Andy...yeah, guess I really didn't make my point....IMO you can go bigger and make more overall power AND have great streetability by phasing a bigger cam in early.
This is a 517 with a BIG hydraulic (>265@.050...comparable to a ~275-ish Solid)roller and the MW Stage VI Chaps, at 12:1 it's got an awesome throttle response punch and a great powerband even in a 3700 pound 3.54 gear car. Even at 2500 rpm (if I swapped in a stall that tight) it would pull a freighliner truck with the MW ported Indy dual plane. I may go to the Indy rat roaster and 2 x 4 later (like the one you tested) but it'll probably be swapped into another car at that point.
