    I was told that predator carbs don't have an idle circuit. This has to be added with other parts you can get from predator. That's what I was told.

    I'm not sure who makes the carb unless there an independent company. I think they make a street version with choke and idol circuit. P.A.W. sells them I guess I should call and ask the techs what they think. First hand experience is always the best though. /forums/images/graemlins/rotfl.gif

    OK just talked with P.A.W. and they said they are designed for 4x4's. They make a street version with idle circuit and a rear mount kit for 4x4 use, the tech said they WILL NOT load up or flood on any angle, that's why BIG FOOT ran them. Sounds pretty cool but the cost is 459.95 with a 22.95 "BellCrank kit" . Sure would like to hear from a fellow K 5'er that has experience with one. /forums/images/graemlins/thumb.gif

    I ran a Predator on a 454 for almost 5 years and I was very happy with it. I NEVER had it stumble while wheeling, in fact I used to joke that it would probably run upside down. You can expect, however, almost no gas mileage from it. I went from a Holley 750 getting around 12 mpg to the Predator with no other changes and my mileage dropped to around 4 mpg.

    I used the "race" version on my truck without the idle circuit and it was fine. I have worked on one that had the idle circuit and I didn't notice any tuning or running characteristics different from the "race" version.

    In the end I took it off because my motor simply outgrew the carb. Being a variable venturi design the Predator tends to be a little slow to feed the motor. It's cfm is determined by vaccum demand, therefore the motor has to need the fuel for it to give the fuel. After a cam change, I found it to be sluggish when compared to a larger Holley mechanical secondary carb.

    It definitely had it's gives and takes but I don't regret using it at all.

    WOW, thanx for the info thats just what I was hoping for a real experience. I am disappointed to hear that the M.P.G. is so lame. I am still considering it but I need another daily driver first. THX /forums/images/graemlins/thumb.gif
