hi all.. ive been looking all over the place for a vacuum diagram of a holley 2280 2 barrel off the super six and i cant seem to find one anywhere. the carter bbd is simple to find but for some reason i cant find one for the holley. if anyone has one please let me know or at least can tell me where the hoses go. thanks a bunch guys

Are you talking about the choke unloader? (The little vacuuum can that moderates how the choke plate pulls oen?)

I think Niehoff FS1034, or GP sorenson 779180 is another.

Remember the Holley 2280 is for the 1978+ 318 equipped vehicle (meant as a replacement for the BBD, but never offered stock on a super six)...

This carburator/parts can be found by selecting a 1978 Dodge Aspen w/318 at your auto parts store for lookup or you can use tag number R-7990A as another reference point...

good luck,

duster i need the full vacuum diagram for all the little "nipples" on the 2280 so i can see what hoses go where and what doesnt need a hose on it.

The Holley 2280 isn't original to that car so the Carter vacuum diagram is the only one you're going to find. As the 2280 was meant to replace the BBD I would expect (hope?) the connections to be in similar locations.

ok guys i found a diagram that apparently doctor dodge wrote on yahoo pictures keywords holley 2280 if anyone else needs one. i have 2 questions now.. my car has a vacuum advance on the dist. and according to the diagram there isnt a nipple for the advance to go so where should i put the vacuum advance hose? my other question is what exactly does a "bowl vent" do? thanks for ur replies guys

The vacuum advance will connect to the "To Ported for System" nipple shown in this view.

For the bowl vent, leave it open, it is a good idea to put a filter on it to keep any dust out.
