The pistons are very similar to a SBC. The 305 piston can be used in the 250, but because of the wrist pin location CAN'T be used in the 292. There was a real good dicussion sometime ago on the subject.

When I get the pistons I'm going to check the compression height against one of the old pistons. I'm thinking it may not be standard.
