And so it begins...

I think Paul mentioned that i went above and beyond, fck if he said throw on a Vortech supercharger, here's the money...I wouldve. but going back he did come to me and said i got these great heads this and that i can you put them on and i said yes....but again it was my suggestion that since it was out i could pull the bottem down since we need to handle all that HP those heads will put out, I'll do the carb and give you a good qaulity turn key engine that all you will have to do is drop it in.
I ran my 400.00 bore gauge thru it and they were on the money, I couldnt use my eye cause i aint that good yet. re-bearing it, re-ringed oil pump and timing set.
now that would pretty senseless to slap on these fire breathing heads if the bottem was weak? I would hope you agree.
we both talked to scott and let him know exactly what parts we had and down to every detail. we didnt shoot from the hip, i gave him the head specs and so did paul and thats the cam we ended with. and my follow up call was going to the .500 lift may give you 2 miles per hour but the holeshot will suffer "with those heads"
Now,
sometimes you really fckin baffle me.
its a good strong engine, the rings need to seat and a few other things need to be dialed in, he did a couple runs on the weekend
and there are many suggestions from these guys and you are the reaper and in a way it seems like your trying to cover your ass because maybe those heads arent what they are cracked up to be

lol, if your happy I'm happy.
imagine buying 6 larger turbos to get 1 mile an hour..that's the point your at
really though send your to kid to college and go run your boat, now if you want to break out your communion money you have tucked away........

In terms of cams, I will say that I am not overly impressed with the Cam Research stuff I have seen, at least for pure high end performance. Not that the cams aren't great and that it isn't a great and necessary source for Reverse rotation stuff, but IMHO they error on the very conservative side when they hear ski boat and as a result the cams fall flat pretty quick on the high end. A lot of that is also limited by the manifolds we are choosing here, and yes it is a ski boat and first and foremost it needs a stout hole shot... but my various builds so far have never resulted in an engine that had a great top end but no holeshot. However I have built a couple that had pretty good holeshot and fell flat on thier face, and those were the ones where I was worried IMHO too much about the low end torque. The engines that have been/are great high end runners are also much more than stock out of the hole and they have much more agressive cams than I or others I have talked to had recommended by CR.

Again this all only applies to those of you with the particular sickness that drives a man to make his ski boat into a race boat in his own mind...

I also don't think there is a cam in the world that would get that boat to a legit 50 with those parts.. just too slow of a hull I think you would need a legit 325 hp and a great and well matched prop to even think about 50.

the other part and it's hard to tell in the pictures, put it looks like a stock intake is being used as well. And if the heads are not ported and using a stock intake and a stock cam, your not going to get much improvement, and then add all the other short cuts that where taken, it sure sounds like a brunstucky price and effort, take the money and run and who cares I got paid and did only what was asked and nothing more. I just concider the source and wonder why, expected it to a degree once I found out who the engine guy was. I never suggested any cam or stated any speed, only stated the valve specs, spring lift rating and that they need ported and provided the gauge to figure out the correct pushrod that was eyeballed and isn't correct, don't see how in the hell you can visually see where the middle of the cam lobe is so you can visually see the center of the valve stem, so I suppect that when the valve is closed it's centered and in actuallity it shouldn't be since it should be off center slightly at that point. SO it must be the parts since the mechanic picked the right cam, went the cheap route on the bottom end, cheaped on the the cylinder walls, and a bunch of other stuff, It just reminds me of the piss poor stringer job so now we have another to add to the many stories why it's the customers fault, seems to be a common practice of passing the buck.

Chris has implied that the heads in question have the small chambers (~58cc?), which would put the CR on the north side of 9. Your 302 had P heads, Joe?

I know when Dad slapped a set of GT40's on his '92, he picked up a decent amount of RPM and speed- that was reusing the stock cam and intake. Maybe these (presumably lightly worked) DO0E heads just arent all theyre cracked up to be.

Either way, I would think that a slightly better set of heads combined with a slightly better cam would still net more than a 1mph increase, especially when being installed on top of a new (read: lighter) structure. Maybe it is a tuning issue.

your not going to be able to use that extra compression when it's blowing past the rings due to not touching the cylinder walls and adding new rings only and that will never seat properly and seal like they should if the block was machined and the bores honed to allow for the rings to seat and mate with the cylinder walls.

I would be keeping an eye on the oil, and keep a spare quart on the boat since it will be using oil and flushing the cylinder walls with fuel since the rings will never completely seat.


And yes it's very much a rebuild issue and not the way to go when dealing with custom parts in the hands of someone that doesn't know the proper methods to adjust and install the parts or how to match them with the rest of the engine components to get the maximum from them.

does that say PRETTY MUCH BOLT ON, always trying to cover his ass..
DH!!!! yes i honed the cylinders and installed cam bearings. Ive done more engines in my sleep than you've ever thought of doing....stick to your desk top dyno and get real already
dont try to make me look like the azzhole.
what you were saying is slap on these heads to any tired old engine and you'll get boocoo HP..dont worry about the bottem.....well I did

your ass cant talk your way out of this one

and yes that e-mail is verbatum from 79's mouth

and to think I had a BRAND new set of good gt-40p's sitting there at the time that i ended up selling for 200 bucks, Im, not the thief here. im not going to tell the price what he paid for those boat ancors because its none of my business.

the block was honed and re-bore gauged, as were cam bearings installed...and no it wasnt per your big fckin mouth "pretty much bolt on"
you gave him a bonus reach around.

Hey Eric,
I can't blame you AT ALL for defending yourself.I've talked to you on the phone a bunch of times and I talked to Paul(Gun driver) for almost an hour the other nite. He's cool with ALL your work. 79 IS being slanderous and needs to stop all this childish stuff.

The best leaders get the job done without assigning personal blame

Some leaders I'd follow off the fantail, others I'd push off the fantail and Chris needs a nudge.

sorry don't thing so

regardless, I suggested a cam spec much different than what was used, I told them that the heads need ported, I supplied an intake and exhaust manifolds and rocker covers along with the heads and rockers and a push rod guage and all the AN fittings to plumb the manifolds.

the cam information wasn't followed, the suggested machine work wasn't followed, the supplied intake wasn't used. I found it very odd that after several hunder hours of use and after honing the cylinder bores are within factory tolerance. So if that is all my fault so be it, I lost money on the deal to start with and even lowered my asking price from what I had all ready told other members inquiring about the parts.

SO IT's MY fault don't think so, they did their own dance with the engine and took none of the offered suggestions, obviuosly they had a better plan than I did sorry it didn't live up to what it could have if they would have listened. They had both heads in their possesion and could have compared combustion cambers, valve sizes, spring rates and runners, flow, anything you would want to know, did they? I can't answer that, but doubt they did.

I find it odd how someone specializes in inboard tranmissions only is always working on motors and never any other type of marine tranmission, maybe that's why he's not a BBB member or the body shop is doing the work. If it's my fault I'll shoulder that no problem and can deal with the mouth, because I know the facts and can sleep with them and rest very peacefully at night knowing the real reasons why.

I spelled the way you spell, so I'd be sure you would get the point.

Paul sorry about your boat troubles and the thread drama. Eric I don't think you have lost any respect here. Forget about it.
