I'm about to put a 331 in my 65. When we built the engine we used a 4-bolt harmonic balancer. I would like to use my stock 1965 alternator brackets and A/C setup. Does anybody know if I can just change my lower pulley or will there be more involved than that, if so any suggestions would help.

Thanks

As long as its the same size you can just change that one.
