Gary at Magnum Superchargers did the machining assembled the short-block, and Rob did assembly on the 468ci Chevy big-block with Edelbrock aluminum heads that now powers the C10. Mass-Flo EFI on an Edelbrock manifold keeps the fuel and air coming. On the exhaust side, Hedman headers and MagnaFlow pipes and mufflers handle spent gases and sound a nice note. S&W Transmission put together a Turbo 400 and converter, connected to the rearend by a Drivelines driveshaft. The GM 12-bolt features a 3.73:1 gear ratio and an Eaton Detroit Locker differential.
Inside the cab, the stock tach-equipped dash remains, but the rest is modified, from the LeCarra steering wheel on a GM tilt column to all that black upholstery from Katzkin Leather. Cobra Daytona racing seats, Simpson harnesses, and a chrome-moly harness bar built by Emmanual Rojas were added after Rob caught the autocross bug. Classic Auto Air A/C keeps everything cool, and an Eclipse head unit and Kicker audio components, installed by Geoff Curtis, insure that the big-block doesn’t drown out the soundtrack.
Rob says he had never seen an autocross race before April 2010, when he was displaying his truck at the Goodguys Del Mar Nationals. On Sunday, after watching the action for two days, he decided to put the C10 through the cones just for fun and was hooked. He got busy setting up his suspension to make the stock-framed pickup more competitive in the sport of surefooted g-Machines. The most successful component, hands down, he said, is the Hotchkis suspension setup. He runs a Hotchis Sport Suspension TVS kit, with front and rear anti-roll bars, front and rear springs, front centerlink, rear Panhard bar, and steering componentry. The AFCO double-adjustable racing shocks provided another big improvement in handling. He also switched to lightweight MHT Mach X forged three-piece wheels (19x12 and 19x10) wrapped in huge Nitto meats measuring 335/30R19 and 275/35R19. The 14-inch Baer brakes all around have been on for 3,500 miles and still grab like a pit bull jaw.
The OUSCI was a great shakedown for the suspenion. Now Rob and support crew/fiancé Jessica Goud (the other key to his success) can’t wait for the next chance to run the C10 through the cones. CCT
