@Mike: I for one, don't know anyone that has one of these V6's on (Holley) EFI, except for the Chevy TBI system. I'd be very interested though if you decide to try!
But I believe that port injection is superior to these TBI units though.

I have flow tested the intake manifold and found with the stock two barrel carburetor the flow is about equal. With the Holley two barrel the center runner flow is very low. This is why the magnum intake has no divider between runner 1-3 and 4-6. If you look at the top of the manifold you will see the center runner makes a 90° turn, air don't like to make sharp turn so it restrict the air flow.
In my opinion, port injection is superior but with these engines a TBI would be better base on the intake limitation.
