    intake ideas for a 383sbc

    hi all, i want to change the intake set-up on my engine, currently has a tunnel ram/twin holley & i want to go single carb so i can take the scoop of the bonnet
    & replate the hole.
    what will work,whilst improving economy & low end grunt?

    a dual plane manifold will help...not a racey single plane job..

    650 vac sec holley...or edelbrock carb....

    Edelbrock RPM Airgap----Edelbrock 750 (1407) excellent setup for street / strip.

    That's my opinion of course

    ta guys,
    i'm getting the picture now,the trouble is that i have no intention of taking her up the strip, so what i really want is to use the low end power & not be revving the tits out of the motor.

    If you don't plan any strip visits I would use one of the manifolds aimed at street performance. The Edelbrock Performer is a good choice, but basically small runners to keep the velocity of the mixture up.
    Also a smaller carb like a 600 or 650 Holley will give better throttle response than a 750[ that means better off idle and mid range where we do our driving in the 'real world']
    A good 383 is a torque engine and with a sensible cam will be fun without being too thirsty.
    I run a 350 sbc with a mild hydraulic comp cams cam, a Street Dominator manifold and Muncie box and am satisfied with the performance, plus I can afford to drive it.
