Engine Cams

[Hubert]

Hello all. I have a 1974 roadrunner 318 4 speed. The original owner put a larger agressive cam in the car. Can anyone tell me what the original 318 cam would have been as i am looking to have the engine rebuilt back to original.

Sealed Power/ Speed Pro sells a stock type replacement cam close to a stock 340 cam. CS-1006R I think is the number

Since nobody except you will know the difference, I would use a different grind that will still give a smooth idle, yet provide a a little more power with no downside. Isky 256 Supercam.
