Carter Thermoquad model 9801

Getting to know a TQ takes a little effort in the learnig curve. You will have to make sure everything is adjusted and set up correctly. Tuning parts are hard to find though not impossible.

Depending on the cam inside the engine, the carb may be OK. The TQ you have is a stock replacement carb. The primaries are small, so you may feel a lack of throttle response (In power terms, not driveabilty) over what you have now.

I have one on my 400, which is otherwise dead stock (1978 unit) except the Holley street Dominator intake and the Headman headers.
