Anyone know where I could get a customized C4 Spec plate for my console? I see plenty of the "spec" plates with the stock information but I have rebuilt my motor and thought is would be cool if I could get a OEM looking plate with my correct motor specs on it.

Thanks in advance....

Even the spec plates you have seen with the stock information are not OEM.
They are all aftermarket. Not sure who actually produces them though.
You might call one of the vendors and see if they can make a custom one for you.

No such thing as an "OEM looking" spec plate.

Try checking out an awards and trophy shop. These stores do all sorts of engraving on brass plates. Some trophies come with plates that have a colored top and when they are engraved, the broze material comes thru as the characters. I have seen black, blue, red, green, yellow plates so you could get something that matches the paint or contrasts with the interior.

You typically pay for the number of lines that are engraved and get a certain number of characters per line. So all you have to do is to come up with what you want on the plaque and the size of the plaque and character fonts.

Ask the store if they have Corvette related images they can use. If they don't, you would have to supply the artwork and it may cost a bunch to have them format it for their equipment.
