1964 Engine Pad VIN Stamp

Hi:

I just joined the forum.....and have a question for you all!

I have two '64 Vette Roadsters with factory FI and had a question about the partial VIN stamping on the engine pad of one of the cars. I have had the car since approximately 1978 and always assumed it had the original engine (based on the engine stamping, and the previous owner's testament). The car was not a restored car.....just a driver at that time....and boy, did I have a lot of fun with it back then.....lucky both the car and I survived....but those are stories for another time and place. Anyway, I was looking at the partial VIN stamp today and noticed that the last character (the number "0") had a space between it and the previous character (also the number "0") that was larger than the spacing in the rest of the partial VIN sequence. In addition, the last "0" appeared to be double-stamped, with one of the "0's" being very light, and the other, much clearer. Is this something that occurred very often? Is it due to the nature of hand stamping the partial VIN during the manufacturing process? The engine has never been rebuilt (or decked). I did remove a cylinder head once to replace a blown head gasket....but that is the only work done to the internals as far as I can determine. It still has the standard bore. Thanks in advance!

I've read that original stampings sometimes are not perfect - and you could very well have one.

The point being made in the article was that this was a production environment, and they weren't looking at their work as museum quality - just good enough to get the product out the door.

If energy and enthusiasm were a substitute for experience and expertise, then I could hire my 12 year old to do this job.

Looks real to me. Although the space between the numbers would be unusual, it sure appears real.

Engine pad stamp 4118600 F0513RF

"4" 1964 engine , "118600" last 6 numbers of the VIN ( they were hand stamped with a gang punch and sometimes things just didn't go right on the line causing slips) , "F" engine cast in Saginaw Mich and assembled in Flint Mich , "05" May , "13" 13th of the month , "RF" 375 HP 327 with a manual transmission.

Sometimes there was a punch used that looked like an "I" for the number "1"
If they have a slip and punched it wrong or didn't hit it right they would just give it another smack or repair it. They were making engines to sell and not a work of art.

I hope I didn't lead you down the Garden Path. Bob

1964 FI Block VIN number stamping

Thanks for the input, guys. I appreciate it very much. It had been so long since I looked at the ID pad, at least 25 years, that I didn't recall the space between the "0's" (and the double stamping of the last "0"). I do remember that I painted the pad when I first bought the car in 1978 because it was bare metal and was beginning to rust. I find out now that GM did not paint the pads, so it is additional evidence to me that the pad was likely as it came from the factory. Again, I appreciate the input from all of you.....especially the "pit crew hoss", Dan, who figured out a way to upload my engine pad pic to the forum so all could see it!
