well only good machine work and assembly will help you here (as with any build for that matter).With a legit setup I would expect a cast crank to be good for 450-500hp given that everything is correct.clearances etc... also depending on how tight you want to spin the motor. If you're wanting this for a legit street/strip motor cast crank will do you just fine.

yep 500 hp, 7000k with a good balance and tune.
after that i'd get nervous..

Or get a cast steel after market crank there inbetween factory cast iron and forged crank in strength, closer to forged for about $250 or 4" for same price and don't have to spin as high to make the same power.

I ran my old combo (360, stock crank, stock rods with ARP bolts, and JE pistons) for 8 years on the bottle every pass in Colorado. It ran 11.1 @ 121mph...no problems at all....not saying this is a good thing to do, but it did work just fine.
