This Rusty Old Chevy Truck Is Hiding A 650-HP Supercharged Duramax Engine

Trucks / Comments

And a ton of modifications.

Everyone knows that America loves V8 engines, even the diesel ones. And much time and effort is placed into mounting these engines in cars that they don't belong in. We love a good V8 swap, especially if it's something unique like a large-capacity diesel, and even more so if it's going into a classic truck. The Duramax diesel engine has been suffering from some supply and production issues of late, with trucks such as the Chevrolet Silverado 1500 feeling the consequences, but Banks, the exclusive worldwide distributor of the GM Duramax engine, has gotten its hands on a supercharged R866SC Duramax diesel engine and fitted it into this 1966 Chevy Truck. Lovingly called "LokJaw", the end result is quite amazing.

LokJaw will be used as a showpiece for Banks upcoming high-performance turnkey diesel engine program. From the outside, this old truck doesn't look like much. Other than the early 2000s big chrome wheels and a few stickers and pinstripes, this thing looks like a rust bucket, but there's a ton going on underneath that flaky exterior.

First off, Banks decided to keep this ¾-ton long bed truck an eight-lug machine, which now makes it one of the first air-bagged 8-lug chassis. Stopping power has also been increased thanks to a Wilwood's TX6R Big Brake truck kit with 15-inch rotors and six calipers in the front. Power is sent to mother earth via a set of Nitto Invo Street tires and NT555RII drag radials with one-off billet aluminum wheels. The interior features full leather upholstery, four Banks iDash DataMonster digital gauges, and a decent sound system too.

We saved the best for last: the engine. LokJaw's 6.6-liter Duramax diesel engine does not feature any turbochargers. Instead it gets air forced down its throat courtesy of a Whipple Gen 5 3.8L twin-screw supercharger and liquid-coupled intercooler. For even more performance, Banks added a notorious oxide injection system. Power, which is estimated to be between 600-650 horsepower, is sent to the rear wheels via strengthened Allison 1000 6-speed transmission built by ATS Diesel. The engine and transmission are controlled by a MoTeC M142 ECM, and Powertrain Control Solutions paddle shifters. Banks is currently working on turnkey solutions for both a twin-turbo, and a supercharged offering and plan to launch its new products in 2022. It is estimated that LokJaw's build cost comes to $350,000, and customers can expect to pay around $40,000 for one of these badass Duramax engines.
