How about just using a stock 340 or 360 cam. Either one should give a noticeable improvement over the 318 cam.
I'm currently doing a low budget build for my Duster with parts I have just to get the car running and mobile. I'm doing a .030 teen, #675 heads cleaned up, stock 360 cam, Action plus with spread bore, headers, factory high stall converter and 3.91 rear. Hope for 14's or low 15's out of this. Just a thought.
