I have a 1950 that currently has a 216 that just won't turn over connected to a non functional transmission. First off, I want to pull this set up but can't figure out where to attach my engine lift? Could you please help me. Secondly, I've found a running 235 with functional transmission that I'm thinking about buying. Is there anything I need to do to prepare for the swap, and is it worth it, or should I rebuild my setup?
