9002S Thermoquad carb

Calling all Thermoquad experts:

I have a lead for a 9002S Thermoquad carb for only $25. It is a little rough but moves freely and still looks functional.

I tried doing some research on this and all I've come up with is that it is for for a 75-76? 360 AT.

I have a 360 with about 9.7:1 compression and .509 INT/.522 EXH, lift hyd. roller cam
Stock 308 heads with mild work done, Hooker comp headers and an air-gap intake manifold.
I currently have a Carter AFB 625 CFM carb on it right now.

When it comes to Carter AFB/Edelbrock performer series carbs I know quite a bit about them.
I have rebuilt 3 AFB's and 1 Edel. performer. I made one attempt to rebuild a Quadrajet M4ME (or M4MC), unsuccessfully.

Are these a good series of Thermoquads to work on? I don't have much experience with these carbs. I did some tuning on a Thermoquad 18 years ago on my 1984 Ramcharger I used to own.
