Chrysler offered a 2 bbl carb on the 225, called it the Super Six.
It did run a wee bit stronger but was a pig on gas compared to the single.
Most owners pushed them hard then complained to us service guys about poor mileage.
But where would we be without innovation and experimentation.
Better to adapt injection than fool with carbs. Much easier to tune, just read the downstream O2. Don.t guess, measure it!
Have fun. Howie
