And that is the real advantage of modern day fuel injection. Unfortunately we do not have these available for BBC's.

Since we don;t have to worry about fuel getting into the runners and then into the combustion chambers with EFI, we can build longer straiter runners, attached to a pretty large plenum, and package it to fit under any hood. :)

Just imagine if someone made an intake like this for BBC's where you can bolt in a different set of runners :)

It just seems that a tunnel ram machined for injectors with a couple throttle bodies on top would be pretty trick.

You can get the Dart (and others) that way now if you want.

Motorcycles started to use variable length stacks on the injected bikes years ago to have the best of both worlds. Granted, small changes make give a lot of difference on a 400-500LB machine. (seems like I typed this before,,, maybe I should drink and type).

I think spraying the injector right at the back of the intake valve would probably help you slow idle down a giant cam though.

How does a tunnel ram compare to the Hilborn style stacks? I'm guessing they are roughly the same height, but with the tunnel ram having a plenum area that the stacks lack.

that will depend on who you talk to and where the injectors are placed. One thing that the kinsler hilborn won't do in rough water is load up. The it intake are little harder to evin out balance the air going in.

Stacks are probably best. The plenum is infinite. A tunnel ram could probably get close or match them if it’s optimized. Pro stockers run tunnel rams!

One thing pro stock was not allowed to do was place the injectors where they want. And they can't run ir intake. I did like fuel injection on pro stock and flat hood.
