How about not allowing a header on the rotary? We already have rotary specific engine rules, and I'd ASSUME that the use of the stock manifold cuts the power output ability a fair amount. What kind of #'s are the Spec-7 motors putting to the ground???

My Pro7 (ITA engine rules sans header, and requiring an 81-85 intake carb combo) put down 118 horse on a dynojet. Most dyno between 113 and 118. 118 is the high end.
This was with a 2.5 inch full ength exhuast with dynomax ultra flo muffler & a Yaw -ish carb
