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.

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).

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!
