Horsepower Combos - Horsepower Rules

Scott Miller knows it takes a truck to haul, so to his factory 355 small-block he's added both a supercharger and a dose of nitrous. With the supercharger, better breathing cylinder heads, and a high-lift cam (minus the funny stuff) the combo has produced over 500 horses and 500 lb-ft on the dyno. To feed those extra horses, he improved the fuel system with parts from Holley. What's especially fun is that on the track the 4,000-pound pickup stops the clocks in the low-12-second zone.

This Nova may look like just another show car, but it packs some impressive power. Under the flaming flanks Chuck built a 406 small-block from a stock GM two-bolt main block and added AFR 210 cylinder heads, a hydraulic roller camshaft, a moderate amount of compression, and an adjustable NOS 150-horse kit. An MSD ignition system ignites the air/fuel charge. The package has been dragstrip-tested to power the X-body through the quarter-mile in the low-11-second range.
