Engine Pad

[Bob P.]

I'm looking to get a few opinions on he authenticity on the engine pad on this car. The biggest question I have is the broach marks. The actual number/letter stamping I think looks pretty good, but would like to get any comments on it as well. The problem with the broach marks is that they seem to very with different light or if the light is coming from different angles. Any opinions would be appreciated. Thanks

Any opinions would be appreciated. Thanks

Higher resolution photos would help. I can barely see marks in a couple of the photos you provide, but the resolution is poor enough that I can't tell if they're actually straight or not. If you can get better ones it sure would help.

Re: Engine Pad

Attached are the highest resolution photos I have at the time. As you will see, light or the lack of light has a big impact on determining the existence of broach marks! Let me know what you think.

Re: Engine Pad

Bob,
I don't see any broach marks.
It looks like the surface has rusted or pitted pretty badly as the pits are also in the stamped numbers.

Re: Engine Pad

Any opinion on the stamping numbers/letters? If you look at the pictures I posted earlier, the pictures that are at an angle that create lighting going across the pad instead of directly down on the pad I think there appears to be some broach marks? It is really hard to get a picture of the entire pad at this angle because fuel lines and other things in the way.

Even after blowing up the high resolution pics., there are no broach marks.

Re: Engine Pad

What I don't understand is how the stamping could look correct, but the broach marks aren't there? Any explanations?

IMO, the pad looks like it's been shot blasted at the machine shop and could have been lightly decked. The numbers look original to me but I'm no expert.

I agree with Tim about the shot blast or some type of sand blasting.

No doubt shot peened. A common engine rebuilders process for cleaning in place of solvent. Not a good thing for engine pads.

Re: Engine Pad

The only thing bothering me about this pad is the fact that the numbers are extremely deep even though the pad has been either sanded and or shot peened. After such rough treatment the numbers are usually shallow and even some are faint! Leads me to believe that this pad has been stamped HARD! Just a few thoughts!
If I were looking to pay big money for this Corvette I would get on my runnning shoes!

Agree with JR - RUN, Forrest - RUN!

BTW - when I blew the pictures up it appeared like there were some faint tracings of some numbers in the background! Could be the angle of the picture, but definitely hinkey stamp pad.

Re: Engine Pad

surface has been blasted with some sort of media. it would be worth it to get the owner to have Al Grenning certify

Re: Engine Pad

A little food for thought.
If you look at the top of the water pump where it meets the stamp pad, the pump looks as if it were give the same treatment the pad was.

This is a little troubling.
