9.15" it is.
I re-checked my pushrod length using 9.1", 9.15", and 9.2". 9.1" gave me a pattern about center. 9.15" gave me a pattern just to the exhaust side of center. These checks where with a hydraulic lifter pumped up and a week check spring. My thinking is with my lifter pre-load added in, 9.15" should be just about wright. Watching the rocker arm move through its stroke, 9.1" seemed to give a more even movement looking closer to 90deg at 50% lift. Any one have a good set of 9.15" pushrods with at least .080" wall for sale?
