Double Trouble; Twin engines

This is a pic of "Double Trouble"


While I can see some detail in the pics from that page, I have some questions.
How does one connect two engines to the driveline? How do you synchronize them?

I'm just curious. Any links for a HOWTO or discussion?

It's in the specs listed at the bottom of the linked page, a 90MM wide toothed Gilmer belt(like a big 6-71 blower belt) connects the two cranks to a central custom jackshaft that drives an ordinary Ford C-5 trans Drive is enclosed in a custom bellhousing fabbed by the owner, looks like made of aluminum plate to me .

Builder says the think of a large triangle for belt routing.

Fun to look at but I bet it isn't as fast as you might think.

Saw this driving on Counting Cars on the TV.

Really. That's a lot of weight over the front axle.

Anybody see any in-line V-8s?

I did find this: Twin Engine Coupling (How Do You Get Two V8's In-Line?) - Page 2 - THE H.A.M.B.

A friend of mine built a Gilmer belt drive reduction box out of aluminum plate onto the block flange of a 350 Chevy...To slow rpm to correct speed for a 5' Laminated Wood Airplane prop when he built has own swamp Airboat. Machined his own Gilmer pulleys for it also

We used inclosed gear & quad-row chain drive from engine crank to crank and electric Motor couplings to differential instead of universals because of the massive torque! And a variable speed drive and forget about your old car trannies !!
The thing that suprises me is the little single V belts on each blower ? And HOW DOES HE SEE PAST THE ENGINES TO DRIVE ON THE STREET???? I get a ticket because of my fuzzy dice and baby shoes on my mirror !!!!!!

Double trouble is a beautiful piece of engineering, but it not really a rod for the average guys street ride! I certainly like that GMC V12. Question is where can I get one. When I started building I was looking for something different, not the usual V8s you see so often. I prowled the wrecking yards in southern Ontario Canada and contacted yards in the North eastern US for one of GMC's BIG sixes, a 427 or 503 with no luck. had to settle for a 292 Chev. Looks and sounds good. Also looked for one of the V16 Cadillacs. One of the yards had one but it was well beyond restoration. I like unusual and Double Trouble is beautiful, no doubt.
