Thanks for the reply Johnny, your advice is valuable. I looked up the head castings 3872702 on mor-tec and found them to be a 1966 casting for a 396 and 427. They are closed chamber @ 98.4 cc and standard size valves and large oval ports. These heads are not modified and are basically original. I will be using the truck as a weekend street toy. The instructions that came with the cam stated using a 2500 stall. Engine is builtup and sitting in the engine stand. If my combo isn't right I won't hesitate to tear it down to make it right per you alls advice....
