Mcleod flywheels

Somehow lost my flywheel
So gonna get a mcleod flywheel.i see there are two different ones.i don't see a difference what one do I need?
552 stroker 4 speed toploader in a 70 cyclone
Mcleod 463222 flywheel

McLeod 463220 flywheel

Both are 176 tooth neutral balance

I think there is a weight difference between the two part numbers.

I assume I'd be ok with either one??

I never could wrap my brain around the whole flywheel weight vs power deal on a clutch car. Either one will probably physically bolt-in OK, but I have no idea which one is "best" for your combo.

race car with gear and more track use the lighter stuff help acceleration.

Big street car with light gearing the heavier stuff will be easier to drive.

I went and ordered the mcleod 463220
