    Q-Jet E4ME

    Post  Xtreme Thunder on Tue Oct 13, 2015 11:54 am

    I am currently going over my options for some engine rehab (short term) as the stock LG4 is seriously lacking power and showing its age. One option is to stay carbureted, however, I would like to keep all emissions, and as such, the Q-Jet E4ME (CCC). Does anyone know the flow of this carburetor, i.e. would this unit be able to be installed on say a 350/ 383, that produces probably more than double the power when comparing the stock LG4 305?

    I did some further digging on the other vehicles this carb came installed in. It appears, when properly adjusted, they can support higher horse power numbers on engines other than the 305. Many are have reported many successful installations on 350 and 383's when using nothing more than a mild cam.

    Too many options.

    Most quadrajets flow around 750cfm. I like quadrajets, ive never had a problem with them and ive rebuilt many of them even the ccc ones. But id only use them on mild builds ofcourse, no one would be running a quadrajet on a 700hp motor, wouldnt make it, but if you want a more along the lines a gas savings and mpg's keep that quadrajet, doesnt mean they dont perform, but they are much more street friendly. I like the fact that they have very small primaries which is excellent for low rpm torque, and then the huge secondaries, loved hearing when they opened up, was a unique sound.

    Thanks much! It is either something along these lines or a Gen IV small block, which I have done extensive research on and have identified all parts required.
