Big Tuna
Too Much Power!
Hello my fellow motorheads. I just wanted to throw this out here to let everyone know that I have vast experience and knowledge with rebuilding, tuning, and adjusting the Carter Thermo-Quad. I have been using/tuning TQ's for better part of 20 years now and I know them inside and out. I have taken ones that were left for dead and turned them into great runners. So, if you own a classic Mopar/IHC that has a Thermo-Quad, and you are looking for help/advice, I will gladly provide my assistance to fellow AKers. Purely complimentary.
A little History: TQ's began life as a race carb in 1969, then the first factory iteration to house the TQ was the 1971 Dodge Demon 340. My brother had a black one with a 4 Speed on the floor when I was little. The 340 TQ equipped Demon had a faster Lap time than the mighty 440 Six pack! '72 saw them being implemented on all the 440 Big Blocks, and the HP 360's. The center body was a unique "phenolic resin" which had a particular advantage for keeping fuel cooler for better atomization. There were many different calibration ratios, and two different primary throttle bore sizes, the smaller 1 & 3/16" was used on the small blocks, while the larger primary 1 & 1/4" was reserved for big blocks and HP applications. Many have called the center body "plastic" which in part, it is, but that is a rather crude representation of it, since it is much tougher than ordinary plastic. It is Fiberglass re-inforced to add strength. Through the years the TQ was used and abused, and suffered it's share of mishandling by those who were unfamiliar with them. the final year a Thermo-Quad was available on a production vehicle was 1985, and by that time it had sealed Idle mixture screws, and was not tuner friendly.

ara: I guess I shouldn't say that or I'll jinx myself, huh?
