Need help identifying engine
I have found an engine that is advertised as an LT1 but the codes don't seem to match an LT1.
Stamps are:
Block 3970010 with a date of A252 which is Jan. 25,1972.
Cylinder Head P/N 3973487 with a date of A282 which is Jan. 28,1972. Intake Manifold P/N 3959594
Engine suffix is V0128CTL
What are your thoughts? Is it a genuine LT1?
Thanks,
Steve

According to the Mortec Website (which is reliable to the best of my knowledge) those head numbers are in fact for 1971 and '72 LT1s. Those block numbers, again according to Mortec, were used on small block Chevys with THREE different displacements; 1969 Z28 (302) Camaros, 327 trucks (????) and 1969 to 1980 350s. So I guess you could be lookin' at the real deal.

CTL in 1972 would indicate a 165 HP 2-bbl. 350 with an automatic from a Camaro, Chevelle, Monte Carlo, or an El Camino. The 3973487 heads were also used on engines such as this with smaller valves than the LT-1, so the only thing you can say for sure is that it has an LT-1 intake manifold.
