First thing first check the signal wire at the starter, have someone turn the key and put a test light on the small side at the starter.

Also make sure all your grounds are hooked up. Engine to body, body to battery etc. If the motor is not grounded it won't crank either. I just threw a 91 motor in a 52 truck using a 80s column and it started so don't thinking mixing and matching this stuff matters
