Cams for 318's

Too many variables to just throw out a recommendation but I'd suggest you get the head casting numbers and run a compression test. Then decide what the rest of the combo will be. The cam needs to match your rear gear and converter . No good to have a cam that starts to pull at 3500 and tops out at 6k with 2.97 rear gears. You will never use the power. Don't over cam!!! Weight of vehicle intended use? Highway usage?

The head casting number for the driver side head is 4027593 which is period accurate. What I read said it is for non-air pump equipped models. What was the air pump for? The carb is a proformance 650 and the intake is an Edelbrock LD4B.

Also, I finally figured out that a "302" head refers to the the last 3 casting numbers and not the displacement of the engine it comes from. I found a source for rebuilt 302 heads, so I'm considering swapping the current heads for those now. If I do that does anyone know if the COMP 252/252 cam would work well? Vehicle is like 3,800lbs.
