He also said a cam would sound smaller if I stroked my 318,can't have that,still trying to decide, lookin for a shop that knows mopar's.

That he is correct about.

Good,does that means I can go a little bigger on the cam as long as I match it with the rest of the build ?

Yes. Cubic inches has quite an effect on the cam choice. I assume when you talk stroking your teen you mean using a 4" crank. If that's the case, going from a 318 to 390'ish cubic inches you'd want to add at least 10-12 degrees duration at .050" lift for it to operate in a comparable rpm range
