Quadra-Jet use on Fords
lightning boy:
Anyone know the history on why some Fords used the Q-Jet?
I know some Gran Torinos used it. and maybe some big block Mustangs. Seems odd because their use was so limited and they would have to cast a new intake manifold for these particular engines.
Mudsport96:
From what I've read, it was because ford couldn't meet emissions with the other carbs on the engines that used the quadrajet.
unruhjonny:
wasn't it only one year of 429 Cobra-Jet engines?
.. or something along those lines.
Cliff Ruggles:
Ford used them on the 429 CJ engines, correct. They are very special units, having some very nice features.
I would imagine the intakes for them are excellent as well. Mopar went to Thermoquad spread bore intakes in the early 1970's for the same reason, to get thru ever tightening emission standards and made some very nice intakes for their engines as well......Cliff

i run quadrajets on all my fords excellent fuel milage and good power .just bought an 86 f250 2wd xlt lariat 460 pulled the timing chain and it was set up 8 degrees retarded pulled the holley off and intake and installed an edelbrock 7166 so that i could bolt the q jet on without a spacer . not quite finished . I'm expecting some very good milage and power.fwiw ps built a very nice fuel line to feed the quad made it out of 3/8 brake line that way there is no hose going to carb.i wish i knew how to post pictures.
