One of the main reasons people buy Vettes is for the V8 engines they have under the hood. That sweet torque curve and deep rumble are signature attributes that make the Vette great.
That’s why this 1968 C3 Corvette with the Cummins diesel straight-six is more than just the little bit out of the ordinary.
This red-orange Corvette drag car started out life as the standard 1968 coupe before it was badly rear-ended and put off the road.
Ryan Lusk, the vehicle’s owner, decided that instead of rebuilding it to factory spec, he would make a drag car out of it. Out came the stock engine and in went the 396 cubic-inch V8, along with the drag-ready four-link rear suspension.
Lusk raced the Vette with its V8 until, according to Engine Swap Depot, someone challenged him to go in the different direction.
Instead of the run-of-the-mill V8, the C3 now carries the 5.9-liter Cummins 6BT inline-six cylinder turbodiesel like you would find in a mid-2000s Dodge Ram 2500 pickup.
It’s the strange combo for sure, but that doesn’t mean it’s slow. Power numbers aren’t noted, and in this video, Lusk is able to run an 11.88-second 1/4-mile at 129 mph. Not bad for the car missing a couple of cylinders.
Watch for yourself as the’68 Corvette rolls some serious coal down the strip.
