    I don't think you are going to find many on here that say anything bad about the Q-jets. Stock ones last well over 130K, so one rebuild done right, should have fixed yours up for plenty of time.

    Q-jets don't have very many wear parts, and I just don't see the casting/hard parts wearing out in our lifetimes, unless it was mistreated.

    The worst that can happen to Q-Jets are the throttle shafts wear down a little , creating a vacuum leak. Good carb shop could press in brass bushings. Edelbrock and Jet both make good Q-Jets. I really do not reccomend running an Edelbrock or Carter AFB based carb off road. You really have to modify them to keep from stalling or flooding at extreme angles. Its my personal experience that a Q-jet will keep idling beautifully on hills that scare the @#!$ out of you !

    <font color="green"> I'd at least try to run the Edelbrock carb and the Performer manifold that you already have. For about $20 and an hour of work you should be able to get that carb to run real nice both on and off road. I run a Performer carb with the off-road mods and I love it. Great gas mileage and it works real well off road. I know it's not a popular choice on CK5, but it is a hell of a lot easier to tune that a Q-jet. </font color>
