Anybody know of any worn out PW3 cams? 26,000 miles, Lifters perfect. Jim Comstock's conical valve springs.
There was a piece in Roadholder about precisely this mishap but it did not involve a pw3 .. Les Amery cast doubts on the suitabilty of cast iron as camshaft material.. saying all his are made from EN40.Before I was using JS cams, I was using a PW3, never a problem with it till the day, at a drag race, the PW3 broke in two pieces
