[QUOTE="BBR, post: 17766, member: 17867"] Rich: Here is the cam we developed with Powroll. These cam specs are directly from the install sheet: Intake opens: 25 degrees BTDC Intake closes: 55 degrees ABDC Intake lift: .257" Clearance: .003" Exhaust opens: 51 degrees BTDC Exhaust closes: 24 degrees ABDC Exhaust lift: .256" Clearance: .004" This cam was designed to run with the stock springs - so it is pretty mild. I don't happen to have the duration at .050 specs. You could probably call Powroll for that. We're working on a billet wonder cam (with trick springs) but that is out a little ways - and it's top secret - so don't tell anybody. [img]http://dirtrider.net/ubb2/smile.gif[/img] Duane [/QUOTE]
