Edelbrock makes the Victor Tunnel Ram, with injector bungs, with open top plate.
Intake Manifolds - Chevy - Big-Block - Victor Series - Edelbrock, LLC.
Theres also the Pro-Flo XT intake, which I think is bad ass. Not really a traditional tunnel ram setup , but really cool imo. I think it be a nice top end for a EFI-540-565 build, rather than some lamo single plane with a throttle body on top. Seen enough of those already

Some good info here. They had a 540ci, 8.8:1 compression, 271/280 .742/.715 lift cam , Dart 355 cnc heads.
Weiand Team G single plane with dominator = 770HP/663 TQ
Weiand Tunnel Ram, twin 950 carbs = 777HP/681 TQ
Dart Tunnel Ram Twin Dominators= 806HP/694 TQ
Dart Tunnel Ram ported by Wilson = 833HP/712 TQ
The Wilson ported combo is up a solid 50hp at 6000ish rpm, and 30-40ftlbs thruout the midrange. Doesnt look like it gives up anything anywhere to the single plane setup.

I was looking into the option of going to a tunnel ram setup with EFI on my big inch NA motors. I don't think you could realisticly have a better induction setup. The long intake runners of the tunnel ram with fuel curve adjustability of the EFI. I wanted to go to a little different cam profile to try to take advantage of the induction setup then see what the dyno had to say about my idea but found a set of 10-71's I just couldn't pass up. Going with carbs on top for now but eventually I would like to go to an EFI setup on the blowers too. We'll see how things go.
