Re: [Amc-list] Mixing up cranks and flywheels - adapter?

[Frank Swygert <farna@xxxxxxx>]

You probably saw it in a copy of "Performance American Style" publisehd by AMC in the early 70s. All the AMC vendors sell two different adapters. One requires machine work to the crank so is best used when the engine is being rebuilt. The other costs more but bolts on. It uses a 1/4" spacer between the bell housing and engine to make up for the thickness of the bolt-on adapter. After the cost of the machine work they are about the same in total costs. For high performance it's considered best to go with the machined adapter, but for street to mid level bracket racing (say 11s and slower) the bolt on one is fine. A 10 second car takes a lot of power!

1970 401 crank + 72-up 401 flywheel.

What do I need to do this?  Is there some kind of adapter or spacer out there that is required?  I could swear I saw something like this on a site in the past (perhaps Bulltear?), but I cannot locate it now.
