I have had a few. I had a Dart Sport 340 that came to me with no motor or transmission. I slipped in a 360 and added a ThermoQuad to maintain some semblance of a factory appearance. I had it rebuilt by a local guy. It did not want to cold start without several shots of ether but would restart just fine when warm.
Just for the hell of it, I added a factory choke. I've never used a choke in any of the Holley carburetors so I did not expect an improvement.
That car started easily every time after that. No pump of the pedal, just crank it and it would start within 3-5 seconds most of the time. ALL the other times I used these carburetors, I ran them without a choke and always blamed the hard starting on fuel evaporation or on the carburetor itself. For years I thought these carburetors were troublesome until that time I added the choke.
I had one on my 75 Power Wagon but switched to a Holley for simplicity. The truck starts great in any weather with the Holley but regardless, I was impressed with the Carter after learning what I was doing wrong for so long.

Good stuff FRANKENberry ! ... A choke is a MUST HAVE on any type is streeter BESTEST combo is an alum intake with the choke well. It has been A BUNCH OF YEARS since I've even SEEN a TQ ! New life down here .. I've tried finding a warehouse type building PRICED REASONABLY .. With no luck. I have my 62 and two gasser Motörhomes that I have TQs on ....I kind of miss tweaking that stuff .. Both for performance and mpg

I'm running two of them, one on an all original low miles '79 LRE Truck, and the other is on a '79 Warlock II Powerwagon restored to original+ condition, so I really am forced to love them...and they're not bad.
For crank it up, get on the road and go, hard to beat fuel injection IMO. twocents

Still have 1 on my 440 powered motorhome. Taking it up deer hunting in a few weeks, and steelhead fishing. Great carb, hard to beat.

Who makes this Thermoquad thing and is it only used on Mopars?

Ford used a couple in O.E.M. applications as did International, but most were found on Mopars

I just sold my 85 Crew cab a month ago. I had an aftermarket Thermoquad on that for the last 8 years. Drove it every day summer and winter. It will get down to -20 here in the winter. Never had a problem.

I have one on my old motor home. Something went wrong, float stuck????? It caused a fire once, burned everything under the dog house. Replaced the burnt wiring and plug wires, never had another problem.


it's ok to butt heads, just don't do it with a butthead

I'll tell you, I loved the one I ran on my old 340 bracket car. I could soften the hit of the secondaries when the jet cars killed the starting line, and I could adjust for Calgary's wild air density changes with a simple turn of a screw (don't remember what it was, but it was accessed with a long screw driver via a hole near the carb stud.)
Granted, I've only dabbled with jet changes on my Claw. But, along with being far more sensitive to air changes than the Holley-type carbs seem, the T-Quad was also very responsive to adjustments. When I got the hang of it, I really managed to tweak the 60' time by fine-tuning the baseline of the secondary air door. I was running a set of M/T 8x26 bias slicks, and even my torque challenged 340 could over power those tires if the secondaries hit too hard on a good starting line.
It helped that we got 4 time trials back then, too.

I still have a few.

When I run the single four the T-Q gets the nod, currently on a pair of AFB's

I do remember everyone complaining about them years ago. Saw lots of them end up in the trash.

I have one on an 84 Ram plow truck. I'd had it for a number of years and wasn't too crazy about the carb, although in fairness the truck sits an awful lot.

A consistent cold start problem finally prompted me to take it off and go through it. Turned out a small bowl had separated from the rest of the plastic body; the glue had let go. I don't know how it ran at all like that.

Certainly explained why the oil would get to smelling bad so quickly. I was changing the oil in it a lot!

Cleaned it up, JB welded the bowl back in place and once I figured out the location of two small o rings it turned out to be pretty much trouble free.

Still have one sitting on top of my 440. Once you get the hang of bending linkages to dial them in they run great. With the choke setup as per my factory service manual she fired right up easy even on a cool morning, let it run for 20 seconds, kick it down and away I went. Next best thing to fuel injection.

I had a TQ on the 400 in my '71. Loved it. It got worn out and was leaking fuel through the shaft bushings. So, I switched it to an Edelbrock carb and new manifold. The Edelbrock isn't even in the same ballpark as a good running TQ. Eventually, I'll do what I should have done in the first place and send my TQ to Harms and get it back on the engine.

i like 'em too. i have quite a collection, and buy real nasty ones at the swaps for $5-10 for parts. e-bag prices for new jets and rods are way up there now. a long time before i retired, i wrote several programs for a hardinge CNC, then ran a batch of jets and metering rods. they turned out great !

On the 74 Duster360 I had, the TQ was awesome !!! Ran great, great mileage too !!! The 77 New Yorker I had, had 440 with Lean burn, which of course I trashed and put reg. electronic ignition and a TQ that I rebuilt, from a 75 440 . . . just had to pump it twice, setting the choke when cold, and started right up and when it came off the choke (like a minute or two), would run perfect with no stumbling ! Love those carbs !! Just have to understand you rebuild them in sequence . . .
