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.
