Re: 6223 steel crank
366, 396, 402, and 427 all used the same 6223 crank forging at one time or another. The cranks were finish machined slightly differently due to balance issues, but the cranks are basically the same. They are all the same stroke. I have a 366 truck crank at the shop I am getting ready to use building a 427.
