Hi.. Looking for a 750-780 4150 Holley, divorced choke, vacuum secondaries, complete, no mods, no stripped threads. A GM OE carb would be nice but not a prerequisite in good condition...
Here you go, Holley List-3310-2, it has a metering plate on the secondary side. Complete with rebuild kit. I doubt it's ever been apart, as the Holley sticker would likely have been removed. I can even provide a chrome air cleaner.
I also have an earlier List-3310-1 with a metering block on the secondary side, with an automatic choke. I can provide photo's of it if you want.
