Default Missing Assembly Stamping

So I got the judging book. It says there should be an assembly stamping on the front of the motor by the water pump. I have looked all over that area, I'm pretty sure it's the pad on the passenger side of the water pump, there is no stamp. My two rear stamps are there and seem to be correct. Is it common for late 62 engine to be missing the assembly stamping?

I don't think so.

Is the VIN derivative correct on the pad? Could it be a restamped engine?

Picture would be helpful.

PS- what "2 rear stamps" are you talking about? Do you mean casting numbers?

VIN derivatives were added to the block during the '60 model year; yours should have one. Perhaps the engine has been rebuilt and the decks surfaced. That would most likely remove all the pad info.

vettebuyer yes I meant Casting Numbers. I don't see the Vin or plant code. I'm looking all over around the water pump. The flat pad on the passenger side of it is blank.

Also does anyone know why someone would drill a hole in the vin plate?

They probably mounted some kind of accessory back in the day. Not uncommon to see other holes in the cross frame. Dennis

Beat me to it, that's what I was going to say. That's an early car. Do you have power brakes?

If there's nothing on the pad, then it's been rebuilt and decked at a minimum, or a replacement block.

So the date casting, and engine casting are right. but I don't have a vin stamp or plant stamp. I wanted to build a numbers matching car. Looks like it's going to be a hot rod instead.

The car did not have power brakes. Front rotors were installed, but I have all the original components that were taken off. Without a a vin stamp or plant stamp, it's not worth trying for a correct restoration. Right? Plus I just checked and I can't find a frame stamp. The funny thing is this car has green paint which are consistent for AO body. I know that shouldn't be for a 63. Looks like the guy I'm building the car for got duped.

The stamp pad is on the front of the block on the passenger side.

Cars can certainly achieve NCRS National Top Flight with a blank engine pad.

He was duped if he was told the car was numbers matching, although if he bought it under those parameters and didn't look at the pad to see it was blank, he bears some responsibility.

While the car cannot be an engine numbers match car without restamping it (and I don't know what the pad/broach marks look like), the casting date is OK and it's an 870 block, which is correct for a '63. I do not agree that it has to be a NM car to be worthy of a stock correct restoration rather than hot rodding it up, especially with a motor that's as era / date correct as that one.

So is the body off or you are just having trouble trying to see a frame stamp upside down with a mirror?

There are more problems then the pad, lol. The trans is wrong. It's an M21, from what I'm reading it should be a borg warner. The rear end does not have a date code and is 64. His last project manager did no research and has spent 10k, mostly on wrong interior and parts. The car was bought painted, it has since been chipped and stress cracks in the rear from the shim being put in the wrong place when the body was put back on. the body was taken off and the whole underneath was painted black. So it's either strip it down and start over, or at least build a nice running good looking vette. Maybe this guy can get his money back. I don't know. This is my first full restoration. I have no fear of doing the work, but the cost might not be worth it. Any advice is appreciated. One thing I have learned in the last few weeks is every time I search for an answer, I end up on this sight, lol. I have the judging book, I'm still waiting on the assembly manuals and Nolan Ryan book.

So the guy he took with him to buy the car not only missed the pad not being stamped, but it had 250 heads on it, and it was being presented as a 340 horse numbers correct car. The body is on the car, but do not see any numbers on the frame. I'm getting ready to check the book and see where the numbers were in 64. If I don't see them there I am going to start sanding the frame back down. maybe when they painted it they went very thick in that area. I'm looking on the top of the frame above the drivers side rear tire. The whole width of the tire.

Frame VIN derivative was stamped in two places on the drivers side frame rail at the top. Perhaps someone can post up a pic for you. They ARE in the archives if you search, but we should be able to get you a pic later today or tomorrow.

Heavy paint could cover the stampings, since they are not that deep.
