I just bought a Holley 1850-2 carburator (4-brl, 600 cfm) and was wondering if it was possible to convert if from single feed to a dual feed, and if there was any advantage to doing so.

As of now, it has the front inlet drilled out (inlets are on same side as throttle linkage) with a tube running from the front to the back to feed the back. It has the place for the feed in the back, but it hasn't been drilled. I don't have alot of experience with Holley carburators but I could do the work myself (have neccessary tools, skills, etc)

Edit: the carb is built on the Holley 1460 chassis

Yes, you could but I would think it be easier to buy the bowl you need. The main advantage to dual feed carbs are more flow to keep the bowls from running dry at RPM's. Other than that I don't think it worth messing with.

All you would have to do is swap the bowls out from a donor dual feed carb, like a 3310. The 1850s have side drop floats and the dual feed bowls have center drop floats.
I went the other way and had a 780 cfm carb built to look like a 600 with a single feed. This was for an attempt to look original and disguise my 383 as a 327.
I haven't had any problems with lack of gas. Plus, I eliminated the inevitable leaks with those d*** dual feed chrome pipes that seem to be forever out of alignment.

k, thanks for the input. If a single feed carb is enough to feed your built 780cfm/383, it's prolly enough to feed my 600cfm/350. Thanks
