318 rebuild/upgrade

I would use the 318s (heads), and also use a 360 2 bbl cam as this cam has more duration and lift that will give better power and torque and not kill you at the pump. I use to run one for years until I wore the engine out, worked great for towing the race car and for street driving. Surprised many a stang and chebby in the tow truck.
