Stop in for a cup of coffee

I think the edge rocks use the AVS spreadbore style. I really don’t want to buy a new carb when I have this brand new Holley already.

Reading on the poly Facebook page that some people had to use a Rochester to Holley adapter to get things to line up. Something about bore centers.

Actually don't see how this will work.

Its made to use the early WCFB pattern to either of the later patterns.
Seems like there's really not enough room between the AFB and the Holley 4150/Edelbrock...
Not much support for the washer and nut the other way ... maybe how the PO cracked it.
