Default Piecing together a 96 LT4 VIN Question

Hi,

I have a used LT4 engine/trans with the following partial VIN stamped
on the top rear drivers side part of the block. It reads:

1T5101377

I went to the idavette page and tried creating the following complete
VINS of which none validated on Carfax. ( I have someone wanting to buy the motor, but they want some mileage verification from the car it came from.)

I tried the following VINS of which none worked. I guess I am doing something wrong.

1G1YY3251T5101377 -- convert LT4
1G1YY2251T5101377 -- hardtop LT4
1G1YY32P1T5101377 -- etc..
1G1YY22P1T5101377
1G1YY32P7T5101377
1G1YY22P7T5101377
1G1YY3257T5101377
1G1YY2257T5101377

The block definitely reads 1T5101377 but I was trying
to replace the first "1" with a 7 to see if it worked. I'd
really appreciate it if someone can come up with the
VIN, I'm not sure if it was a coupe or convert, but I'd
guess a Coupe.

Thanks for your time,
Sinclair

Thanks very much for the help. I will try to formulate the 96 Vin using the information you gave.

the 1G1YY will be the same for all VIN in 1996.

The 6th digit is "3" for convertible and "2" for coupe

8th digit is "P" for LT1 and "5" for LT4

9th is a security digit and varies

It appears that you have tried every combination and come up with zilch.

:confused:

Thanks I managed to luck out and figure out the VIN. It is:

1G1YY2252T5101377 - which is a 96 LT4 Coupe.

The "2" before the T does not match the "1T5101377" stamped on the block.
I decided to try every digit/character as the check digit and luckily on the
second try the "2" worked. My problem was thinking the digit on the block
before the T was the check digit which it wasn't in this case.

Anyhow I purchased the Car Fax report and it matched what I was told about
the car the engine came out of and location/mileage etc..

Thanks for everyones help...I was going to give up until I got the first response verifying what VIN parts change/don't change etc..

Thanks again!

I guess if you think about it, it would be a logistical nightmare (from a manufacturing standpoint) to put the check digit on the engine. You have no idea which car that engine is going to wind up in.

Anyways, glad you figured it out. :cheers:
