Typical Mopar stroker motor. Putting a 440 crankshaft in a 400 block and topping it with Edelbrock heads created 550hp on the engine dyno. Rear wheel torque is over 400 ft.-lbs. from 2,500 rpm to 6,000 rpm, yet it idles at 850 rpm with 14 inches of vacuum. Our camshaft is an ancient Mopar Performance 0.528 solid lifter grind. I suppose we should step up to something modern one of these days!
