If so you are going to need to up the compression, some really good heads and a roller cam to start. But that's just my opinion.
Be ready to spend some $$$.
X2, you can do it but you will definately need a good set of heads, a 750/850 dbl pumper carb. I've got a flat tappet cam that will make that much HP and more, i'll post the cam card if you want, Also i'll guarentee you that are pushing limits of the Scat 9,000 crank at 500 HP. This i speak from experience after building a 388" for a friend with a cast steel crank on alcohol. It ran 6.39 @ 112 1/8 mi for about 40 passes in a 3000 lb Camero. It pulled the #2 main web right out of the blk spun 3 mains and cracked the blk all the way up into the lifter bores. That crankshaft was running around like a jump rope.
