Performance Online, or POL for short, has been in the business of building and restoring custom and classic cars for over 30 years, and selling high quality performance products. Renowned for their love old GM vehicles, along with Fords, Mercurys and Mopars, the POL crew specializes in helping customers restore their classic cars and trucks.
Located in Corona, California, POL is no stranger to building vehicles that showcase their products, including a ’66 Nova, ’68 Chevelle and a ’63 Impala, just to name a few. The company’s Western Chassis subsidiary has expertise developing suspension and brake parts through years of drag racing, manufacturing and working with CAD software. POL designs products for maximum strength and durability while keeping them affordable. What makes Performance Online different is their experience and reputation among suspension specialists.
Deciding how to build this ’67 Chevy C10 shortbed, POL wanted a street truck that would showcase all of the parts available from their website and catalog and demonstrate how easy the parts are to install. Using the company’s bolt-on ’63-’72 Chevy truck drop crossmember, designed to increase ground clearance on trucks with a 4-inch drop or more, the trailing arm mounts have anti-squat provisions up to 4 degrees with five different trailing arm settings. This improves drive off of corners for better performance, and it allows for harder launches and quicker 0-to-60 foot times. Matching ’60-’72 Chevy truck tubular trailing arms made from 2×3-inch rectangular steel with 0.188-inch wall thickness increased ground clearance and added strength to the rear suspension. The tubular trailing arms’ unique taper maximizes strength while minimizing weight.
The factory 12-bolt rearend with a posi, 3.73 gears and a POL sway bar is suspended by Western Chassis shocks and springs. POL drilled and slotted disc brakes are used all around. In front, a POL 1 1/8-inch sway bar, Aldan coilovers with POL tubular control arms and Western Chassis 2.5-inch drop spindles, and a POL power steering gearbox were added. American Racing Torq Thrust SLs, 18×8 inches in front and 20×10 inches in back, are fitted with Nitto Invo 225/40R18 and 275/40/R20 respectively.
Calling on Custom Built Motors (CBM) in nearby Colton, California, a built 5.7-liter LS1 with 10.5:1 compression was acquired. To the base package, Edelbrock ProFlo 4 fuel injection was added, along with a Comp Cam (.566 intake/.569 exhaust, and 271/279 duration) and Doug Thorley headers, producing 420hp to the rear wheels. Connected to the 4L-60 automatic from Chino Hills Transmission with an aluminum trans cooler and a 2,200 rpm stall speed converter is an IE Driveline aluminum one-piece driveshaft. A Champion Cooling LS radiator keeps the LS engine cool even in rush hour traffic.
To accommodate bigger rear tires and wheels, rear wheel tubs widened 3 inches were incorporated in the pickup bed. Despite the frame notch and lowered stance, the depth of the bed remained stock to retain its utility, as opposed to show trucks with body drops and shallow beds. Doug Starbuck of Starside Designs was tabbed to straighten out the body, before applying Harley Matte Black and Gloss Graphite Gray Metallic paint. Selecting a design voted on by POL customers and online, the POL graphic makes the C10 easily identified. OE painted bumpers and Brothers Truck one-piece side windows complete the exterior.
Inside, the TMI Products classic sport seats and dashpad were done in red and charcoal gray, making the POL truck a standout. Vintage Air A/C, Dakota Digital gauges, a POL billet steering wheel and American Autowire wiring finished off the 11-month build. Street worthy and a joy to drive, the only drawback, says POL marketing manager Larry Ashley, is the tendency for onlookers to get a little too close in their attempts to view the small-windowed pickup while on the highway. A tough job, but somebody’s got to do it!
