Polarizing- yeah

I think the TQ was probably the highest point in the evolution of the carburetor. If its working right, it is simply amazing in how it can adapt to anything from a 318 to a 440 without you needing to turn a single screw. Yes, its better if you do tweak the idle mix and the secondary air-door tension, but it really works fine even if you don't.

That said, those paint-can sized secondaries are big enough for one TQ to feed two slant-sixes. The air-door never even fully opens on a 318.

I have two problems with all the TQs I've seen: first and foremost is the morons who worked on them before me. I've never had one fail from anything other than abuse during a rebuild. Second is the X-section O-rings at the base of the main jet wells which do eventually start to leak, causing the morons from item #1 to even open the carb in the first place.

Definitely also on trucks (360s more often than 318s in that app). Chrysler switched to the Q-jet after the TQ was no longer available, so your "through 1984" doesn't quite compute- it would have been through 1989 and STARTING in 85 or thereabout. It was all TQ before that.

Too many people who were born on third base actually believe they've hit a triple.

Well, I have one Carter Thermoquad in my garage, late sixties or early seventies, I'm not sure.
When I stripped the Diplomat cop car a few years ago (which I bought non-running for $25 dollars!), it had a thermoquad on top of it's 318. I used this carb as a core for the Carter bbd I bought from O'Reilly's.
I agree on these carbs being "polarizing".

The scary thing is that I've known you long enough that I can almost do that...
