Vito,
Mike is trying to tell you in nice way that you need to read your books, like the 1972 Assembly Manual and Alan Colvin's Chevrolet By The Numbers 1970-1975.
He is just trying to help you (and other newbies also) help yourself.
But,......
Let's give Vito a break, what do you say?
Your car, with VIN 1Z67W2S506491 is decoded as:
1Z67 - corvette convertible
W-Engine code, 454ci/270hp V8
2-1972 Model Year
S-St. Louis assembly plant
506491 - Sequence Number, the 6,491th 1972 Corvette built.
Protect-O-Plate decode:
T1030CSR: - Engine code, T-Tonawanda, N.Y. assembly plant, 1030-October 30, 1971 assembly date, CSR-454ci/270hp,4-Spd.,Rochester 4-BBL, hydraulic lifters, w/A.I.R. smog pump
P2M04: Transmission Code, P-Muncie Manual 3 or 4-Speed, 2-1972 model year, M04-August 4, 1971 assembly.

K: unknown, (This should be a D month code for the November assembly of car or more likely a R = Rochester carburetor source)
11-21-71 as the sales date of car that was taped to P-O-P.
Look on trim tag on drivers door.
Should have something like this:
D04 = November 4, 1971 build date.
987 = Ontario Orange exterior paint code
421 = Saddle Leather Custom Interior
