Ok old timers , i need your knowledge on this cam ! Direct connection camshaft

I agree 100% the cam is "pretty big" for a 318. You can overcome a lot of that by installing it as I described though and running the appropriate gear set. I don't agree though that the cam is necessarily "not as good" as some modern grinds. It certainly is. Those cams were ground with the .903 Mopar lifter specs. They are REAL Mopar cams with REAL Mopar lobes, so that makes them better than a lot out there today. Yup, you can certainly call them dated and they are, but they still flat out work.
