Prospective purchase engine ID help, please!

3999289 is a 454 as you stated, they were produced 1972 - 1975 for passenger, Chevelle, Corvette, and 73-75 for Monte Carlo's. The CE 103507 designates it as a warrenty replacement block. CE stands for Counter Exchange. I wouldn't think it would be a warrenty block for a 67 vette since the 289 blocks weren't produced until well after the vette's warrenty had expired. The motor should also have a casting date stamp on the rear topside of the eng the opposite side from the casting number. The 103507 is just the sequence number of CE engs as far as I have been told.

I appreciate the response. I discovered the CE was counter exchange and figured the age difference as the original got scattered in 1973, according to the current owner's investigation of the car when he bought it in 1981.. That made sense. Just was at a loss as to the remaining numbers.

All of the above doesn't mean a thing, save satisfying my curiosity, because if it isn't the engine the car is born with, then it is a replacement. I did know it is a replacement. Got a kick out of the bore being the same, supposedly.

The car runs exceptionally well, BTW.

Again, thanks for the help!
