Has anyone tried to build a flat 8 with two type 4 motors?

Theoretical questions.
Assumptions
2 motors each producing 100 HP and 100 Lb/ft of Torque

The motors are end to end, front to rear.
The cranks are fastened together either bolted or welded.

1) Would you get 200hp and 200 lb/ft or torque? or is there some multiplier...seems like you would produce more torque..

2) could it be done with a single ignition system available for sale off the shelf.

3) could you do it without two distributors? crank fired ignition system..I am thinking that there could be a wheel placed in between the motors to give you something to time from.

4) I am assuming either a nice FI system, or four carbs.

Has anyone done this?
I would like to see some articles or web pages if this has been done in the aircooled world...

Thanx in advance
