628HP LS7X BUILD

Some of the greatest feelings in life come with a rise in rpm, a dropped clutch and tests of traction stretching the boundaries of our physiology. These are the emotions many of us cherish, and while many factors can evoke such emotions, the single most influential force behind these kinetic kicks is torque (which is then equated into horsepower).

TURNED-ON, TUNED-IN ECONOLINE

In an unmarked garage in north central Oklahoma (parked next to an original ’70 Boss 429) sat the Econoline. After moving the dead varmint skeletons and wiping off many years of dust, Kirk’s rolling time capsule was ready to see daylight again. Since the 406 Ford FE big block was no longer “politically correct,” a modern powerplant was decided upon.

CAMARO MAN

If you ask car enthusiasts to identify their favorite ’60s Chevy, most will say a Camaro. If you want a more specific answer, you probably will get mixed responses between the ’67-’68 models and the ’69. Troy Leiphart is one of those enthusiasts who like the early models, because they are smoother looking than the ’69 and look meaner when done right. That love affair with ’68 Camaros started when he was a kid. His older brother Ernie owned a maroon ’68, and Leiphart thought it was the coolest car around. After awhile, money got tight for Ernie, so Leiphart purchased the car from his brother. Leiphart drove the cool Camaro with much pride, fixed it up and spent time at the drag races, where the car did well. Eventually the engine blew and he couldn’t afford to fix it, so he sold the car back to his brother.

SUPERCHARGING FOR BIG POWER

Building an engine that produces more horsepower than its stock configuration can be done in many ways. However, supercharging has proven to be one of the best ways to make the most horsepower over stock. Superchargers are air pumps that force a “super” charge of air into an engine, which in turn allows the engine to make more power. A Roots supercharger or blower is a sealed case with two rotors inside. It is driven through the crankshaft by belts and pulleys, causing the spinning rotors to force compressed air into an engine.
