Yep. The same basic 750-800 cfm Qjet was installed on 231 V6 buicks, and 135-hp Olds 307s, all the way up to the 455s and Caddy 500s.Rat Rod said:Q-Jet for me all the way. That is all I use. Most dudes don't know that the q-jet is almost an auto carb, it will adjust to almost any vacuum created by the engine and perform flawlessly over a wide range engine demands. As I said the q-jet is the only carb you can install and get years and years of flawless service.
When you put it in that sense Curtis, some other brand carbs can come close. Mainly the ones with the metering rods like Carter AFB, AVS, and the "THERMOQUADDDDDDDDD" (My personal favorite after the QJet of course). If I am not mistaken, Rochester provided 3 taper rods for the primaries on "some" QJets, now can you imagine 3 different fuel curves and specific vacuum points from a carburetor? Up to 2 tapers for the secondaries! How the tar can you possibly go wrong with this carb?!curtis73 said:+1 for the Qjet. The tests have been done, no other carb, factory or aftermarket is more accurate at metering than a Qjet.... properly set up of course. Small primaries for killer throttle response, typically less fuel consumption than other carbs.
I'm convinced that the only reason NOT to use a Qjet on the street or street/strip application is because the user is afraid of Qjets or think they are tough to tune. Otherwise I think they are a far superior carb as far as metering goes. Don't get me wrong... all the major carbs you find on engines are fine pieces and can be tuned for identical power and drivability, but if you can get better throttle response and mileage, why not ?
