Re: hp estrimate again.
That cam is fairly stiff for a DD truck. NOT radical by any means just on the upper end of a DD working truck (2200-6400). Those heads are killing the power potential of this engine. Maybe 325hp on a nice cold day. A set of DoubleHumps that are port matched would really wake this thing up.
With 76cc heads your actual CR is likely closer to 9:1.
