Has anyone converted a small block tunnel ram to run 6 pack carbs? I have seen some awesome manifolds for 440's but never a 340.

Looks like a no  BUT I don't see why it couldn't be done, If the T/R has a removable top you could just fab a top for the 3 carbs. I can't see them making more power than a 2 x 4 but they would look cool.

I imagine the only way you'd do it is by making a new top for an existing cast or sheet metal tunnel ram
It would be a cool project I am sure.

The advantage to using the Weiand ("say 'Why And'") as the base (instead of ordinary TR): longer runners to lower tuned RPM + extra inertia without the height problem. I make some comments on the Weiand on my site here: http://victorylibrary.com/mopar/weiand.htm

Anybody have any idea what it would cost to cast a few of those tops? Or maybe a forward facing EFI top?
In theory, there is no difference between theory and practice. In practice, there is.

Ten times what you would pay for it

I think you could have a fabricated aluminum top made for $500ish. I don't think a cast top would be economical.
