If there is anyone looking for this or can Identify what it came out of send me a pm please.


That is the engine serial number.

It was stamped well before it was mated to a car.

To match it to a VIN, check & post the number on the passenger side of the block, stamped on a pad down low.

That will indicate the partial VIN for the actual car it was actually assigned to.

Thank you.
I was thinking the number stamped on the front of the block was the same as the number on the rail. Sorry its been awhile! I was going by pictures I have on the front of the block and I didn't take any of the number on the pan rail. Too lazy to go dig it out last night! So now we know what it came out of just have to find out if the car still exists ?
Thanks again
