You could get a junkyard 351W put that in the car giggle gas the hell out of it until it blows then you will know if it is enough. Then replace it with a reliable engine that makes that kind of power.mtbdoc said:I truly wish I could just drop a 500 rwhp turbo'd 351W in and see how it feels. Maybe I'd say THAT'S ENOUGH! But that isn't safe on the stock block, anyway, right? And hence my problem.
