Have any of you guys tried a McLeod flywheel #461504 for a 330 engine? Ad says 0Bal but further down ad says external balance. Confusing to us old guys. Thanks!

ALL Olds motors are external balance from the factory. Nearly all aftermarket Olds flywheels are external balance. A lot of this confusion is from Chevy-centric ad copy writers. Just be sure the flywheel you get has the early (1964-67) crank bolt pattern.

Call them to confirm what balance it is. There are neutral balance aftermarket parts, but they're less common.
