Hoffman, check that number again..I found a 7045214 Quadrajet that was originally on a 75-77 Chevy / GMC (3/4 or 1 ton) non-Cal emmissions heavy duty truck 350 cu. in. motor. From what I could find in a Delco Carb catalogue, when GM went to the 8 digit carb id numbers, they started at 17056*** and that was for the 1975 model year. You may have a marine carb or some other special off road piece, I checked all the GM divisions and could not find any 17045***.
