The only thing more fun than sitting in a chair at a car show is sitting in a chair with a gas pedal in front of it, or at least that's how Trent Summers and his son Jason Brady of Huntingburg, Indiana, view the world. You see, Trent works for Goodguys, and is in charge of setting up the autocross track at every venue on the Goodguys' nationwide calendar, and Jason works for RideTech in the marketing department.
When we reached Trent on the phone he said he was in Ft. Worth, Texas, and had just finished building the track for the 4th Spring Lone Star Nationals. Our first question about the truck was the origin of his competition C10's wheels. Trent explained that he couldn't find the wheel configuration he was after to suit an 18-inch tire, so they had to make their own wheels. Trent's wheels are based on Wilwood Wide 5 hubs grafted to 12-inch Wilwood rotors adapted to mate with aluminum hoops (rims) manufactured by Spin Tech. For sticky tires, Trent looked to Falken for a set of four Azenis 615K all matched to 315/30/18 specifications.
Before Trent and Jason started the project they were told a stock C10 chassis couldn't be made to work, so the challenge was to highly modify the stock frame to work. Up front the IFS is a No Limit Wide Ride steered by an Appleton rack-and-pinion with a Schroder steering wheel topping a Woodward steering column. If none of these brands sound like the usual players for a 1967-1972 C10 that's because they're all components strictly intended for racing. At the rear, the truck continues to sport a trailing arm arrangement, but a No Limit unit has been put in place. The rear brakes are 12-inch Wilwood discs and a Tilton master cylinder handles pushing the pucks.
Under the hood is where things really get wild. A 408-inch LS series blueprinted and balanced engine is equipped with all the go-fast goodies. Hilton Motorsports in Waterloo, Ontario, Canada, handled all of the machine work, and then assembled the engine. When it was all said and done, the LS pumped out 550 horsepower at 5,800 rpm. The transmission is a Bowler beefed 4L80 with a Winters quick-change hosting an infinity of rearend ratios.
The basis of the autocrosser C10 started when Summers and sons put the word out they were looking for a 1967-1972 Chevy pickup to build. It wasn't long before a friend put them onto a 1970 that was half-rusted to death for $400 with a good title that had been left in a sand pile. As with all street vehicles intended to convert into a race car, the first thing was to blow the floor out of the cab and fabricate a new floor pan. There was about two-thirds of the cab that could be saved. The bed was totally rusted junk and was replaced lock, stock, and barrel with a complete new bed from LMC Truck. LMC was also the source for the 1969 model grille. The super glossy DuPont black paint was shot by Scott Mehringer of Jasper, Indiana, and then Jerry Carr pinstriped and painted the red graphics on the body. Cale Kern custom fabricated bed lid.
Inside the cab, as one would expect, the C10's interior is strictly business. A stock GM dash is home to a passel of Auto Meter Ultralight Series gauges. A B&M air shifter takes care of controlling the Bowler 4L80 transmission and Butler-built 15-degree layback buckets comprise the seating arrangements.
Believe it or not the Summers & Sons autocrosser C10 (thanks to that good title we talked about) is street legal. Trent admitted that in its present configuration it's hard to drive in town and not real popular with the local police.
