I've been playing around some more with DD2000 and I'm seeing the potential that both Robzr & Monty & the others here are talking about. It's really quite amazing. I think once I get this engine in place I'll be all :D !
robzr I have the Hooker SuperComp sidepipe headers which do have a large primary tube I can't remember, but it was either 1 7/8 or 1 3/4 when I had measured them. I aslo have the JCL sidepipes which have been proven on the dyno along with at the track :yesnod: .
I measured the block & the bore is the stock 4.125" :)
