360 pairing with a 3 speed help...

Pffft. "better" is a relative term, and you'll be relatively far ahead to

Buy stock 360 ' wheel
Add bell housing

Stir together in engine bay and cook at 257 degF or until tires start to melt.

If you don't know why it's "better", it's "better" that you leave your wallet in your pocket on the issue.

In a pinch, you can buy aftermarket wheels with removable balance weights, or you can buy a internal balance wheel and have the world's cheapest machine shop modify to suit using the many blueprints of said 360 flywheel found online.

Or you can run a 318. Or a 5.2 Magnum.
