If it were me, I would keep it simple and go with a 283 if I could find one or a 305 with a quadrajet. I do like the larger bore of the 283 with the shorter stroke, less prone to detonation. I personally prefer the 307 to the 305 for the same reason, but they are harder to find in good shape and have only one piston choice for a rebuild where the 283 has several.
