PACKED WITH POTENTIAL
The Power Programmer is designed so that once the parameters are established and loaded, the unit is pulled and the program remains in the onboard computer until you elect to remove it. The HyperPAC is different; this unit stays in place. In addition to the three stages of performance tuning—the HyperPAC has all of the performance programming benefits of the Power Programmer—it also has diagnostics; an engine monitor with a complete gauge display; a dynamometer, which includes such items such as a horsepower graph; and our favorite, a dragstrip program. This program actually monitors real-time engine operating conditions, has a Christmas tree start, displays a timeslip and will provide you with “magazine-type road test” acceleration times in 10-mile increments. It will record and display important engine operating conditions throughout the run and will display drive wheel horsepower versus vehicle speed after each run—in both table and graph formats.

HEMI WITH AN ACCENT
We know little about European drag racing, other than our sources tell us it is hotly contested and very popular. Frenchman Herve Caen is a drag racer, and at age 35, is the owner of not one but two silver ’68 ‘Cudas. One is a nitrous-equipped 440 Wedge built by
BAD BOWTIE
Some guys love their Chevys so much that they’ll go out of their way to flush out and record every bit of their cars’ histories. Such is the case with Gene Lavine of Excelsior Springs, Missouri. Lavine is 65 going on 35. A car guy since he was 16, he

Most of our truck-building buddies can date and identify any truck you can come up with from any distance, even from deep in a grove of trees and clear across a fairground show-’n’-shine. That’s what truck guys do: They enjoy identifying a rusted old fender at a swap meet…
