do i get another points prestolite, and use the conversion kit i already bought, or buy a converted prestolite , or mallory, msd, or dui, or??? my engine is a non auto rotation, and it is going in my fish nautique |

How big is your wallet? The DUI seems to be the distributor of choice for many performance enthusiusts here. Of course there are a few that prefer the mallory. If you buy a new Prestolite points distributor and then convert it you'll have almost as much in that distributor as a new DUI or Mallory. As of now an MSD is not an option as they do not currently produce a marine distributor for the 351W. ------------- 95 Malibu Echelon w/Mercruiser 350 Magnum Skier Former boats: 88 Ski Centurion Tru Trac II 59 Chris Craft Capri (woody) |

i have the prestolite conversion i was going to use on my old dist. i can return it though and buy whatever. at this point i am so deep into my wallet, whats another couple hun....
my concerns are reliability, (are parts available if i am down in baja somewhere) fuel economy as it is used for a offshore fishing boat, and of course performance differences. thx for any feedback, i need to pull the trigger on this as it is my last need chris |

The DUI can use off-the-shelf GM HEI replacement parts (coil, cap, rotor, ign module). They wont perform as well as the DUI equivalents, but they will get you up and running. A hotter spark and consistent curve can only help efficiency and performance, and I think the DUI is better than the rest. ------------- |

i called dui, they said due to my engine being reverse rotation, if my old distributor gear is 530 thousands, they have a unit i can use with my old gear.
other sources tell me the internals are different due to the advance, and possibly oiling grooves of the shaft because the distributor also is oposite rotation. my question now is, does a reverse rotation engines distributor turn the same direction as a standard rotation engine? if so i can get this project going alot sooner as a standard rotation dist. is easy to come by and cheap, and i will just swap out my old gear thanks, chris |

Yes it turns the same direction no matter what rotation the engine is, the gear on the bottom is different on each unit though. I just got my new Mallory Magnetic dist yesterday and will be putting it in this weekend. I like the DUI and I've heard they perform well but it just doesn't look right on my Ford. Mallory guarantees me the gear off my Prestolite will go right on their Ei unit. Their RR dist was backordered for another month so I purchased the LH unit and I'll swap gears, also saved about $50 doing it that way. ------------- You can’t change the wind but you can adjust your sails |

thanks alan,
so is the distributor you are using a ylm554cv or is it a ylu554cv? my understanding is the ylm series is more resistant to power spikes and the option i want to go with. i also tried to order the ylm554dv, but was told 1 month waiting time thru my supplier. please let me know if your old gear works, and i will go the same way if it does. chris |

don't buy the the thing from JEGGS you'll never get it, order it from sumitt racing and you will get it quickly.
Lot of hype about the DUI unit, it's over rated, get a curve kit and adjust the dist likes it needs to be and the mallory YLU unit will out perform the DUI every time. So if any one else once to chime in go a head, just know what your talking about because I do know this subject quite well. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

I got the YLM, the tech at Mallory liked the YLU because they are easier to troubleshoot should it ever give you any problems. The YLU is a little more money .
79, I tried Jegs and Summit and also searched all over the web. Found a few places that the DV in stock but they must have been gold plated or something so I ordered from Summit, Supposedly one week backorder but the date kept changing until late sept now. Screw it, ordered the CV and I'll swap the gear. ------------- You can’t change the wind but you can adjust your sails |

Allan I had the YLU unit and got the same run around at jegs, and called summit after a couple months, talked directly to a Mallory Distribution Center top dog about it and knew it was availible, he even confirm the order from JEG's but couldn't say weather it was mine or not.
FYI, Mallory has a new numbering system so it's like a 9xxxxxx something number now might give that a shot. Might try Mallory marine's web site for the right number. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

That's the right one Tom but too rich for my blood. $255 for LH from Summit, good deal if the gear interchanges like it's supposed to. We'll see how that work's out.

did you remove the roll pin first or just shear it off because you didn't know any better? Allen take a small straight punch and drive out the roll/spring pin just enough to clear the shaft but not all of the way out, much easier to re-assemble if it's not completely driven out of the gear. But once the poll pin is driven back the gear will slide right off pretty easily as they are designed with a slip fit and not a press fit. Also there should be a small pimple somewhere on the gear this should line up with the tip of the rotor. Shouldn't be any issues doing it at the lake. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

79, i might be a newbie, but i am not a dipsh&^
i have wrenched all my life in some way or another, usually motorcycles. my old distributor was in rough shape, and the gear was definately tight on the shaft. in the past and in this case, i find that using a nail with the head cut off works very well for roll pins if you dont have the correct diameter punch. i had to use a puller to get my gear off. one other concern, my old shaft has a spiriled groove around the shaft. it is directional, is that to keep the oil from traveling up the shaft?

