I have a 1967 small block (not original) in my Vette. I'm having problems getting info on the numbers. Primarily the suffix info. If the story is correct, it is a gm crate motor from 67'. I can't decipher much more than that.

The 2657 is correct for a 67 327.
An original 67 block would have an H, two letter suffix or a KH. Most of the counter exchange GM blocks back in the day had a CE suffix. I'm not familiar with VT but someone else will chime in I'm sure.
