I have a quadrojet, which I was told was the original, but if I'm reading the code stamping correctly, it's not.

I saw two codes (one on a circular pressed piece on the side) that had 7037202 and HO or HD with I believe M6 - and then one pressed into the metal on the back side that was 7032750

I googled 7037202 and from the results it looks like it was a '67 era carb for a 327 or 350 (I have a 400). Thing is, on the base is a stamping that I think is the date code, which reads 0318 (or 31st day of 68).
