Mine came with a ThermoQuad already, so that should help. I seem to remember my grandfather saying he got about 10 mpg, but he never drove over 45. LOL
You’re lucky. Mine had the Holley 2245. I was lucky enough to find an ‘83 B150 in the junkyard with the 4BBL intake and ThermoQuad, but it took three ThermoQuads to make the one I wanted. Mine now has the altitude compensator on it. In fact, the only thing that is from the original ‘83 is the phenolic body, the rest is from a ‘74 340 engine car.
Dang it, I'm getting sucked back in ...
I'm fairly sure the 383 in my '66 Polara had a factory original 2245 on it. Never had to mess with it. Seemed to do okay.
Removed all the tread, down to the corda, on two rear tires in a matter of weeks. Contributed to my first speeding ticket, officially 73 in a 30, half a block from the stoplight. (Cop was a friend who didn't know I had a different vehicle ... had already called it in so he had to give me something ... radar was flashing a number over 90.)
If I behaved myself, holding it down to 50-60 mph, I got over 30 mpg. Of course, those where the days of better leaded gas, which probably had a lot to do with the gas mileage.
Bottom line: most carburetors on the market will do well if they're reasonably fresh and well tuned. The rest is personal preference.
