I have an old Holley 750 DP. After cleaning it, it still looks old. Is there any way to clean it up? Maybe a paint, or sandblasting (that could wreck the venturiis), or a chemical dip (again, wrecking the venturiis), I don't know. I was thinking of running a scotch brite pad over it, but that will take forever. The rest of the engine will be painted and new chrome, I'd just hate to put a skanky looking atomizer on top of it all. It has chrome accessories (pressure gauge, fuel inlet splitter, etc.) and they look juxtaposed against an oxidized carb body.
