Which Cam in 318

I need some opinions on which cam to use in my 318. Car is 1964 Valiant, I'm guessing around 3100lbs, 4spd with 8 3/4 / 3.91 gears, suregrip. Motor is stock bottom end, mid eighties 318, with 302 heads, Edelbrock Performer intake, jetted down 750 Holley, and Spitfire headers. Exhaust is not yet purchased. That will be my next question. Car is for occasional street use, and rare trip to track. Would like for it to go good and sound good. What do you think would be a wise cam choice? Thanks Mike
