The ECG-6 is a '56 Ford car 272 Y-Block carb. The ECW -6 is a '56 Ford truck 272 carb. Both were the largest air flow size ever put on a Y-Block from the factory. Pretty sure around 250 CFM. They had the 1 1/16" venturi's and larger throttle bores. The ECW carb will have a different top because of the air cleaner mounting.
To me, an excellent choice for on top of the blower if you want the nostalgic Holley 94 look.

I am running a stock Ford EBU carb (1" venturi's) on a '55 with bored out 292 and stock load-o-matic distributor. While the performance of the EBU may possibly be the worst of all carbs of this type, my fuel delivery system kicks butt. The EBU and its Holley equivalent, the 2100 were only used on the '54, 239 and '55 Ford 272 Y-blocks. I have had and run a Holley 2210 (same thing as ECG having 1-1/16" venturi's) using '56 intake manifold and air-cleaner. I never noticed any better performance in the 2100 than the EBU, but the engine ate more gas with the 2100. My two cents; either of these carbs can give great performance if they are properly cleaned and rebuilt with good ethanol-compatible gasket sets AND that the load-o-matic distributor is in good condition with a properly functioning vacuum advance.
My biggest complaint about all these types of carb designs is that the accelerator pump check ball always leaks all the gas out of the float bowl after a few days of sitting. So you either need to manually prime the carb to start, or install an auxillary fuel pump just for the purpose of priming the carb.
Don't make the mistake of mixing different carbs on a tri-power as you will not be able to get an air-cleaner to fit. The EBU/2100 has the smallest throat diameter. The ECG/2110 has a bigger throat.
