Hello, I am Interested in a 67 GS 400. I don't have access to see the car but I am trying to get the numbers off the block to see if it is matching numbers car. The guy found the NR (67 400) on the block but can't find the numbers that should match the vin.. I thought they should be on the passenger's side of the motor where the size and year code is but he can't find any other numbers on the block. Could this be a factory replacement motor? I thought there would be RB if it is a replacement block. The NR is between cylinders 2 and 4 and I thought the other coad was between 6 and 8. Can anyone help? I'm not interested in the car if it isn't numbers matching so I would like to find out this information. Any help is greatly appreciated.
Where was the car built? From what I’ve seen, only a ‘67 from Flint will have a VIN stamped on the block. I have two ‘67 GS400s built at Kansas City plant that have the original engines and a couple of spare ‘67 NR engines and they only have the NR code between #2 & 4, no VIN. The VINs that I’ve seen stamped on the Flint cars was between #6 & 8 just as you mentioned and as shown in the service manual.
The car I am looking at was built in Fremont CA so it won't have the numbers that match the Vin is what I am reading. Thanks
I’ve never seen a ‘67 from Fremont with a VIN. About 15+ years ago I inspected a very original ‘67 GS400 for someone and it had no VIN, only the NR code. It was at that point that I started paying attention and noticed that no Fremont or Kansas City car had it. There also will not be a VIN on the transmission.
I could be wrong, but I'd be shocked if Flint was the only plant stamping vins. I bet if you had a freshly cleaned bare 67 block, you'd be able to find it. I'd certainly check the front face on both the left and right sides. Different plants stamped in different locations was GM history, for instance I saw a 454 chev with the vin stamped on the bottom side near the oil filter (which is in the back), and the assembly manual showed nowhere near that location. The excuse I heard is the engines were moved overhead and stamped just prior to lowering... The vins where used for tracing stolen parts, chop shops, etc, and if a plant didn't have the ability to stamp, they would not have been able to complete final assembly.
I googled it, fed mandate to stamp blocks was Jan 1 1968. So possibly Fremont did not, but I'd bet against it.
