I cleaned up that bottom set of numbers and its the same as my vin. So, I know its the original motor. Not sure what the upper set mean though.

Vette(s): 1972 LT-1 convertible with factory air. 2017 Black Rose Grand Sport convertible.

CLA is a 350ci 180hp automatic transmission.

I don't have the decoder for the date stamp.

Vette(s): #1-1974 L-48 4spd Cp Med Red Metallic/Black deluxe int w/AC/tilt/tele./p/w-p/b/ Am-Fm/map light National/Regional/Chapter NCRS "Top Flight" #2-1985 Bright Red/Carmine Cp.L-98/auto Member: NCRS, NCRS Texas, Corvette Legends of Texas

"V" is the Flint Engine assembly line, 12= December, 03= 3rd day of December. The serial number gives the year, in this case it is 1977. "CLA" is L48, 350ci engine, Federal Emissions, for a turbo 350 trans, as has been stated. So the engine was assembled and date stamped at the Flint Engine plant on December 3rd, 1977. The VIN was stamped at the St. Louis assembly line.
