I personally recommend a 454 aftermarket small block. Throw as much boost as you want at it and it can hold more than anything GM can offer, even the LSX block.

I'm building a 454 Motown iron block for myself, but I'm keeping it NA though. My motor now makes about 400 ft-lbs at the crank. My goal is to make about 600 ft-lbs at the crank with the new motor. A 50% increase

I know this motor has a lot more to give but: a) I don't want to overstress the motor, although I'm not sure anything below 1,000 ft-lbs would be pushing it, and b) too much power becomes unusable.

If I wanted to do something crazy I could throw a Vortech with mild boost and it can potentially make 700 bhp at the wheels easily, but that would definitely be overkill for a daily.
