Just thinking out loud. what about building a 360 (or even a stroked 360) on the side. It'd minimize your down time when it came time to swap & there'd be a significant gain in torque which you could definitely use.
I'm always looking at local ads for some kind of small block in running condition but I'd like to avoid the additional expense & save it for other improvements later. When I bought a package deal of parts a couple of years ago for things needed on my son's Coronet & my Scamp, it also included the 340 intake. I later got the new carb, brackets, linkages, gaskets, filter, etc., but wrongly assumed the carb would fit.
