I think the potential for much more power is there and I can say we did try a different topend package/camshaft and had good results. I can't post that info yet...sorry.
Given the Thumpr cam has kinda low lift, especially using stock rockers I was surprised.
It sounded awesome with both setups and never missed a beat. Super simple combo that made great power everywhere. When I post the dyno sheets you'll see what I mean...very W I D E powerband.
