Help needed with sb 318

Sorry......would probably be a better fit in a D bodies forum, but couldn't find one of those. The "trucks" Dodge forum seems to be more about finding spare parts and less about engines. The only thing I have in common with them is the engine. The place to be for engine help would seem to be here.

Perhaps if I fudged and suggested my intent is if I can get the 318 running good, my plan is to put it into my cousins old 66 Cuda......if I can ever find it?
A few ag manufacturers used Mopar engines in their products. Slant 6's in haybines and combines, 318's in combines and sprayers and such. Heck even the old 392 Hemi's in back up generators and air raid sirens.
