...if i had a money tree it would be a no-brainer, but i'm sincerely trying to decide between this upgrade and the big bore kit (790/America), and it just seems to me that the latter will produce more usable power.



If you have a 790 motor, the cams upgrade will be minimal, where as the 904BB will be substantial.

From all the dyno sheets I've read, it seems that:
on a 790, the 904BB will get you close to 75-80 with a FREAK type kit and good pipes.


on a 865, cams and carbs will get you 75-80 with a FREAK type kit and good pipes.

I wish someone made a 10.5:1 drop in piston for the 865
