FINALLY, A JON MOSS SPECIAL EDITION
Over the years, Jon Moss has been one of the few staunch supporters of the Chevy Bow Tie image, even when there wasn’t much to get excited about. Here’s a guy who took it upon himself to argue the fact that a company such as Chevrolet, which built its considerable reputation on performance and racing, continues its domination within this high-profile segment.
Hydro-Boost Brakes
Nothing is more terrifying than cruising down the street to the fairgrounds when some idiot pulls out in front of you and you have to jump on the binders. Making a panic stop can be difficult when you are trying to stop 800 throbbing horsepower with a set of 9-inch rotors and single-piston calipers. You might even wonder if it will stop as you mash the brake pedal. When it comes to street rods with big motors, one braking concern is vacuum pressure. Is there enough? Many high-performance camshafts add power to the motor but produce low vacuum levels. This is something to consider when selecting your engine components. Of course, if the motor fails, you will have no vacuum, so stopping will be a real problem.

Camaros are nothing new for Steve Felthousen. His father is an avid car collector and counts a ’69 Pace Car among his collection. In high school, Felthousen drove a ’73 Z28, and later he built a Pro Street ’69. Just to show how diverse his interests are, he also drove a ’69 Chevelle SS 396. But he soon began looking for another Camaro, and he knew he wanted a first-generation model.
