    Weber TBI + What intake manifold?

    As the title says, IM running a 360 in my CJ. I use it off-road about 10 times a year mainly in mud and on trails.

    So When I do the Weber TBI what intake manifold should I get?
    MPG is a slight factor as I get about 9 now.
    I would like to get a bit more out af a gallon.

    What should I get for the best MPG and not sacrafice to much off-road?

    I run an Edelbrock Performer with my Howell TBI. It was the only manifold that would fit the GM TBI adapter. Don't expect a big gain in fuel mileage, I only picked up about 1 MPG with fuel injection. My 360 powered CJ7 averages about 11 mpg on the street, much less on the trail. That's running a mild cam, stock bottom end, 291-C heads that have been polished/ported/gasket matched, stock exhaust manifolds, 3" single exhaust w/cat (smog requirements).

    Remember that a Jeep is about as aerodynamic as a brick, and gets about the same gas mileage.
