Thread: Single plane intake manifold

  1. #1
    ZRCTION
    496 bbc, 9.5:1 comp, oval port heads have'nt decided on a cam yet but it will be a big nasty flat tappet solid lifter from Clay Smith. I was curious what single plane intake works best? Single 4 barrel Holley 850cfm. I see the Victor is used alot but what about the Team G? Any others?

    Dart.
    I wouldn't hesitate to use either of your choices, or the dart, except the issue of your oval port heads, and the availability of your manifold of choice to match them. I don't know if you could port match a rectangle intake to an oval port head.

    ? probably upwards of 7-7500rpm. Rock solid bottom end, still deciding on a cam. I just know I want to get rid of the air gap dual plane intake I have now.

    You'll will then need a single plane..

    Very hard to beat the Dart Oval Port Single Plane Intake. Especially if you are dropping it in as cast out of the box. Well worth the extra $100 over the other manufacturers intakes.
    I'd still use this in your application even if you where building a mild 5500 rpm motor.
    I hope your oval ports are atleast mildly ported by a Professional

    I have a Holley Strip Dominator (large oval port)for a BBC that I ran with my big oval port heads and 850DP if you are interested. PM me if you have any questions. .
