Other than by serial number, is there anyway to identify the larger cfm (larger than the 750 cfm QJets) carbs? I.e.: the 800 to 850 cfm.
Rochester Quadrajet Carbureters (?)
- Thread starter chromebumpers
- Start date

Its debatable some 800 cfm claimed models.
Never seen actual Rochester Engineering Tested results on later claimed Pontiac 800 cfm models.
I go by Doug Roe.
He was the Rochester Q-jet Engineer.
1973-74 SD-455
1970-71 Buick GS STAGE 1 455

"One test is worth a thousand expert opinions."
I had one that came on a 267 SBC that someone gave to me.
A Thermoquad, and it looks different than the regular quadrajets and Carter AFBs.
If your quadrajet has the largest factory bores and the throttle plates open to full 90 degrees, you have 800 cfm.
Like Brian said, it's in Doug Roe's book. Another good source is www.cliffshighperformance.com

Yes - I remember that. I have a few large bore carbs, one is a rare '70 Hurst 455, a Buick Stage I and I forget the others.

Is there a thread on this TT?
There is a different supply and demand economy throughout the world. American muscle is endless here, not so much in Europe. Looks like as much as 30% higher in some countries.
Last time I reached in my pockets my hand got scared and lost its so deep in there!

If you can find a Buyer for the Hurst 455 W30 Carb its the most desriable.
There is No Power Valve used.
Set up like a True Drag Race Holley.
Be nice if it was SD455 800 Cfm Value.
Maybe $3,000 cash for the 1970 W30 455 carb.

Price it high and none will call.

No there isn't. But the TT as of this weekend is on the block. I realized that my kids are soon driving-age and will never be able to drive the TT. Nor would I allow it. It is too dangerous. So it is time to let her go. My plan is to replace the venerable TT with an early C3 'vette. Not sure how this came up here...
I met the Clifford guys at SEMA a while back... I was tempted to stick with my 250L6 but they weren't convincing enough when it cam to performance claims. I liked their logo 6=8. When I met them at SEMA, they had just undergone some very big reshuffling or personnel.
Instead, I got an SBC400 and my 250L6 was donnated to some fellow in the UK ;-)
