Well, now that I made decision to take 8.5 cr, I just have to play a little with boost... And at the track I could always use a little racegas...

I think for 1000 crank on pump you should stroke it to a 408.

I run 11.1 compression with 15psi of boost pump gas with lots of meth injection. ls2 364
When i track it or know im going to be beating on it hard i add race gas. If you got the money and dont have anything against a 4 inch stroke crank id throw that in will make your goal alot easier.

I made 867rwhp with race gas and my engine thru a TH400, but that was at way more boost than 15 lbs.
No, just need to turn ALOT more rpm with it
