A friend is building an old pickup into a hot rod. I haven't seen it but one of the things he's doing involves removing the old engine and replacing it with a much larger one. To this end he wants to change the old factory logos
which is about 1/4" thick, with something similar but with the new engine size displayed. Keeping with the older styling motif of simple block letters embedded into the underline bar:
You'll have to envision the polishing but this seems to fill the bill. Same height, width, and thickness as the old one and probably some blind threaded holes in the back for studs. I matched the newer font as it would be easier to machine from a billet.
