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?
