The original MP cam was 0.501"/0.513" lift, 288°/292° duration. The new cam is a Comp 264HR 0.512 in. /0.512 in. lift, 264°/274° duration (210°/220° @ 0.050).
I don’t know much about picking cams, but the old one sounds like it either wanted to go or was gonna start throwing parts out. Lol
Did you get your electrical gremlins worked out. Weren’t you planning to swap the harness, or something?
