1968 427 engine pad

[Charles A.]

Could someone give me numbers and letters off of a 1968 427/390h.p. engine pad. I am use to C2's and it appears the 68 I am looking at has the complete vin. What is supposed to be stamped on the pad?

It should be the following format - 18s400001
1 - division
8 - model year
s - assembly plant
vin sequence - 400001

John, If it is a Corvette, I think you will find that "1" stands for Chevrolet, not just division. 2 was Pontiac, 3 Olds, etc.

Second stamp on the pad will identify the engine and will be TmmddXX with T as the plant code of the Tonawanda engine assembly facility, mmdd for the month and day the engine was assembled at Tonawanda, and XX as the big block suffix code.

The big block suffix code for a 427/390 should be IL for manual or IQ for automatic.
