Right on this winter me and the wife are pulling ours out and swapping it for a 360 that i picked up with a transmission amd 4 barrel intake for only $150. Kinda geeked about that deal but now its in the stages of getting torn down(not much time due to work) im just trying to figure out cam number and everything being that the gentleman said it came out of a pickup truck many many years ago. And i know our rigs run a different one than the trucks and cars.
The stock Mopar RV camshaft was, in my opinion, a decent performing unit. I did a lot of research and, after consulting with my engine builder, decided on the Comp Cam 20-221-3. The Mopar Performance P4452759AE is a fine camshaft, however the Comp Cam I chose has almost the same duration and a bit more lift, but it is more than half the cost of the Mopar cam.
The result, with .030" bore, 8.5:1 compression and a Thermo-Quad is 275hp/325lb-ft. at the flywheel.
The cam I got for MLP's 318 is Comp Cam CL20-220-3. (Cam with lifters kit.) A lower RPM range, mostly because I prefer a lower idle than most people.
I spent about six weeks and well over 50 emails discussing everything with Outrageously Vintage in Maine. (A trophy winning drag race engine builder/racer, which I believe has since gone out of business.)
