Engine Identification Help
Hello everyone, new to the forums and hoping to get some information settled without breaking any forum rules.
I just purchased a 1968 GMC pickup with what I was told to be a 442 engine and transmission swapped into it. The only number I am seeing on the engine is 396026G, any information would be great!
Thank in advance

That would be a 400ci block out of a '68 or '69 4-4-2. If you look at the VIN code, stamped into the engine block onto a pad on the driver side just below #1 cylinder, the second number in that series will tell you the year. The number should read "3 (which means Oldsmobile), either 8 or 9, a letter or number (E, M, Z or 1), then six numbers. If the second number is an 8, the block came out of a '68. If it's a 9, it came out of a '69. The same number should be stamped into the transmission casing, be it a manual or automatic.

It may not have been out of a 442. Remember the Vista cruiser was also an A body and that fell under the CID restrictions at the time of no more that 400 CID.
Either way it came out of an A body, but the trans can actually be more telling. If the VIN derivative match on the engine and the trans and the trans has a tag that would have come from a 442, then that could be proof, but if the tag is either missing, too worn to read or not from a 442, or possibly from a different car than the engine, there is no way to know for sure.

So with the casting number on the block it's looking like a 76 turbo 400 mounted to a 69 400 out of an A body that may or may not have been a 442?
