429/460 MT Flywheel Toothcount?!

Anyone know what a 429/460 flywheel (man. trans) tooth count should be? and what Inside & outside diamter? I've got the right flywheel to go with the motor & clutch but i counted 164 teeth, and from my research it looks like a 164tc ring gear was pretty much on small blocks only... Any suggestions? 180 tc? 184tc?

Thanks

1969/70 429 = 176 teeth ~ 11 1/2" clutch.

1983/91 460 = 180 teeth ~ 11 7/8" or 12" clutch depending upon application.

What size clutch/pressure plate are you using?

What is the diameter of the pressure plate mounting holes of your flywheel?

Are there any markings on your flywheel like C9AE-6380-A or E3TE-6375-AA?

You prolly have a 289/302/351W flywheel, 164 teeth/11" clutch. It's not for a 351M/400 because those flywheels use the same ring gear as an 1983 and later 460. You're going to have to find a flywheel that matches the engine you know have. If you use the later 460 flywheel you'll have to change the harmonc balancer and spacer.

I think the Flywheel is right, but the ring gear is wrong. Every part catalog we find they are calling for a 15.5"OD flywheel and 180 or 184tc for a pre mid '79 big block 429 or 460. Just wondering if anyone knows for sure what TC to get. I'm prety sure we have the right flywheel.

I listed the correct number of teeth above for a 1969/70 429 manual transmission flywheel = 176 teeth = that info is from the 1965/72 Ford Car Parts Catalog.

For 1983 and later 460 manual transmission flywheel = 180 teeth = that info is straight from the 1980/89 Ford Light Truck Parts Catalog.

You can't have the right flywheel if the ring gear is wrong.
