I forgot to mention the reason that I was looking at using a carb base was due to the limited throttle body size on the manifold.

Todays long runner intake manifolds lead to the old problem of transport delay.  The fuel is metered in at the mixer body, and any change in mixture will result in a temporary lean condition until the mixture catches up.  This can lead to a spectacular backfire through the intake.  On engines with a composite manifold, it can be ruinous.  With your jeep, its aluminum manifold should be ok, with the carb mounted relatively close.  The problem is not as severe with open loop, when using closed loop and the system you describe, there is a significant delay in mixture "catch-up".

From what I detect from your mail, it will be a blow through unit.

I have built a few motors using what you are describing. mainly SBC v8's. I got the best dyno results from open plenum single plane mild racing manifolds, like weiand. usually advertised to make power from 1500-6000.. I always got better results when installing a plenum divider, especially before the turbo made boost.

Hey guys, how about adding some information in your bio area so we can see a little more of who you are?
