... which is why I said "no" in my response. Just an H/C/I on an otherwise stock 302 won't do it, because the stock block isn't up to the RPM required. Now, if you're going to build it from scratch, that be a different story ... (and I would stroke it then anyway, why the heck not)Joes95GT said:1) Spin it to 7000-7200.
2) Change the pistons.

With about 10.5:1 - 11:1 compression, and a piston that will accept a 2.02 valved head, you could probably do it fairly easily. I'd bet that you could do it in such a way that it would still be fairly street-able, too.

I think what he meant by "stock block" was the stock internals too. The internals, mainly the pistons, wouldn't allow you use a large enough cylinder head to cut back on the RPM necessary. With a 1.90 valved head, you'd probably need to spin the motor to 8000 to get 400 RWHP out of it. At these types of RPM levels, you are taking a chance of a rod exiting stage left...95snoozer said:stock block not spinning high, the answer is NO
it just wont happen due to the laws of physics.
you could take every bit of parasitic drag off the car, power steering a/c / run an electrical water pump and you would fall short
272 with stock heads? Who?! They must be a damn good engine builder.jghood13 said:there are people on here with 325 with h/c/i and people with stock cam and heads hiting 272 so why is 340 at the the rear wheels not possible I could see the happening
There's what, one person on here with 325? Two? These people with 320+ are the statistical outliers, on the top end of the spectrum. The vast majority of us with good H/C/I setups are right near 300 plus or minus. Sure 340 is possible, but I think it is very unlikely.jghood13 said:there are people on here with 325 with h/c/i and people with stock cam and heads hiting 272 so why is 340 at the the rear wheels not possible I could see the happening
I wouldn't try it on the stock shortblock. You'll be sorely dissapointed. If you can get it to run right, you'll have to knock the limiter out of it. If you knock the limiter out of it, you'll have to keep the revs above 2000 all the time. If you still run about 2000 RPM no problem, you'll be shifting at 7000. A stock rotating assembly doesn't like it. Rods like to detach from the crankshaft and exit stage right. I've seen it.jghood13 said:you know what Ill just have to hit 340 cause I know it wont take two much more just a good combo built to the max and she will still be streetable
