The Q-et is very popular in the Pontiac and Buick circles. There are many 11 and 10 second street cars and aome 10 second race cars running around with Q-jets. For a dual purpose car or a high performance street car a Q-jet can't be beat. The small primarys give you great throttle response and good milage, and the large secondarys give you great power when needed. Your best bet is to find a Q-jet expert to send yours to to be rebuilt a set up. I use Cliff Ruggles at Cliff's Q-jet in Ohio. My car hasn't been down the track yet, but should be a totally stock appearing mid to low 11 second car. I run a 245/255 @ .050 cam with a q-jet set up for my set-up and it idles great, has incredible throttle response for this large of a cam, flows 800cfm (it's an older smaller casting, the Q-jets from the 70's can be flowed to around 850-900cfm), and outright screams when it's opened up. Cliff put one of his Q-jet's up agaings a fully prepped Holley 930cfm on a 468 Pontiac race engine a few years ago and out ran the Holley, the performance potential is there. The Q-jet has a bad reputation simply because people in general don't take the time to learn how to properly tune one, then their car runs like crap, and finally they tell everone the Q-jet's are no good. That's an outright fabrication.
Besides, I love it when my car with stock intake, stock exhaust manifolds, Q-jet, points distributor, full exhaust, etc. lines up with a "race car" with screaming open headers, too large cam, big Holley, etc. and he can't catch me!
