Default changing 69 engine from 200 to 302, flywheel?

I'm changing over from 6 cyl 200 3 speed to a 302 4 speed toploader, can I use the same flywheel or will I have a balance problem?

I don't think its the same. I believe the 6 cylinder cars had a zero imbalance flywheel.

If your 302 is 1980 or before, it needs a 157 tooth 28 oz flywheel. Post 1980 are all 50 oz flywheels.

All 351w are 28oz.

You can not interchange the flywheels from 200 6 cyl to 302. You need the specific flywheel for the engine. As Frank said above, up to 1980 28 oz afterward 50oz imbalance.
