T0912CMJ
This is the number on the engine in a 1974 vette.
I am not sure it is the original engine. Anyone to tell me what engine it is ?

Most likely a truck engine.

my 79 doesn't have the original engine. Engine code is K1010 CMJ (same code that you mention). According to Mortec site, it can be a 350 ci (in early 70s) or a 305 ci. I tend to think that the engine in my Vette is a rebuilt engine because I had a Firebird 75 with a 350 ci 4bbl in it (between 79 and 85), and I can confirm that my Vette engine is extremely responsive and nervous, delivering accelerations extremely better than those I got with my Firebird.
I made some research with Google on the code CMJ, and I remember that in a discussion group on a site about engines, someone wrote that some engines in Corvettes were having that three letter code (but I cannot confirm...) Is it possible that some crate engines had this 3-letter code ?

I believe Adam's Apple and RoadRacine are right.
I think this engine is a 1974 Camaro 350 engine rated at 160HP and installed in Police cars.
