Default Matching numbered Corvette C3?

Being a car enthusiast and a classic car collector, i'm really interested to know if my newly purchased corvette has the original engine from factory.

I know its ironic buying the car without knowing from beforehand, but these Vette's are pretty rare on our island.

Can anyone confirm if I have the original engine in my Vette? And can anyone decode my Vin number?

Chassis Vin number 1Z37L5416XXX
Engine Number: V1111CLA1754


Thanks guys.

As indicated on its logbook, it's a 1977. Automatic transmission.

No. There should be no 1754 following the suffix code. The VIN you have posted is for a 75, not a 77. CLA was not available for the 75 model year. It was available for the 77s.

Check the VIN on the driver's windshield post and do not trust the "log book." If you have a 75, it has the wrong engine. If you have a 77, the VIN you posted is incorrect.

Ok so I discarded the information on the logbook and checked the car numbers. The following information is taken from the original sticker which is affixed on the driver side door jam. The chassis number is as follows:

1237L7S4165**

Date:
12/76

GVWR
415BLB

GAWRFRT
1898LB


I'm starting to think that the workers at the registration office need to get their eyes checked!


Can anyone properly decode the above information and state wheter the engine belongs to the car?

It's 1Z37L7S4165xxx; it's the VIN number for a 1977 Corvette and not technically a chassis number. #165xx was assembled in December, 1976.

...Engine Number: V1111CLA1754...
V1111CLA is a base engine L-48 with automatic transmission assembled on November 11 at Flint (V). There should be no 1754 following this stamp.

Next to that number on the engine pad should be the VIN derivitive of the Corvette the engine was originally installed in at St. Louis.

No disrespect, but as the owner, you should be confirming these numbers and not relying on the DMV folks.

My guess is that the engine is original for your car, but you need the VIN derivitive from the engine pad to confirm that.

Congrats on the 77.

Post a picture of the pad. Strictly speaking the numbers do not 'match' as the 1754 does not seem to be any part of your VIN sequence.
