that was the only comparison i ever made man. 12.70s was good enough to embarass a LOT of big blocks. i never said a 340 was gonna trump a hemi, or a 302 a 427.

I didnt say they didnt!!! ahh! i said the high rpm motor benefits MORE. thats IT!


and my only point was that you can build a small cubed screamer to run with the big blocks! i dont remember saying ANYTHING about budget, hence why i admitted it was more expensive!

Its not like IM the one thats gonna go build a motor like this, I have $0 to invest in mods right now being a college student. Im simply defending the idea because I KNOW some amazing things can be done with small cubed motors if they are set up right. Everyone is so quick to call myth nowadays when they have zero personal experience with those kinds of cars. Everyone just throws the BS stock-polyglass-tire-times around and close the book based on that. Those numbers arent worth anything to someone that actually used the car for what it was made to do. (IE car enthusiasts like US)

This is every ricers argument...no offense

 

touche, however they arent typically talking about cars that are close to factory spec. im done with this one though. the cars i speak of are so rare nowadays that im probably one of the lucky few to have one kick my *** in a race.

 

Getting back to the point, I think the guy wants to build something out of the ordinary. I have and I enjoy having something that people look at and go WTF?!? haha But seriously, that's the way it is for some people and that's how hodrodding got it's start. Its his motor and his money, if he wants to build one with a different than normal displacement, let him do it. After all, it IS his.

Some people like low end grunt, some like some lope with midrange, a little top end and driveability (like me), and some like pure high RPM horsepower. If he wants to twist the motor it sounds like a cool idea. The way I see it, we're all here on the board to help keep each other from making un-informed decisions based on things we might not know, NOT to tell the guy he's wrong for wanting something different. Well, as long as he doesnt ask something rediculous that undermines the rest of us, anywayz =p I think well built, it'll run fine, he'll loose a little low end and streetability, but gain reliability and rev ability on the top end. His concern should be knowing the stock PCM shuts down at 7200, and that he needs good heads to flow at those RPMS.

My 383 is actually a 382ci stroker with a 3.8" stroke 4340 crank from a ZZ383 balanced internal in the front and has a std. bore. Runs great and I like keeping as much meat in the bore as possible, since I dont believe in 'unnecessary' machine work. The bores were perfect, so what would be the point? One motor I'm building now is a 440 ci stroked 400 and I also started a dart little M based 434. They are both internal and modified to run OEM roller cam equipment with modified timing covers and an adapter to run an opti (with a delteq to rid the opti of spark), spacers for an electric water pump, etc. The '86 IROC-Z I have now has a 350 LT1 in it... with an accel conversion intake for TPI. Solves the MAF flow issue and is nice to have a reverse cooled, aluminum headed, sequential fuel injected 'TPI' motor.

I say as long as you know what you are getting into, and you wanna do it, go for it!

 

Well, of course you can. There are 8 second NA v-6's racing NHRA and they easily outrun the 1970-something stock Cadillac 500 cid v-8's. But then again, that's not really a fair comparison. . .

Yep, money, compromises, and reliability debits can make up for alot. . . not that it makes sense, is the easiest, the cheapest, or the most streetable way to go fast.

Everyone seems to think that this thing is going to rev to the moon because of the "short" 3.25" stroke. As I posted earlier, it might raise the rpm range by 200 rpm. Not exactly the 8000 rpm screamer people are expecting. Did everyone forget about the Ford 5.0? With only 3.00" of stroke, that thing should go 10,000 rpm easy, right? The truth is that, even with a single plane intake and a big cam, they would still make peak power under 6500 in 99% of the cases.
