Dad’s 1969 Dodge Dart Swinger 340
Camshaft time. As I said, this is supposedly a Mopar Purple. I brought it to work where we have a standing micrometer (whatever its called). I zeroed the micrometer on the heel, and them measured the lobe. I got 0.312" of lift on the cam (both intake and exhaust), which translates to 0.468" at the valve. I dont see a 0.468" lift. I see a 0.474" lift. I would need 0.316" lift on the cam for the 0.474" at the valve. Nothing else is close. Of course, I am only looking at Mopar cams... it could be another cam. Howards has a 0.465/0.465 camshaft... but they would mark their cams. It is there any other way to verify what this is? There are no stamps on it. The only other indicator is a red paint mark on the back end of the cam. The cam also had a 2* offset key. It appeared to be put in to retard the cam.
