440 build for a tow rig/"muscle" truck?

Pretty much, check post #111. The 360 in the truck now is in excellent shape aside from a worn cam lobe as it doesn't idle very smooth and I've replaced the whole rest of the top end with fresh parts and spent some time tuning it.

Hard learned experience on my part. Cam lobe metal is sent throughout the engine. I'd pull it clean it and throw a set of bearings and rings at it.
