71 4dr Dart 318 w 4bbl

I did not intend to imply that the TQ carb lacked in performance. I know from experience that they do quite well. I've had 4 of them on different cars in past years. One of them I ran for more than a year before it succumbed to the one of the most common problems with them, a crack in the lower part of the plastic body. Repairing it was not cost effective.
So I ask the question why would a guy want to take the time to find a TQ, in good condition? It has been 30 years since the Thermoquad was manufactured.
