Internal combustion technology is downright insane these days, and that includes diesel powerplants. Four-figure torque numbers are relatively common now, but what happens when a 1970 Chevelle gets stuffed with a twin-turbo Duramax diesel engine to produce a whopping 1,100 pound-feet of torque? Well, let’s just say that certain components get a bit stressed, as seen in the following feature video.
Once again coming to us from the folks at AutotopiaLA, this video is just under 22 minutes long and includes both specs and a walkaround on this custom 1970 Chevelle, plus some antics on the street.
Let’s jump straight into what makes this 1970 Chevelle SS unique – the twin-turbo Duramax diesel engine. This specific powerplant is the 6.6L V8 LBZ, the same oil-burner found under the hood of the 2006 Chevy Silverado HD and GMC Sierra HD. Originally producing 360 horsepower and 650 pound-feet of torque from the factory, this polished eight-cylinder was heavily massaged by its previous owner, and is now throwing down with 650 horsepower and a world-turning 1,100 pound-feet of torque. Interestingly, it also gets as much as 33 miles to the gallon, or so the current owner claims. Sending all of that output to the rear is a G-Force GF-5R manual transmission, which was upgraded to handle the extra power and twist.
The current owner was originally thinking about flipping the car for a quick profit, but eventually grew fond of his diesel-powered Chevelle.
“I like it,” the owner states. “I was thinking about putting it on Bring A Trailer because it’s such a unique car, but I honestly like it.”
The car was built during a frame-off restoration and now runs coilover suspension and Wilwood disc brakes. Notably, the diesel powerplant adds some extra weight to the equation, tipping the scales with an extra 200 to 300 pounds over a standard Big Block-powered 1970 Chevelle.
It’s definitely a unique build, and worth checking out – especially if you’re interested in what might go wrong:
