That is pretty good info; and, I think we are heading in the same direction.... helping the OP to refine his goals and working from there, AND try to see what can be done with what he has, since that is what he asked. I just don't want to presume that he does not want to spend more $$. Plus, we don't know his comfort level with doing a lot of his own work like head porting, or engine assembly. So the 'under $1k', home-built hot 318 may not work for every case.
