I've started on the 454 for my wife's vette. I was able to find the casting numbers and dates. I suspect that the heads have been changed. The casting date on the block is '82, the heads '78. no big deal, open chamber, oval port, 120 cc. The big question: I could not locate the application code on the block, preceding the serial # the code is CCJ (before the serial and the same size as serial # seems wrong, I always thought that the application stamp was in slightly larger letters and after the VIN stamp). Also the block is painted (original as far as I can tell) a strange sea-foam green, almost like the old Rambler color. I don't think that this started out as a marine block, and was not a crate motor, since there is a VIN # stamp. Any Ideas?

Okay, got it torn down and degreased. Ready for machine work. One broken piston skirt, two broken rings and one oil ring overlapped vs/ butted. Enough cylinder damage to require .030 to clean it up on the one with the oil ring problem. no cracks or obvious catastrophic failures. cupped lifters and round and galled cam. It looks as if one or two rod bearings were spinning. Have to turn the crank too. I'm happy, it could have been worse. BTW, I found the correct application stamp. It is on the top center of the timing cover flange. TKA, Mortech doesn't list the codes, any other links for Big Block codes?

I didn't think they put a 454 in a late 70's early 80's vette. Also not sure why you are looking for an application code (or suffix code) since that engine didn't come in the vette from the factory. I could be all wrong because I am confused about what you are trying to accomplish here.
If you need parts just verify the block casting date. I just finished a '66 427 build up and have ordered parts for everything from a '69 vette to an '80 suburban.

Thanks Jason, I was just curious as to where this block originally resided. No 454 in a Vette after '74, but the '76 is the same car, so a swap will be easy. Casting date is 4-15-82, heads have likely been changed, casting date of 11-78 and 12-78. About the funny green paint, after degreasing and pressure washing it appears to be the GM light blue, discolored from oil leaks, heat and age. Now the fun starts!

Thanks guys!
