Engine
This engine, and others like it, has opened up a brand-new chapter in the ever-evolving, wild world of Chevrolet power. By design it has a bore and stroke of 4.60 inches by 4.25 inches and Big Chief II heads, which are about 2 inches taller, that feature oval-shaped intake ports. This, they say, is for maximum cylinder filling. Years ago, creative racers would angle-mill heads to arrive at the desired combustion chamber size and to improve the valve angle in combination with the incoming intake flow. These heads are nicknamed “11-degree” heads, as they have been designed with a built-in 11-degree angle right out of the box. There’s no angle milling needed here. A special valvetrain is necessary, along with longer stem valves. Quarter Mile Performance feels that these heads are worth 200 additional horsepower over the very best “shorter” heads.

It often takes a serious challenge to test a person’s capabilities. After years of driving a string of performance cars, Terry Short wanted something different sitting in his North Tonawanda, New York, garage. So, he set out and found this ’55 Chevy big-window pickup in an apple orchard. He just knew he had met his challenge.
Terry Short’s ’55 Chevy pickup has a just-right rake, a monochromatic finish on a super-smooth body and a potent big-block Chevy. All these elements combine to make this Hot Rod Red truck a perfect cruising machine. Short’s goal was to build a truck that if you couldn’t see it, then you could certainly hear it coming. Though the roof went unchopped, the remainder of the body was extensively reworked and is devoid of chrome accessories.
