Do the 396,402,427, and 454 all share the same main and rod crank journal size? Thanks

Thanks for the reply chevelle. I appreciate the help. Can any of the cranks be interchanged for different combinations?

I thought the early 396s and 427s (65-67) had a smaller journal size than the later 396-402-427-454 engines?

The "W" family has different journal sizes.
