Well that seems to be what obscure car builder *[Devon West]()* thought when he stuffed a Chrysler V8 into the trunk of an [MGB Roadster]() to create one of the craziest, most dangerous, and yet most incredible builds I've ever seen. The 1979 MGB originally used a 1.8-liter naturally aspirated four-cylinder engine and a four-speed manual transmission, to drive the rear wheels. It also weighed less than 2,500 pounds, making it a featherweight by today's standards. However, West was having none of that. Instead he decided to rip out its tiny four-pot (which probably didn't run anyway) and stick in a 318-cubic-inch Chrysler V8 from a '66 Dodge Charger. Except that monster engine wouldn't fit in the MGB's tiny engine bay. So he stuck it in the trunk. ![]() ![]() ![]() However, to make the Chrysler V8 power the rear wheels, without modifying a rear transaxle to fit, West sent the power forward, through a Chrysler A-727 three-speed automatic transmission, to a Humvee NGP 242 transfer case in the engine bay, which seems to be held in place via chain. That transfer case then sent power rearward, to the MG's rear axle to power the rear wheels but, for the rear end to fit it all and manage the weight of a V8, it needed a modified Jeep CJ5 rear suspension. So the back end is actually lifted, sitting on steel wheels and General Grabber AT all-terrain tires. It's flat-out bonkers. From the driver's seat, you can actually touch the driveshaft that runs *through the cabin.* You actually have to reach over it to grab the handbrake. You'd better not drive this car with long hair or it might get caught in the U-joint, giving you an impromptu buzz-cut. Thankfully, West didn't need to install a wind-deflector for the cabin, as the V8's radiator doubles as one. If you need to stop quickly, which you very well might due to having a rear-mounted V8 in a sub-2,500-pound convertible, you'll have to rely on Dodge Neon front brakes. Yikes. ![]() ![]() I won't lie to you, I love this car. Don't get me wrong--it's insane. But the ingenuity behind it is impressive and there's something really fun about the "I don't care how it works, as long as it works" mentality behind it. I wouldn't drive it, because I'd likely need a tetanus shot afterwards, but I love the fact that it exists. Now I wanna watch [Mad Max](). ## Author Nico is a writer and reviewer from New Jersey who probably thinks he’s a lot funnier than he actually is. His love of cars began when he was just a kid playing Gran Turismo 3, grinding out enough race wins with a Mazda Miata to save up for an in-game RUF 911. That passion for small, lightweight sports cars drove his desire to learn more about the industry, get his hands on as many cars as he could, and bring those experiences to life on the page. He cut his teeth writing about BMWs, Volkswagens, and Audis, mostly, and has owned far too many of each. He’s on his fourth 3 Series sedan, but all of his old, cheap German cars have forced him to learn more about car maintenance than his mechanical capability can handle. Too many late nights have been spent scrambling to get a car running by morning so he could get to work. For some reason, he never seems to learn that old Bimmers probably aren’t the best daily drivers. But he loves more than just old German cars. He’ll gladly drive and discuss anything with four (or even three) wheels. Cars aren’t his only passions, though. Nico is also a big nerd and loves movies, video games, comic books, and cares far too much about the New York Giants. So don’t be surprised if you see football references or dumb, obscure movie quotes in any of his car reviews. ### Author social links [Instagram]() [LinkedIn]()
