So there dilemma is which way to go:
If I could get my hands on aluminum block, I'd do it as a 440 stroker. With the siamese bores, it should be better than the iron block. I'd also look at using Arrington's new roller rockers so I could bump the RPMs higher.
A 426 stroker with a Magnuson SC on it running about 10-12lbs of boost.
I think this option is quite ready for prime time. Twin Turbo 393 would be sick. Jack up the boost and hold on for dear life
In all cases, Paramount Performance drive train to handle the power and Nitto NT05rs (rear) and NT05s (front) on stock rims.
All I need is $$$. Damn, where's my lotto ticket!?
