Horsepower Combos - Horsepower Rules

Steve Mundy's '72 Camaro was one of the most impressive cars we saw: big rear tires, a mammoth big-block, and a loud rumble at idle. Steve bought the ex-racecar online minus the engine. The guys at Ace Machine in Riverside, California, assembled the 564ci Rat, and Westech Performance dyno-tested the engine. When we first arrived to shoot Steve's Camaro he told us he just checked with his insurance company, and we could take the Camaro for a spin around town. One thing we especially liked was the Camaro's license frame that reads "9 seconds on pump gas."

With nearly 2 tons to move, Les Hays wanted to make certain that he would not have a power problem. So he assembled his own 588-inch big-block that converts pump gas into over 800 happy horses. Les's engine develops huge power by flowing lots of air through a set of Air Flow Research cylinder heads that flow 385 cfm measured at 0.600-inch lift. The bumpstick is a very big solid roller. We had a chance to hear the thunder of this motor and can attest that it is awesome.
