Id love some feedback.

How are you coming up with a total destroke of .128"?

By offset grinding the crank rod pin .064". Since the crank pin is 2.249" and his rod big end is 2.1", there SHOULD be enough room.

We have spent many nights on the phone coming up with what will work, since he already had the pistons, copper gaskets and knew the rods available.

Doh! For some reason I was thinking the offset cut would me more than that.

I got goose-bumps reading your description. (wouldnt mind trading engines with ya for a day.)

However, you stated the were you able to use 5.850 rod with a stroke increase of .194. With a compression height of 1.460, I will have to de-stroke the crank to enable the use of 5.850 rods and a .070 gasket.

Also, Id love to see some pics of your intake, billet girdle, oil-squirter mounting and whatever other pics you have. I could use more "fodder" for my own ideas. (Its cool to see these engines being developed)

keoki, where in Tampa are you? I'm up in Bradenton a few times a year and would like to check out both yours and Joseph's cars

[Keoki1978]

It was all just a BS thing, I'd love to build a stroker 3500 to a 3700 with titanium rods, billet steel crank. I didnt do the math but your right, I couldnt use 5.850 length rods with a 1.460 comp height and a 3.504 inch stroke. But I suppose I'd be able to use a 6 inch rod with a 1.154 comp height pistons. Anyway, I'm in tampa area by the airport, or town n country area for those that know the area..

[ForcedFirebird]

Man, we are serious here :P

I'm not kidding when I tell you John and I have been on the phone literally for hours planning this build since about November.

Don't mess with us like that

[Nightingale]

Lol I was gonna say those numbers weren't adding up....pistons would be sticking out almost a quarter inch above the deck lol.

I figured as much. The outlandish stroke was the first dead give away The "smarmy" attitude was the second.

I figured that Id ask the questions to put ya on the spot. (photos, numbers etc.)That way if there was a lagitimate mistake or typo, it woulndt have to start another thread fight. You never know when there may have been some genuine honesty in a statement. (Ive had a pension for pissing people off lately)

In any case, I appriciate the honesty.

I just think you guys are trying to much with all that. If I had the money to build what I described, that would be the motor to build. Save the money your gonna spend on destroking that crank, put that with the money for the rods, get some lite weight titanium rods in a 6 inch length, some lite weight pistons, fab up a sheet metal intake, search for a shop that has cnc capabilities to cnc the chambers and port match the intake side, then get some titanium valves and retainers, a solid roller cam, forget the mega squirt, get the Electromotive Tec 3, its already got its own coils. I garrantee you that motor will spin to whatever rpm you want and keep making power till the bottom end falls out. I've been involved with a few builds, mostly 350 GM's, stroke em out to 3.75" on a 4.125" bore, and these are revving to almost 9grand. That mega squirt thing is entry level shiznit, would of never made it to where it is now if it wasnt for people trying to be cheap. I'm running a FAST bank to bank system on a turbo 3100. Hydralic flat tappet cam specs say engine should run to the 6900RPM's and start making power above 3000. But I'll believe it when I see it. Anyway, just wanted to put my 2 cents in and trying to point you in a better dirrection...

Im sure that I could hitch up some magical unicorns to the front of the car and rub it with cheetah blood and go the speed of light too.

So your determined to build a 3400 out of a 3500. Damn dog, just thought that if you wanted to build a HARDCORE 3500, why not just build a 3500. Why mess with destroking, oh yeah, that few extra rpm is gonna kill them hondas running round in miami right. If you didnt want other peoples opinion, then you 2 should of keep this off the net and between the 2 of you on the phone. In my opinion, your not pushing no envolope or building a hardcore 3500, your simply screwing up a good motor.

Ill point you in a better direction. You can take your bullshit somewhere else.

Damn.....Dog?

Whaaat? you dont like unicorns?

Dont worry about it Ben. I actually like guys like him. The'yre fun to mess with. Like I said, I have a natural pension for starting thread fights with dumb people

Ignorance + lack of mathmatical skill + IQ of "jar of mayonese" = THIS GUY!

more fun for me
