Twin Engine: 1954 GMC Semi Tractor

This has to be the strangest thing for sale on eBay right now, aside from Chia Pets that look like a human head, those things freak me the heck out.  Anyway, this next feature isn't freaky, but it has two huge inline-6 engines mounted up front.  Find this 1954 GMC Semi Tractor here on eBay bidding for $6,500 reserve-not-met with a few hours to go, located in Spokane, WA.


When you think twin-engine cars, you almost immediately jump to cars that have one powering the front wheels and another in the back, or perhaps a setup with two engines attached end-to-end, but today we've got the first twin side-by-side engine setup I've ever seen...apart from the quad Harley Davidson Jeep, but those were little V-twin engines...this is different.


A peek under the hood reveals two GMC 302 cubic inch inline-6 gasoline engines mounted between the widened frame rails. Each inline-6 has its own 4-speed dual range automatic transmission with driveshaft attached to one of two of the dually rear ends.  Now, why didn't I think of that?

  1. Yea.... and how exactly do you stop the thing with 2 brake pedals and 2 clutches?

    1. Automatic with a clutch? Interesting

  2. I was gonna say that you would not want to miss a shift when operating in two-engine mode, but I guess the two automatics kind of take care of that problem. The EBay description of the dual brake pedal set up raises some interesting possibilities, however....

    Anyway, the sellers seems to indicate that this beast actually worked, and worked fairly well, so my hat is off to the (now late) creator. I love crazy concepts like this.

  3. Did they just flip one of the differentials over so the offset was on the other side? Anyhow, great idea.

    1. That doesn't work. If you flip a differential over the wheels end up turning the opposite direction relative to the frame.

  4. This has me thinking. I would like to make a rat rod with the same twin engine, twin axle set up. I'd use a lighter set of rear-ends. One of the motors would be a Turbo RX-7 engine (0 Torque at lower RPMs, lots of HP at high RPMs). One of the motors would be a Cummins 4BT paint shaker (A ton of low-end torque, 3200 RPM redline). Oh, and I would make them share the same giant intercooler. Hehe.

    1. Just be sure to put the Cummins on the left side if you ever plan on spending time at an oval track. You should also consider using one single giant turbo shared between the two engines.

    2. I think if you could make such a beast function, it would be the hit of any show it entered. I, for one, would be drawn to such a contraption.
