Cam Selection 318/Auto (Low 15 Sec Bracket Car!)

If you are using the manifolds, a Comp Cams XE262 cam would be a god match, with relatively smooth idling.

If you upgrade to headers, give the XE268 a try, 1500-5800 rpm range with a lopey idle, but still decent low end. It may work fairly well with the 3.55s and stock to slightly warmer converter.

With either, run a 600-650 CFM Holley or Edelbrock carb.
