techibspector1 here, I 100% agree with you. Any self-respecting 350 Chevy with L31 heads that will be streetable needs a 750 carb mounted on a long runner, dual plane, CLOSED intake manifold. DO NOT USE AN AIR GAP INTAKE ON ANYTHING OTHER THAN A 100% DRAG CAR,where the throttle is NOT modulated. By that I mean that there are basically two settings with a drag motor, idle and wide open. Street motors require modulation of throttle position as well as heat in the manifold to help atomize the air/fuel slug going into the motor. Personally, I think Edelbrock should be ashamed of themselves, suggesting that the hot tip for a street motor is the open plenum Air Gap. An Air Gap used on the street will work great in hot weather, but when the weather turns a little chilly, expect the motor to buck and snort because the fuel mixture is not homogenized.

I would choose a Cliff Ruggles 750 Quadrajet mounted on an Edelbrock 2516 or equivalent manifold made by another manufacturer because the price on this manifold is beyond ridiculous. I guess it's the "Marine" description that drives the price up. The description I would look for would include 1. (1500-6500RPM operating range), 2. (Vortec 1996-2002 heads), 3. (Spreadbore carb mount for the Quadrajet).

With this combination dialed in, you'd think you were driving a fuel injected motor.
