Mild Thunder - how do I get my hands on one of these Tr's from Wilson and can they be modified for sequential port EFI?
Do I just call them and give them my engine spec's?

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 :faint2:

Would be interesting to see that back to back vs MPI and merc racing efi manifolds. Send one to articfriends?

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.

160 additional HP from only an induction system change is impressive. Period.

Supercharge it and be done!

Guess I should've waited until I had my coffee.

Add in some Elijah Craig or Makers to that coffee:coolcowboy:

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.
