We’ll call Cho’s efforts a modern retro. Much like old heavy-metal bands, classic metal has a timeless appeal, but there’s more—lurking beneath the classic sheetmetal is newfound power that will appeal to both schools of thought; purists will appreciate the clean lines and fastidious restoration, while performance mongers will be delighted to know that the original small block was scrapped in favor of a big block.
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.

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.
Bonneville is that final frontier, a place where a man or a woman with a better idea isn’t punished with a bunch of extra weight or politically ruled out of racing. It’s a place where a person with a better idea gets in the record book until someone with a better idea takes it away. It’s that simple, and it’s speed racing at its purest.
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.