Date Posted: September-05-2007 at 1:27pm
Actually did it last night Chris. Roll pin out with a punch and I did use a small gear puller to get the gear off. Only thing different is you need to drill out the roll pin hole in the gear as the hole in the Mallory dist shaft is larger. The Mallory tech told me I would have to do this. It did go back together pretty easy but I noticed the hex drive on the bottom of the shaft lines up differently than the stock so I had to mess with the oil pump shaft alignment to get it to drop back in. ------------- You can’t change the wind but you can adjust your sails |

79, I'm curious why you say the mallory out performs the HEI. I know that you have designed ignition systems and know your way around the electronics, so I want to know your reasoning. I went with the HEI because I'm a GM nut and I know that dist. I did do some custom curving to get it where I want it, but it performs flawlessly.

the YLU unit has a optical trigger, the YLM and HEI have magnetic triggers. What's faster, light or a magnetic field? which is more stable, which has a more consistant trigger pattern (firing of the spark plugs)
the mallory promasters series coil has a higher output than the DUI unit as well. and for all you that want to say well if there's water on the lens or moister in the cap then the optical system fails or doesn't fire, well that's just not the case, besides if you have that much moister in the cap then you have other issues all together. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

So the YLU is like the Unilite series for autos? Understood now, makes much sense. My coil is 50 or 60,000 volts, I will check when I get home. What kind of coil do you run with that? I know I have seen alot of discussions on here about what coil, ballast resistor/no ballast resistor etc. It gets me confused. Also, is it a 3 wire hookup?

three wire pos, neg to the coil and a ground to the block. The DUI site list the coil as 50Kv unit vs 55Kv for the Mallory promasters series coils. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

So the Mallory has a hotter spark- what about duration? Thats what PerformanceDistributors is citing for their .055" recommended plug gap. Whats the recommended gap on the Mallory? ------------- |
Posted By: 79nautique
Date Posted: September-05-2007 at 5:11pm
Timmy Timmy Timmy you really bought that line of BS, the only way to increase the duration is to use a wide rotor segment, you are able to open up the gap because of the high Kv rating of the coil not because of the module. Besides the only reason to open up the gap is fuel milage not performance. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |
Posted By: TRBenj
Date Posted: September-05-2007 at 6:17pm
Agreed. That isnt to say that a longer duration spark isnt better though, is it?
Hmmm, you'll have to convice me on that one. My logic says that a hotter/stronger and longer (duration) spark will better ignite a lean mixture and provide a more complete burn- which would improve both economy/efficiency and performance. ------------- |

since i am a pin shearing dips*&^, and you obviously know your stuff, can you help me? i just locally found and ordered the ylu distributor, do i need some kind of recurve kit, and if so what is involved in recurving? and what promaster coil i should go with? i was on the summit site and got overwhelmed with options. i do agree though, thruout this project, summit has shipped the quickest |

efficiency = lean mixture = hotter engine temp = less fuel used = lower rpms performance = rich mixture = cooler engine temp = more gas used = high rpm = give me F'n fuel because I's got no time to be efficent and burn it all anyway so make it a double shot of High Octane please and I'll see ya later 
Like I said earlier the duration will not change due to the gap being increased. What you want is for the plug to fire a second time while on TDC and that is what the MSD and Mallory spark boxes do won't help abit on fuel milage maybe a 1-2% better maybe. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |
Posted By: TRBenj
Date Posted: September-05-2007 at 8:25pm
Now I know we disagree 
Your description of rich vs. lean may have some degree of truth to it, but it certainly does not tell the whole story. Did I mention that I dropped 4/8 jet sizes (front/rear) and picked up 200 RPM this year? That tells me there is such a thing as TOO rich. I couldnt find the quote, but I believe Gottaski said something about achieving the best performance by being just a tad richer than "too lean." I agree that the a larger plug gap does not equate to a longer duration spark. However, it seems reasonable to me that the longer spark duration of the DUI (due to the cap and rotor design) does contribute to a more complete burn. The larger plug gap that can be run with the DUI probably has more to do with the higher output coil. ------------- |

hate to tell you that DUI unit isn't any different than any other stock HEI dist from the 70's-80's module included, might use a module from a corvette motor set-up but that's about it. And again you can run .055 or even .065 with the DUI, Stock HEI or Mallory like I had on mine. Your not getting anything fancy Tim just because they can copy/use an expired GM patent and parts, doesn't mean sh*t ran .065" gapped plugs in my '77 regal with a stock 350 and HEI dist. Hell tuned up a ton of cars at the shop the same .065" gapped plug and not a single one was a hot rod by a mile. Please quit trying to justify that the DUI is superior it's not, I can go to the fucjing junkyard and pick-up a cadilac HEI unit(or which which ever casting matches up with the ford) and get it to perform just as good as the DUI unit piece of cake extremely simple to do. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

