got another cam question ( hope I haven't asked this in an earlier post)...the guy I got the motor I am using had no knowledge of cam in the engine. The motor (355 4 bolt, ) had all the appearances of a useful build ( team g,edlebrock carb, rebuilt hump heads, polished valleys etc.) Prior to purchasing something new ( the existing cam shows little to no wear) I am looking for info on it. Stampings on drive end are 134020. marked with one red and one blue dot. cast# 1579. didn't want to "recreate the wheel" if not needed. Although now running with vortec heads, a cam change is probably inevitable, would still like to know what sitting on the shelf. thanks in advance.
