It's got the stock intake and exhaust manifolds both turned upside down, updraft carb and an exhaust stack. I would be willing to bet you could just turn a Fenton or similar dual-carb manifold upside-down as well. The issue will be the exhaust. I'm not sure if you'd have room to run the exhaust in the stock location. | | | | | Joined: Jun 2005 Posts: 1,002 'Bolter | | 'Bolter Joined: Jun 2005 Posts: 1,002 | Sorry, I misread the topic and didn't see "dual". My updraft manifold is a stock single carb.

I believe one of the big GMC sixes (maybe the mid-1940's 426?) had a dual updraft setup. My uncle used a retired GMC road tractor to haul BIG boats from his shop in Goodlettsville Tennessee to Old Hickory lake after he repaired them, back in the mid-1950's.

Cadillac used dual updraft one-barrels on the V-12 and V-16 engines from 1931 through 1937, but of course these were not inline engines.
I have no record of any dual single-barrel updraft manifold used by GM on an inline engine.

Good carburetion is fuelish hot airThe most expensive carburetor is the wrong one you attempt to modify.

This was on an 844 CID inline 6.
Not GM, but closest I have found so far.
