Thermoquad vs Quadrajet

Jeff Lee · 12-17-2009, 07:28 PM

I was under the impression all Q-Jets were 750 CFM except those with only one ring around the booster which were 800 CFM. The 800 was a specialty carb as used on 455 HO Pontiac, SD 455 and probably a few others. Correct or wrong?

On the T-Quad, it's 750, 800 & 1000. Basically small block, big block and motor home big block. Again, correct or wrong? Wasn't there a red bowl race T-Quad @ 1100 or 1200 CFM?
