changing 69 engine from 200 to 302, flywheel?

John5948 · 09-10-2006, 08:05 PM

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.

Thanks for the info, one more question did Ford use the same bellhousing for the 6 and 8?(or 250 and 302) thanks
