A set back firewall may or may not be needed. I would be willing to guess a larger trans hump will be necessary.

are you sure you didnt get the measurements from a 4BT? a 6BT is longer than 34 inches, it is 40 plus the belts/serpentine. an AD GMC with a 248 was an inch and a half longer than a 235 and needed the rad moved inside the core support and a shorter water pump/fan to fit.
your youtube link shows a 6BT with the back two cylinders inside the firewall. the first link in the thread shows a 60-66 which has a couple inches more room than a TF.
here is the engine setback of a 6bt in a 55 TF

that truck used the dodge frame and running gear too.
