The Cylinder head casting code is one of the best ways to identify a cylinder head. It is usually found on the top of the head in between two valves and the rocker arm studs...disclaimer: all I did was paste that from Camaro.com/VIN
Did you check the bell housing?
the engine vin is located on a pad on the front of the block just below the head. there should be a 5 or 6 digit number with a 2 or 3 letter code, the 6 digits should match the last 6 of the vin on the dash. also on the back of the engine is the block casting # , but it has nothing to do with the vin & thats located on top where the engine and tranny meet.
Something just occurred to me. Do you mean the VIN on the dash by the windshield is missing? If so you may be driving a stolen car. They should be there or something is really,really off the rails here
Thanks to everyone that answered... The car was stolen didn't know that till I changed the title over it was never mentioned to me and I foolishly never asked.. The state Oklahoma issues a vin number to a car after it has been cleared so then I'm left with the problem of finding out what the original vin number is I still haven't had any luck I would love to find out because according to everything I have read my 87 Iroc z-28 was never produced with a 5- speed transmission and a 5.7 v8 but here it sits in my driveway.... Pulling what hair I have left.... Lol
Redpepr. there has GOT to be a way to find out, especially if it was stolen sometime in the past and 'chopped'. If the OK DMV can't/won't help you, seems to me the cops can, somewhere there is a stolen car report. Even if it was not stolen in OK They AND the manufacturers have a data base that can trace it either from the sticker on the door (probably gone) , see if GM will help you... it's difficult to impossible if the engine and/or transmission has been swapped. There are VIN and ID numbers all over the car, maybe the thief missed something, although the theft rings are pretty good at what they do, but for precisely that reason there are ID/VIN numbers in places not known to the public, hidden. When I buy a used car, and I have bought dozens in my 58 years, it never occurred to me to ask if it was ever stolen. For one, the seller probably wouldn't know, and if he/she did know something they sure as f*** wouldn't tell you. If you can get a carfax somehow would be great. I don't want to sound like a commercial for carfax but they are the best thing since sliced bread. It will tell you where it was bought new and the original owner maybe, just maybe, will have some paperwork. Good luck my friend
