The problem would be to balance the two engines. Which is why you
typically see either 1 shaft per engine or one generator per engine and
a electric motor driving the screw.



I looked at a 30's Packard that did this, It was a mechanical monster.
Both engines were coupled together to a single drive line. The power
plant was called a "Twin Six" is my memory is right. A guy was selling
it and told me it took him about 10-15 minutes to get the engines in
proper sync after they were shutoff. This was needed to make sure the
strain on the "box" (Can't recall when he called it") where the two
engines were coupled to a single drive line would break.

The trick here was not to just get them idling at the same rpm. But when
one would tap the gas pedal the rpm's had to "bounce" the same. It had
adjustable choke gas and magneto slide adjusters to help one get it in sync.

This was a car that was designed to be driven by a professional
