Need help figuring out a clutch to fit my '72...shop can't figure it out!!
Hi, not a transmission guy....
The motor is a newer crate motor 350. The flywheel is p/n 14088647N. Muncie M20.
Flywheel discussed below--

They've tried an 11 & 10.4...say they don't work?..
Can someone provide some insight and possibly a link for some options??...I'll be forever greatful. Thanks!

Last summer I swapped in a ZZ383. The online info from GM said that it woukd accept both the 10.5" and the larger clutch that I had on my existing 383. I ended up having to order a GM flywheel as it was July 4 week, all the mfg of flys had shutdown and no one had what I wanted in stock. GM recommended 2 flys, a lighter nodular steel and a regular steel fly. Both I was told would work with the larger and smaller clutch, I ordered both flys into my local dealership. Brought in my clutch and no way it would fit - too big. I ordered a CenterForce 10.5 bolted up fine.

The crank flanges are different for a one piece and a two piece rear seal. Your new crate engine is probably a one piece seal and needs the corresponding flywheel. The bolt patterns are different. Your engine guy should know this.
