Holley Double Pumper Question(s)
-7 is the revision
C is the dichromate finish
The number underneath is the date code.
For example, from the 2018 catalog.
So either the current revision changed meter blocks etc, or the photo is wrong because the marketing staff is clueless.
My bet is the latter :(
The website info says its an dichromated aluminum body carb with straight boosters. I'm not aware of dichromate finish for aluminum casting as those are usually anodized. Second, the website photo shows downleg boosters. Third there is no mention of four corner idle even though the website photo shows it.
Good guess but not correct.
