I am changeing trannys in a 52 chevy styline. I'm using a 4x4 s-10 rear end. Not sure what ratio i'm going with yet. I'm told that a th350 does not have an aggressive enough first gear ratio for the 1958 235 i'm using. Can or should I use a 200r4. Will the speedometer hook up. What are my options. Need advice. Thanks. Tim.
