I had Kieth Craft supply the entire driveline: MassFlo, Engine, Clutch, and transmission.
My comparison was based on an idenical engine of one of the members here (590Hp) and Kieth's sheet on his web site (580Hp). The Hp / Tq plots were consistantly higher across the RPMs measured.
I honestly don't see myself pushing this engine near it's limits as I just don't have the skills to contol it (maybe one day
). My main reason for avoiding a carb is, well, they're a PIA. (especially Holleys)
As far as "tweeking" I doubt I could do better than Kieth or Chris, but I may may fool with it at some point.
