Pad on the front of the block below the right head has the engine assembly date and partial VIN of the original car it went into.

VIN of the vehicle is on the driver's windshield post.

Trim Tag is on the driver's door hinge post.

Start with these.

Tranny and frame are also stamped with a partial VIN, but these are harder to see.

There's a VIN on the 4-speed, but don't know about the auto. Matching numbers could extend to casting numbers and date codes on heads and exhaust manifolds plus date stampings on alternator, master cylinder, starter, carb, etc. Depends how crazy you are...

Default Vin

The VIN is under the compressor/under the right front valve
cover. Use a light because it probably is covered in dirt or painted
over. If it's painted over clean until you can see it.

Example of a VIN -
1 means Chevy Z means corvette model 37 means coup L means
base or standard engine 6 means "76 model year S means St Louis
4 is a place holder and the last 5 digits indicate it was the
18278 vette built that year. (This is an example from Corvette
Fever).

How did Barrett-Jackson get involved?

16S4435 is an incomplete number. Take another look. It should be 16S43505 to match the VIN.

VIN is incorrect No J code for 76; fifth character should be L or X.

Engine suffix of CKY is incorrect for a 76 Corvette but is correct for '72.

V0714 indicates the engine was assembled at the Flint, Michigan engine plant (V) on July 14, probably 1972. All Corvette smallblocks were assembled at Flint.

I'm guessing, but I'd say your engine is original and you're reading the numbers incorrectly.

Default Grim -2nd is OK

The second number - 1z37J6S443505
1= Chevy Z= Chevy Model 37= Coupe
J = basic engine 6 = 1976 model s=St Louis
4 = placeholder 43505 = serial of this engine - yours
is the 43505 made at that time.

37= Coupe 67 = converti

L = standard engine J= basic engine

It appears the body is Corvette but your engine is not. 1 is corvette,
and Z is Corvette model. The "VO" on engine pad should be there
but, the VIN on Window post and engine block should be exactly
the same. In other words the Iz37 .... etc should be on your block
also.

The only thing different would be a different engine model - other
than that these codes were used from 1973-1977.

Getting better: 16S443505 decodes as Corvette (1) '76 (6: GM expects you to know the decade) S (plant code for St. Louis) 443505 should be the consecutive unit number for your Corvette.

V0714CKx decodes Flint Engine Assembly Plant (V and correct for a Corvette smallblock) 0714 (calendar date July 14th; date the engine was assembled); CKx could be CKW if your car has a 4 speed or CKX is it's auto. So far, so good. The engine appears to be original.

The L in the VIN indicates the base engine L-48.

Time Build date is probably late July 1976.
