I recently got this 1963 GT Hawk. It has a tiny Carter 4947S in the 289. Assume this is not stock based on what I have read. Seem to run fine with it if a little underpowered. Anyone have experience with these carbs? Are they any good? Any recommendations if I were to change? I have seen the posts saying that the 4 barrel intakes (converted from stock 2-barrel manifold) with the 500 cfm Edelbrocks are good. Thanks

No, the Carter is not OEM; that would be a Stromberg WW. Probably there's not much difference in performance.
Yes, the late 2-bbl intake and the 4-bbl begin life as the same casting. Only the final machining of the carb mounting base differs. However, it's not an easy conversion at home unless one has a mill and much experience using it. Jeff Rice has a shelf full already converted.
Maybe, notice how often you run the revs above 3500 RPM. Below that, the 2-bbl is about as strong.

Of course most of us have tried and proven the Edelbrock Auto Choke Performer 1403, 500CFM to be very good and the AVS 1900 Series and Thunder 1800 Series Better, but there is nothing wrong other than the Manual Choke with that Carter, IF you can find out if the CFM's are close enough for a 2 Barrel.
Does the Base have the correct 3/8" Vacuum Tube for the '64 Type PCV System?StudeRich

There is no vacuum there, air goes in and out of the ends of ONE Tube and is heated to go to the Automatic Choke that you do not have.
That large Hose on the right of the Carb. may be going to the Dist. Vacuum Advance or the Crankcase PCV Valve and Crankcase, but it is ABOVE the Throttle Plate not in the lower Base as a PCV Fitting should.
I know nothing about this Carb. or what Car it belongs on, certainly not a Studebaker.StudeRich

You only operate off the 4bbl primary circuit until you press harder on the accellerator pedal.
The engine will run many happy miles with the small 2bbl on it.
A good 4bbl will perk it up and make it better during freeway jaunts.
You can, of course, get an AFB ready cast iron 4bbl intake from me, or.. Studebaker International has some in stock, too.
My only suggestion is that if you do go to the 4bbl intake and carb...Get the manifold install kit. Makes it an easy upgrade to do.
