VIDEO: Aldan American’s C10 Slays the Autocross


Timeless Muscle is a publication that showcases classic Americana through the muscle cars of the 1960s and the 1970. Or title focuses on not only capturing the essence of the muscle cars of yore, but to shed light on emerging trends. One of those, is the classic trucks of the era, like the ’67-72 C10s. Depending on what part of America you’re standing on, you may or may not have seen a C10 like this before.

Built by Aldan American to showcase their C10 truck coil-over product line, the build certainly lends credence to what’s happening in the automotive aftermarket at this time. Being on its maiden voyage at the 2017 Super Chevy Muscle Car Challenge, (sponsored by Falken Tires and Classic Industries), Aldan American’s Garrett Harmola tells us that it performed great!

The truck was thrown in the middle of a slalom, 100-yard dash and a road course fill with tight corners, a few bumps and a hard-braking runoff.

Under the hood, you’ll find a modified  450hp LS1 powerplant backed by the venerable T-56 gearbox from a ’99 Camaro. The rearend is a full float 12-bolt with a Posi-traction, a Watts link and 4.11 gears. Wilwood 14-inch front, and 12-inch rear brakes bring the track to a halt in a hurry, as well as 2-inch drop spindles in the front bringing the front nose to the ground, but it’s in the suspension that makes our mouth water the most.

The suspension breakdown is as follows:
  • Aldan American Striker Series, double adjustable coilovers, Part # AS-754 (14.0″)
  • Aldan American coil-springs, Part # 10-650BK2 (2.5″ ID x 10″ x 650 lb)
  • Scotts Hot Rods 67-72, C10 Bolt-In IFS
  • Aldan American Regulator Series, single adjustable coilovers, Part # AS-658RS (16.5″)
  • Aldan American coil-springs, Part # 12-300BK2 (2.5″ ID x 12″ x 300 lb)
  • Custom trailing arm with coil-over setup, c-notch
  • POL 60-72 C10 tubular trailing arms
  • POL 63-72 trailing arm crossmember

The Harmolas finished the truck off with a set of Intro Wheels, “Bullet” – 18×10 Front, 18×12″ Rear (Powdercoated Black), and the perfect shade of grey — which is actually a popular color choice these days. Garrett tells us that the tuck overall performed really well, with the exception of the clutch slave cylinder. It went out on the C10 the night before the event and basically we did the entire event without a functioning clutch. However, we think that the truck will be back at it very soon, bigger and adder than ever before! We’ll bring you more on this one in the coming weeks.
