429 flywheel help!
i need a flywheel for a manual trans for my 77 f150 4x4. I was told that a 360/390 wheel and clutch assy. would work for it so i was also wondering if a 352 flywheel and clutch assy. would work. the 429 has a 2bbl carb and is out of a 71 merc. anybody know if the 352 flywheel and clutch would fit a 429?

I don't know what else fits, but I have one that's been laying around for about 30 years. It's supposed to fit a 429/460, but it may have (probably) come off a 400M. It's been so long, I can't remember for sure. I'm pretty sure it came from a pickup. The 351/400M used the same C6 automatics and torque converters as the 429/460, so it seems reasonable they would use the same parts in a manual trans.
I don't have a use for it, as I'll likely never build the car I bought it for, so I'd sell it. Weighs a ton. I just have the factory cast iron bellhousing and the flywheel. Been laying around for 30 years, so it definitely needs cleaned up and resurfaced.

well, i heard that the 351m and 400 flywheels would fit, but wouldn't be balanced quite right and the motor would shake like crazy. i'm sure a little more research wouldn't hurt though.

I am in the same boat as you are. I am building a 460 (which uses the same flywheel as a 429) and need a neutral balance flywheel. I did some looking on ebay and there is a company in california that sells aftermarket flywheels for around $140. Don't know too much about them, but they look good.

Whoever told you that was wrong. A 351m-400 flywheel will not bolt up to a 429-460 crankshaft. The bolt pattern is too small.
