Erson cam

I grew up in the "old school" days and managed a parts store/speed shop before Comp Cams was in business. We sold a lot of Crane, Isky, and TRW TP series cams. At that time Crane, Erson, Isky and Schneider were the top brands. Cam technology was advancing faster than drivetrain parts were. Rarely did we sell a cam with more than .500 lift and the cam grinders made horsepower with duration and not much lift. Many of the street cams were installed with stock valve train components and that worked fine. The Purple shafts were of the same era and worked well. Your machinist may have that cam laying around and wants to sell it or he may have put it in many engines with good results. Nothing wrong with a old school grind. They have a fun lope at idle and do make horsepower without fancy and expensive valve train components. tmm
