Cast Iron 164 Tooth Flywheel for 1969-1973 Mustangs with 302, 351W and 351C Engines and Manual Transmissions.

Flywheel Specifications:
- Ring gear: 164 Tooth
- Cranks bolts: 6 bolt
- 28 Oz. balance

Tech Tip: If you have a 1965-1966 Mustang with an original 160 tooth flexplate/flywheel the 157 tooth can be used as a replacement as long as you have a 10.5 in bolt circle and are using the "small" bellhousing. The small bellhousing is typically aluminum, the larger 164 tooth is typically cast iron. The 164 tooth flexplate/flywheel can NOT be used as replacement for the 160.

*Will only work with a diaphragm style clutch.
*Will NOT work with CK2 which is a 3 finger style clutch.

I have a 1970 351 Cleveland. I am swapping out my tired M 400 in placeof the C. I have a 164 tooth flywheel from an early 80s F series with the SBF bolt pattern. I am assuming this flywheel is correct for my swap but am not 100% sure. Which clutch?

Asked by: Shawn
Hello RK, I thought the tooth diameter of the ring gear determined which bell housing to use. I have a bell housing that used a SBF 164tooth flywheel. It is the larger bell housing. But it is Cast Aluminum not Cast Iron. Thank you. Shawn

Will this fit a 1979 mercury capri with original 302 in it

Asked by: capri02
No, the 1979 Capri is closer in design to the 1979 Mustang, so you're likely going to want to seek out those parts - they have a much better shot of fitting.
