    I know there was a post a while back about this but I couldn't find it. So what are the pros and cons? Anybody actually used one?

    so far no one has posted real info on the new metering blocks.
    this is the only area that needed work on the Holley for climbing.
    the petersens review was a waste of paper, like most of their reviews.

    I wonder if the new blocks would work on a older carb body? And yes the vent looks trick but a piece of hose from front to back with a hole at the top always seam to do the trick for me.

    the vent was never really the problem.
    when climbing the fuel in the float bowl ends up higher then the main discharge nozzles and the fuel starts to gravity feed

    similar but not really the same.
    with the dragcar you are at WOT and the motor can pass the fuel easier, and a lot less is coming only the initial G forces.
    with a 4x4 you get as much fuel as the pump can feed through the restrictions the entire time it is nose up.

    I got my Truck Avenger for x-mas, I've been running it for about 6 months and will never go back to a q-jet. It inproved both my power and my gas milage, I don't do any hardcore rock climbing but have not had any problems with fuel flow, or bogging down - going up, down, and sideways, upsidedown may be a problem, but will kepp ya'all informed.

    even good on the real nose up stuff?
    my Holley kills the old Quadrabog everywhere but climbing.
    power driveability etc

    good to hear it is working for you

    I thought that there was a new Q-Jet out that they say is the next best thing to efi??? It was in one of the recent 4 wheeler mags.. they tested it in a jeep and laid it on the spair a few times and on its side and the motor never hesitated?!?!?!? I am only curious cuz I am gonna buy one of these carbs either the holly or q-junk.....

    The nose up is not a problem, nose down it tends to start to load up, but not enough to cause a stall.

    I have a Jet Q-Jet Stage 2 and it is like having fuel injection. My buddy has the new holley and he likes my q jet better than his. I have drove both trucks and they both run well, but the q jet has a crisper throttle response. Doesn't the holley have a lifetime warranty??????

    $398? That's all? I paid over $500 for the 1910 Edelbrock QJet! I love its offroad abilities, but it really sucks for acceleration over the old Holley 750cfm puddle-dumper I used to have! /forums/images/icons/tongue.gif
