    Just got my first 84 Blazer... Hit the dirt a few time this week and she is boggin too much at not the worst of angles... right now she has a edelbrock 650 and I have a new Carter AFB 770(gift from friend)... I have heard the Quadrajet is the best, but untill i get some extra cash, I gotta deal... My question is what carb of the two I have would be the best... would different jetting help and if so what would it be? Any ideas would help... thanks

    Hands down the Q-jet is the best carb for off road.
    I tried an Edelbrock and wound up sticking it on one of my 2 wheel drives.
    I tried the kit and it was a waste of money IMOHO.
    HP books has a book out for the Q-jet that has a lot of good info in it.
    Doug Roe has the goods on this carb. and it is worth the money .
    I don't care what anyone says ... the Q-jet is the best carb on or off the road.
    See ya

    The edelbrock and carter are the same style carbs. So you will gain nothing by switching. Sell them both and buy a q-jet.

    I also have the Edelbrock 600 with off road needle and seat and it works great for me too. Just make sure you set your float levels correctly when you install them.

    Nobody I know is happy with the Eddlesnot off road. Get a Quad from about a 79-81 (before that electric mix control. You can covert them to electric choke no problem and the will just about run upside down. If your ordering it from Jegs the one you want is the 350-1904. Bolt it on and go. only need to adjust the choke. The 350-1903 is the same carb without electric choke but your already wired for electric so it would be the way to go.

    I am running the Edelbrock Q-Jet 1901 w/devorced choke (old style). This carb has been GREAT!! I have been running it for over 5yrs and it still doesn't skip a beat or cut out on the hills and bummpy roads. I would recoment this carb to anyone and in my mind the only thing that could be better for off roading is FInjection.....

    Man I was ripping my hair out with my 75 with the 1901. Kept dying on my nose up. Rebuilt it twice...No luck. Then the fuel pump started leaking. Turns out the whole problem was the pump. It had a leak and was sucking air. The fuel got airated and when nose up it was sucking bubbles. LOL Not a single hickup since then.

    Yes, Q-jet, quad, whatever, same thing.

    I've got a 500 CFM Edelbrock but I'm swapping for a Q-jet when I get time to learn to rebuild and tweak one.

    I have a edelbrock performer 640cfm, I was hoping I could stay with that since I pretty much just bought it, but the damn thing makes the engine stall out if you get at any kind of more than average angle. Can its staill angle be improved at all? or will I be saving myself a lot of trouble by finding a q-jet and using that instead?
