This 1966 Pontiac Tempest is no longer powered by a V8 but a 12v Cummins 6BT diesel inline-ix. The engine and turbo combo produced 270 horsepower and 650 lb-ft of torque to the rear wheels on the dyno. The owner has a list of upgrades for the winter including improving the suspension, brakes, and routing the exhaust somewhere else besides onto the windshield.

Appears to me he needs a tune-up. I am not a diesel expert, nor do I play one on the TV/radio but, my understanding is rolling coal is not indicative of a finely tuned machine..
