Well Bigb, those numbers don't seem to correspond to anything I can find, but if it's a Saginaw 4 speed transmission, it would be "correct" for your car. For 1967, the only Camaro's that came with a Muncie 4 speed would be the 350 and 396 engines. All 327's came with a Saginaw (if ordered with a 4 speed). Are there any other numbers cast into the transmission?