79, you do have to admit that some of what you said is exactly a reason to use it. It really hasn't changed alot since the late sixties when it was introduced.

no problem, he just needs to get a conversion kit or a new dist.
After a season on the points they need re-gapped (dwell set) and re-timed as well as they are now a little worn. The HEI is a good unit but it doesn't belong on a ford motor and with the Mallory it looks stock, is easier to re-curve for any cam/engine combination and has better performance overall and cost less so to me it's a no brainer, Mallory you can buy into all the marketing BS if you want but facts are facts, optical trigger, stock look, higher Kv output, easier to adjust. So what if it has one more wire big deal. Oh what is that BS that just came out of your mouth Tim the DUI is only one wire, well not exactly, postive lead and a negative lead, what there isn't a neg lead on the DUI then what the f**k is that second wire for, oh the Tach you say, and what the f**k is that, a second lead that grounds the unit my friend. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

I guess you may be right on the Mallory/HEI argument (looks stock), but I really don't know why it's easier to recurve. It's just the HEI just comes naturally to me. You know, because I'm used to working on motors with REAL power. Just a little banter to tick off all you Ford guys.

well on the mallory unit the base plate inside of the unit is adjustable and limits the maximun possible advance, then it just comes down to selecting the right combination of springs to curve it. Where on the HEI usually you have to change the weights and springs and cannot limit the max advance so as the springs wear and loose some of there tenson the advance creeps up as well. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

I see your point on the Mallory, but not so much on the HEI. You can limit the advance with bushings that you put on the posts. As for the weights, you can grind on them til you get the curve you want, and play with springs. I did some grinding on the 'dog-leg' of the weights to give me more advance (I wasn't getting enough). ------------- Every day above ground is a Good day. Lakeland, FL |

I didnt claim it was a new design- but if it works, it works. Im unaware of any other HEI marine distributor made to work on Fords. Its true that standard GM HEI parts will drop right in, but the DUI module is better than the run-of-the-mill stuff you get at Autozone (I lost 200 RPM when I tried the cheap module).
I think the DUI looks good on my motor, but to each their own. Both the Mallory and DUI can be recurved, but if you say the Mallory is easier Ill believe you. Id be curious to see if there was a performance difference between the 2- I havent seen that documented yet. I do know that I gained 200 RPM on a stock motor by going to the DUI, so that sold me. As for price, the $375 would have bought me either the DUI or the Unilite and a new coil, so it was basically a wash.
Last time I checked, the tach signal wasnt a simple ground. By losing a few wires and the remote mounted coil, the DUI looks cleaner to me- but I certainly wouldnt call the stock set up messy. If I already had a good coil and plug wires, I wouldnt hesitate to go with the magnetic Mallory on a future project. ------------- |

Tim, The DUI on your boat does not look out of place at all, in fact in looks darn good sitting in there. My older boat I didn't think it would look correct. Price wise you are correct and I gave it the same consideration. As part of my rebuild this spring I installed a brand new coil for the EI conversion and a nice set of Plugs wires. I couldn't justify the expense of replacing those components. I believe both systems are more than adequate and it comes down to the specific application and personal preference. ------------- You can’t change the wind but you can adjust your sails |

you don't remember where I had mine mounted at? used that very same coil, made a bracket out of 404 stainless steel, used two of the intake bolts to mount the bracket it was pretty easy to do. And Tim why are you buying cheap ass sh*t from Autozone, get a Delco module and you won't see any difference, also take a look around the base of your dist, the machined OD section that the cap sits on and I bet you find a stamped 7-8 digit part number on. Do you really think they had a special casting made to work on the ford block. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

No I wouldn't suggest you do it, might not work after your done with it anyway, but Me personelly I could, but I do have an advantage since I worked for them and know how to run a lathe or machining center as well.
My point is there are already base housing out there that can easily be machined a little or are an exact fit all ready that would work. Perf Dist isn't doing anything fancy other than marketing, and are using off the self items to build the dist. they sold you. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

