1000 Tq I have used them for 30 years on my 70 stage 1.They run WELL when set up properly.I use the Competition series 1000 TQ.I've got two,just in case. Great carbs.OH !! I met Vic Edelbrock Sr. in Calif.who bought carter carbs from Federal mogul.Said most of the machinery was neglected and junk.They have NO plans to build a thermoquad in the future.So,aftermarket is the only source. :3gears:
Stage2go what are your engine specs is it all stock or do you have different intake single/dual plane cam etc?
I ran a 1000 comp series thermoquad for 24-25 years and LOVED it. I sold it with the engine that came out of my race car. I street drove the car for alot of years. It was rebuilt along time ago by someone in Missouri,in the mid 80's.You can get decent gasmileags on the primaries,then when you open it up,your gone. Mike Nussell
LOLO Go to Tri shield perfomance web site(Jim Weise)and look for my car.It was his first redo and came out well.Car has a "new"455 block(the original motor is on a palet in his garage)TA cam,430 heads,dual plane edelbrock etc. Even stock motors run better with a 1000 TQ,but the real punch is with cam,headers and good flowing heads.
The ThermoQuad has the secondary air door which opens on demand from the motor. It will only open enough to satisfy that demand so it's a very versitile carb and should be fine on your engine. If you don't already have one then they're pretty common in the 850 CFM version. Used to run one on my car, before I went to a Q-Jet and it ETed the same but went 1.5 MPH faster. Dave Berry
I'm a recent Qjet convert. A 1000 cfm TQ was a real kick in the ass compared to the Qjet I had run for 24 or so years! You almost don't notice any difference vs a Qjet except for when you :3gears: I was told by a supposed Carter guru that a 1000 cfm TQ was waaayyy too big for a 455 Buick, and that a non-comp series 800 cfm TQ would be a better fit. "I don't care what Kenne-Bell says", were his words. ou: I would say the biggest downside to the old CS carbs are parts availability. Again, the Carter guru has both strip kits and overhaul kits, but the price for a strip kit was rediculous at $500, and you HAD to buy the overhaul kit with it regardless if you needed it or not. :moonu:
Everything fits under the hood.NOT with the T/A manifold.But I wanted stock appearing and it works. Parts are the single most difficult issue with a CS 1000 TQ.Over the years I have a strip kit and a variety of other parts. On a !000TQ use ,093 for your primary jetting.Of course if you don't have the propoer jets just drill them out.Use a #42 size bit. For the secondaries use .125. No jets again??Drill these with a 1/8" bit.These are the KB set up #'s.I personly run my carb a bit richer due to cam and head flow set up on the dyno.
In my experience on many various engine combo's, only the 80513-1 1000 HPHolley and the dominator series have ever outperformed a 1000 TQ. While tuning and aquiring parts is more challenging, if your up to the task, you will be rewarded with the performance. For Mild builds, a QJ would only be slightly outperformed by a TQ, when you get into larger airflow demands, the bigger carb really shines. Anyone who says "that carb is too big for a 455", is not at all familiar with the airflow velocity of these engines in the intake tract, or the whole train of thought regarding "quality of mixture atomization". It's true that the vast majority of 455 builds don't ingest more than 600-700 cfm of air, the trick is to have a carb sized correctly for that demand, on this particular engine, which provides the best "quality of mixture". And George has a B4B, it's sitting on his SS coded engine, out in the shop.. we had to put a performer on his car, to line up the hood scoops. It all fits nicely under his hood, with the factory air cleaner.
Thank you for your reply Jim, Basically Im trying to get as much information as I can for my build up as to which parts are going to work with each other. Here is a list of what I have maybe you can make a recommendation as to what would work well. This is going into a 4sp car I know I will have to get different gearing for whatever combo I use. 75 block bored 0.030 zero decked forged pistons low compression 1000 thermoquad offenhouser intake single four barrel 67 bigport heads mild port work with kenne-bell roller rockers 1.6 ratio stock exhaust manifolds running into 2 1/2 exhaust Im needing some advice as to which intake and cam I should be looking at getting.
