Can somebody tell me what some or all of these #'s mean? I'd like to know if this is the original block to my '72 Vette, or if the block is even out of a Vette. My Vette is a '72 Big Block 4 speed car.
On the back of the motor (I assume on the bell housing) on the Drivers side the # is 8999289
On the other side of the bell housing # J19 / 78
On the front of the block Pass side CE4(?)7580, I think the ? is an 8 but it's hard to read and I could be wrong.
that block is a 72-79 454 2 or 4 bolt main block.oh and it says some CE replacement blocks were 4 bolt main..
and its a3 not an 8 for the first number3999289
The CE stamp on the front pad is most likely indicative of a warranty replacement motor. The first digit after the CE is the year of the replacement motor, followed by a sequence number of the motor (no meaning in there). So, your CE4XXXXX motor indicates it was a 1974 replacement motor. J19 should be an October 19th casting date of the block, likely in '73, with the motor installed in your car in '74.
