Good cam for 318?

While that is a popular cam with a nice idle, the main issue is probably more towards what you want from the car. Knowing this, has more to do with a cam recomendation. I wouldn't really go with a larger cam than that unless your 318 has some compresion and a decent head to work with/work done to the head. (The stock one can go far. Ported)

I'd use that cam.
