Originality / BL code rear axle in 68Z28
« on: April 16, 2021, 12:17:13 AM »
Looking to verify that a non posi. 3.07 12 bolt was available to order on a 1968 Z28.

 Yes? No?

Decoding/Numbers / 68Z28 #'s
« on: April 19, 2017, 06:13:15 PM »
A friend of mine is somewhat interested in this 68Z on ebay, and has asked for me for some input.

I'm looking for opinions in the deck stampings on the engine.
There is, obviously, a discrepancy in the assembly date on the pad - Nov. 29 (11/29/67), and the casting date on the block - Dec.22 (L 22 7).
The pad numbers don't really look fake to me, but I'm not an expert on pad stampings.

The heads are dated Sept.15 (I 15 7)
Intake - Oct. 4 (10 4 67)
Trans - Dec. 5 (T 05)

Everything seems to line up with a 12B car, except the block casting.

Is it possible, or is there any noted instance of, a block date being mis-cast. so to speak? Doesn't seem like it would be hard to mistake an "L" for an "I".
