Title: 428 Cobra Jet Engine identification
Post by: rdmgt500 on January 18, 2023, 05:54:02 PM
Is it possible to verify a 428 CJ w/o seeing the block scratch letter? These are the numbers I've been able to find to date:

Block casting # C6ME-A (seems correct for '68-70 428CJ)
Engine block date code is "8G23" (July 23, 1968) also seems correct. Vehicle build date was 1/28/69 from the Marti report.
Cylinder head casting # C8OE-C090-N (seems correct)
Cylinder head date code: 8L8 = Nov 8th, 1968 (seems correct)

The vin stamping on the block is illegible. See pic below.

Thanks for the help.

The scratched letter on the block is only one indicator. It must be taken into account with other indicators.

If you're suggesting that a July 68 block came In Jan 69 built car, I would say its very unlikely

With regards to heads the C8OE-N is the correct 428 Cobra Jet head. While its possible the Nov head matches a January car, I feel that would need additional authentication
