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. |
ya the big block would be killer, but the iron block of the 454 reduces handling by a great deal. And with the LS1 i will still be VERY close to the gvw it was with the ka in it. I already got the ls1. So there is no turnin back now.
