    500 RWHP? Is it possible?

    What would be a good way to get 500 ponies to the rear wheels, naturally aspirated? Any chance you could get a smooth idle? If this has been posted before,please point me in the right direction. This info is just research for now but would like opinions, ideas and thoughts. Even skecthes on a paper napkin would be welcomed. Thanks for your time..................oh yeah almost forgot, the platform would be a LS1. I want to keep the aluminum stock block.

    Not with a smooth idle.

    Basicly the car won't be very streetable, but it can be done.

    it won't be do-able on a 346ci without a choppy idle unless you add juice.
    you can go with a big cam, Trickflow or AFR 225 heads, ported 90/90 intake, and all the other goodies and probably make somewhat in the 475rwhp-515rwhp with a good tune.

    So an LS3 or an LS7 would be better for the job? Man, those do not come cheap but you got to pay to play I guess. Gents thank you for your quick response and if any one else would care to give thier 2 cents please feel free. Once again Thanks alot guys.

    well you'll still need a mid sized cam w/ excellent head & intake flow on a 408 to hit 500rwhp NA. though it is a preferable build due to affordability. but with the money you spend on a 408 shortblock you could save a little money and get a forged 347 built or rebuild yours with pistons & rods for a little higher compression than stock, small-mid sized cam, ported heads, & spray it a little to hit 500rwhp. Personally I'm not about the juice, but as far as saving as much money as possible on your ls1 motor it'd be a likely bet for most people. If you want to stay away from spray, like others, I'd also vote for the 408, or to stay aluminum block the ls2 402.