MM, I prefer the Zephyrhills brand myself, you know, keep it local. That's funny.
79, about the casting of the HEI. It is not a GM casting. I believe the castings for these Ford HEI distributors are coming out of Austrailia. They are really good castings too. I think that ProComp is making them...I bet DUI is buying blank castings from them and building theirs. ------------- Every day above ground is a Good day. Lakeland, FL |

I love a cat fight , when it don't include me even better.
I think this is a mute point to say the least, when you light off the fuel charge and it slowly moves across the piston, it don't care about 3 or 4 extra sparkies. British Thermal Units, determines horsepower, the more heat the more HP.Right up to the time when Mr. Squeeky Calls.Ask John Force,record setting runs are followed by a engine swap,smoked pistons bla bla bla. Dumping more fuel and sparking it more don't do it.........boat dr ------------- boat dr /diaries/details.asp?ID=4631 - 1949 Dart /diaries/details.asp?ID=1533 - 1964 American Skier |

since my boat is strictly in saltwater, and my history is with salt water boats, fresh water cooling is the term used locally. but, yes, i am putting antifreeze, heat exchanger, etc in my baby. saltwater will still be in the manifolds though. i have been looking at those hi tek stainless manis, but, they probably cost more than my boat. they look fabulous and i bet flow much better than the cast iron osco pigs.
anyone know the cost of the hiteks? |

has anyone tried the marine distributors that pertronix makes?
200 dollars, and already converted to their elecronic ignition. I can provide a link if you need, but I saw these on Summits website.... ------------- 78 martinique- refloored, reinforced, stringers re glassed, re engineered interior GT40P heads Edelbrock Performer intake acme 4 blade http://img.photobucket.com/albums/v64/horkn/fish/nautique.jpg |

Looks like I'm going to have to order a curve kit for the Mallory. Still only getting 28 total advance with my base at 12 before. Slowed my boat down and I lost 300 rpm on the top. Might rethink this and ask santa for a DUI after all. ------------- You can’t change the wind but you can adjust your sails |

i contacted pertronix, they did not offer my application.
reverse 351w, alan, i bet 79 can offer advice on your mallory, sucks to spend that money for a downgrade in performance, did you replace the coil as well? |
Posted By: 81nautique

The coil is the one DIM sells for their EI conversion and the boat runs 51 mph with the old EI conversion kit in it. I planned on upgrading the coil later and I didn't expect to really pick up anything without replacing the coil but I really didn't expect to go backwards either. I think it's just going to take some tuning with springs. ------------- You can’t change the wind but you can adjust your sails |

You don't really need springs yet, you need to open the stops to increase the final. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

Makes sense, I wish the darn thing came with some kind of instructions on adjustment. There's more info on the web than comes with it. Could have done some tinkering with it at the campgrounds if it had. Looks like I'll have to do a little reading tonight.

A little light reading, Thanks Tom for always pointing me in the right direction.

don't need the gauges just mark it with a sharpie and do a little trial and error. Believe you just need to close the ap a little. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

Allan if you have a dial caliber then you could use that by locking it down at a set distance, and using the side you would for an inside diameter should work just as good as the stick gauge in the curve kit. ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=756&sort=&pagenum=1&yrstart=1979&yrend=1979 - 79 nautique |

If you gotta miss C/C day I guess Key West is the place to be.
Wouldn't mind seeing you before you head back north. You guys can come over this way and we'll get Eddie and MM's Orlando gang together for dinner or something. john ------------- "Loud pipes save lives" AdamT sez "I'm Canadian and a beaver lover myself"... |

Played with the Advance today and had no luck. My YLM looks nothing like the diagram in the link above. There are no "arms" to control advance stop. There are 2 allen type screws that look like they would control the total advance by adjusting the bottom plate but it is already adjusted to the max.
Think I'll take a picure of the mechanism and see what you guys suggest. I can't find anything on the Mallory site about setting total advance except the pdf above and that must be for an older model dis. So for now I'm stuck with about 18 degrees of advance. I've got my initial set real high just so I can get more total but I know it's not right. I'll listen for ping tommorrow and see how it runs. ------------- You can’t change the wind but you can adjust your sails |

Well, starting to make some sense of this advance now. My distributor is clearly marked on the side YLM, this first picture is of a YLM
This next picture is of a YHM advance set up which is clearly what I have. 
Maybe I got caught up in a design/model number change but it sure has been a pain to figure out what the heck I've got here. May get a chance to play with this over the weekend. ------------- You can’t change the wind but you can adjust your sails |
