500 RwHP What motor?
Whats a good engine set up to achieve 460-500hp. I've been looking for strokers and I'm Undecided on what I should invest on. I'm looking for a good mannered engine that I can still go out of town in. Any suggestions?

LS3 with a cam and bolt-ons should get that pretty easily

on the vettes guys are averaging around 380-385 rwhp on a dynojet with an ls3. I'm not sure a cam and bolt ons will get you 115 rwhp but maybe close. I'd say a stroker with a cam and headwork will get you there and maintain low rpm driveability pretty easily.

I would think an LS3 with a cam would be tame..

Dyno numbers mean shit. You can make 500rwph on dynojet and run a low 10 if your going through a ford 9 inch and a turbo 400. Power eaters. Dyno numbers mean shit. Have fun and enjoy the car instead of worrying about bragging numbers. I would go 6.0 boosted. Cheapest route anyone can go....

You have a 402 right? Or do you have the 408?

Just a little 402.
LS7 is out of the question if your talking horsepower per dollar ratio's. Your going to pay a few thousand more for an engine thats only making mid 400's. 402/8, PRC heads, 240's cam, FAST 92/92 will get you to the magical 500 RWHP number.
Forced induction should be looked into also, You can have your 500 rwhp, and have much more HP potential then any NA engine. Reading up on different supercharger/turbocharger system would be a good thing to do before jumping into a NA project.370 CI - Twin 6766 Turbo - Jakes stage 5 4L80E - MWC 9" - Holley Dominator

OP,
If I were you I would get little cam 224/228 on 114 LSA, D1SC Procharger (8psi), fuel pump, Mototron 60's, and a good tune. You will have right around what you were looking for power wise and the driveability will be good.Last edited by Packy; 11-02-2009 at 11:16 AM.

Mr.lous How about a low 10 with a 402 on a T/A Is it possible and still have it as a DD I just got the BMR Drag set up and a performabuilt tranny with a 3k Stall...next is a strange s10 with 3.73 i was thinking. Fastest I ran with a stock Ls1 and rear gears was a 12.4
what about this http://www.texas-speed.com/SHOP/item...d=830&catid=82

402 with L92heads, all the suporting mods and a well matched cam is the cheapest way to your goal. It will be very streetable too as L92 heads don't need big cams to make big #'s.
