It does have its restrictions though. If you are running a fairly healthy cam profile that has a tendency to limit your vacuum level, the Q-jet power piston spring needs to be selected carefully- just as you would do a Holley power valve. Several companies make different power piston springs for this and jets and metering rods are also available. | It does have its restrictions though.

| − | With it's centrally located fuel bowl and the aforementioned power piston, the Quadrajet is a great all-'round carb for street machines and if your doing a restoration on a 60's or 70's muscle car, the carb just can't be beaten. Once tuned, it stays that way, with very little need for upgrades or maintenance. It's true, that it is a little more difficult to rebuild because of it's varied tuning characteristics, but that is the beauty of the beast, you can make it work on just about any engine design. With it's small primaries, you can cruise and get reasonable fuel mileage, or you can kick in those monster secondaries, forget about fuel mileage,and fly. | + | With it's centrally located fuel bowl and the aforementioned power piston, the Quadrajet is a great all-'round carb for street machines and if your doing a restoration on a 60's or 70's muscle car, the carb just can't be beaten.

Several companies make everything you need to tune the Q-jet to fit your needs, or you can buy a new carb from Edelbrock. [http://www.jetchip.com/ Jet Performance] also sells Q-jets in several stages to meet your application. If your running a nice little street engine with a little thump, you can't find a better carb, but if your getting into that monster pro street stuff, you need to look at carburetors that can handle the needs of these engines and/or have a very good understanding of the tuning requirements needed to allow the Q-jet to work well under these conditions. |
