Default 1972 VIN Codes (Part of a series)

Please Note this is NOT going to be 100% accurate. Numbers changed, I coulda mis-typed, but this is the best I can do as a back yard mechanic to help you out. This came from 3 different books, and I tried to put all 3 into one page for ya. Please look for the book CORVETTE BY THE NUMBERS for more accurate information. Thanks.

1972 Corvette

DECODING THE VEHICLE IDENTIFICATION NUMBER

For the first time, Engine codes were in the VIN

VIN # is stamped on the inside of the A pillar windshield.
Convertible Vin #s were 1Z67K2S500001 TO 1Z67K2S527004
Coupe Vin #s were 1Z37K2S500001 TO 1Z37K2S527004
Symbols, Letters and their meaning:
1st Chevrolet
2nd Z for Corvette
3RD and 4th = 67 Convertible, 37 Coupe
5th Engine
K = Base 350
W = LS5 454
6th Symbol indicates Year (2 = 1972)
7th Symbol indicates Assembly Plant (S = St Louis)
The last six symbols are the production numbers.

1968 1978 Corvette Trim Tag ID
Upper right corner is body build date
A = August 1971
B = September 1971
C = October 1971
D = November 1971
E = December 1971

G = February 1972
H = March 1972
I = April 1972
J = May 1972
K = June 1972
L = July 1972
The Second and Third numbers were the day of the month that production of this car started.

On the left side is a word TRIM followed by the following:
400 = Black
407 = Red
412 = Blue
417 = Saddle
404 = Black Leather
421 = Saddle Leather

Just right of that is the word PAINT followed by the following:
912 = Sunflower Yellow
924 = Pewter Silver
972 = Classic White
945 = Bryar Blue
946 = Elkhardt Green
973 = Mille Miglia Red
979 = Targa Blue
987 = Ontario Orange
988 = Steel Cities Gray
989 = War Bonnet Yellow

ENGINE CODES

1972s consist of 8 characters:
1st is Assembly Plant
2nd and 3rd are Assembly Month
4th and 5th are Assembly Day
6th is C for Chevrolet
7th & 8th are the Engine Code Suffix

Thanks from another 72 owner. I have most of these, but sure I'm missing something...

So if my engine code has CKY in it then it is a CKY 350, 255hp, 4 Speed, Mechanical Lifters, Holley 4 Bbl without AIR Injection? Smog pump is no where to be found and I have always been told that all 72's had the pump from the factory.
