Thankyou Bill. These are the only ECZs I've ever seen.

46yblock (4/3/2010) I have 5 main caps taken from a 312. Lined them up on a table today and noticed one had bolt holes that were at least 1/4 in. shorter than the other 4. Numbers on 4 are ECZ 6329A, and on the oddball ECZ6325A. The short cap came from the rear of block. Dont recall reading that there were 2 styles of 312 caps. Did the '57 312s have the shorter bolts?Short one is rear one to clear rear seal housing lip.
