Carter Thermoquads ~ 'More General Information'

Bewy- IMHO, with diligent custom work to jetting, metering rods, idle/high speed air bleeds, the 72-up TQ carbs should be able to come close or equal the early CS carbs. The Mopar BB dyno test proved that. It was a list #6922 ? TQ carb if memory serves. It's not difficult to drill/tap for removable air bleeds. When all is said and done, it may just be easier/quicker to just purchase a CS carb to begin with. That's if someone wants to pursue a spreadbore QJet/TQ/etc. type of carb to that extent in the first place. They were cutting edge 1965 carb technology. Great for their time, but let's face it, they've been surpassed. Spreadbores seem to be slowly losing market share, as everyone with an vintage musclecar migrates to a standard square bore Holley style carb. Valuable numbers matching cars are another story. If I had an original late model 1970's 400 or 440 Charger, Cuda, Challenger, it would have the TQ on it, definitely.
