I just found an original 302 Factory 4V motor out of a rusted out '68 fastback. It has never been gone through or rebuilt, and has the original Autolite 4300 carb. Engine ran when car was shut down a long time ago, and it still turns freely. Looks like it had some kind of pollution plumbing built into the heads. What's this motor worth in good rebuildable condition? Thanks, and Merry Christmas to all.
