I have a 455 olds that I rebuilt and I'm currently running 10mm wires with NGK plugs with a heat range of 6.  I have a starter battery for the engine and a deep cycle for everything else.  I can buy either a 94amp delco or 120amp.  Would I be fine with 94 or is the 120 my best bet.  I wasn't sure if more is better in this case.  Thanks!

Anything after about 80 amps requires a serpentine or dual belts to get it all anyway.

94 is more than enough. IMO.
