    Has anybody here successfully installed their Q-jet in reverse? If so, how did it work and how did you rig the bracketry?

    Why would you want to do that ? Stall uphill instead of down ??

    There's a number of EB guys who have done exactly that. I don't know how it benefits, but there's those who claim that mounted backwards gives performance that is really close to EFI.

    B4 I did anything like that I'd be looking at extending the bowl vent as high up as the air cleaner will allow. After that I'd go floatless. After that I might think about turning it around, but at that point I'd just go TBI & be done with it.

    The idea of turning the carb around is so that you STOP stalling going up hilll...when fuel requirements are high and the jets are starving. I have already extended the vent fuel as far as I can and TBI is pretty much out for the time being (unless omeone wants to help me dial it in) as I suspect getting it to work with my 383 will cost more and take longer than making a "z bar" to install the carb backwards...


    Who are the "EB guys"?

    Aside from a real steep short downhill where my bumper touched ground , my quadrajet works great uphill . I call it Fool Injection .

    Uphills are my issue, not down...I can do fine going uphill as long as I don't mash the accelarator, but on real lose terrain where I need HP and speed, the carb starves, especially on hills that are a few hundred yards in length...

    I think the E.B. guys mounted the Q Jets backwards due to a linkage issue.

    the qjet has the primary jets in the front of the carb, when going up a steep uphill, the gas uncovers the jets causeing it to stall. turning the carb around will put the jets in the back that will almost always covered in fuel when going uphill. they will be uncovered when going downhill, but you usually don't need any throttle and the motor will still run.

    when i rebuilt my old qjet, i raised the float level and never had a problem going up or down. i did have choke issues and took it off in favor of a reman carb. this carb has the float level set alot lower. it stalls out going up hill, i have even stalled it going down hill and couldn't restart (stuck in sand). the float level will do alot.
