1977 Chevy C10 - Savin' Cash, Goin' Fast

Class 8 Chevy On A Working Man's Budget

By Jay Kopycinski, Photography by Jay Kopycinski

Scott McCracken grew up riding and racing dirt bikes. A few years back he decided he wanted to build up a go-fast truck for fun and to try his hand at some desert competition. He put the word out that he was looking for a base truck for the project and a friend soon pointed him to a source that had what he was seeking.

Scott ended up buying basically a basket case 1977 Chevy C10 truck in 2005 that had formerly been a working prerunner but was in the middle of some suspension modifications when the previous owner decided to move on to another project. Once Scott hauled it home on a trailer, he set out by removing most of the front end of the truck and started redesigning it the way he wanted.

Where we, and probably many of you, can relate is the desire to build up a cool project and do so on a budget short of what it costs to fly to the moon. This was Scott's plan as well. To keep costs down, he had planned to do most of the work himself, including all the mechanical, chassis, fabrication, and welding. He did have a few ace cards that would make achieving his goal easier. Scott designs and builds industrial machinery, works in the metal fabrication industry and around some well-known builders. Cutting Edge Manufacturing, where he works, does all manner of CNC work, including laser cutting and forming, so he does have access to some excellent tooling to turn his metal ideas into reality.

When he started, he knew little about building a truck of this nature but did a lot of studying and asking questions to friends and fellow fabricators. Being a mechanical engineer by trade, Scott is adept at designing and modeling with Pro/ENGINEER 3D CAD software, so most everything was designed and checked on a computer screen before metal parts were cut and welded.

  • This shot gives you an overall look at the front suspension workings. First, a subframe from steel plate and DOM steel tubing was built, and integrated under the stock front frame rails. Lower A-arms attach there. All suspension and steering components were 3D CAD designed and laser cut, and then TIG welded to form the complete structures. The uprights mate to the upper and lower A-arms through uniball spherical bearings to allow for plenty of rotation for the suspension and steering movement. The front hubs are from a Ford F-150 4x4, and the spindles were custom machined from billet to mate the uprights to the Ford hubs. The front vertical travel is limited to 21

  • One typically expensive part in a build such as this can be the rear axle. Cash in five-figure amounts can disappear from you wallet if you want to source a serious race-built assembly complete with trussing, aftermarket shafts and all the other internals. Scott found an alternative that could still provide a beefy axle without breaking the bank. Scott took a salvage Chevy 14-bolt full-floater axle, and rebuilt and modified it for his needs. Down below, a skidplate attaches underneath and to a ring bolted to the pinion snout.

  • We liked this interesting bolt-on bridge truss that ties across the rear differential housing. It is easily removable to allow access to and removal of the differential cover. Rear axle gearing is 5.13:1 and a welded stock carrier rides in the pumpkin to keep the power making traction at both tires. The total weight of the 14-bolt rear axle with brakes is about 360 pounds.

This truck took a few years to build given the financial constraints and Scott doing almost all the work himself. He made a parts list of components he knew he would need and was vigilant to shop for used parts or discounts that could bring in the parts he needed while minimizing the cash that left. He advised us that patience pays and it takes time to build, so look for good deals along the way.

Scott's already tried the truck out in a couple of races, placing second in class in the Whiplash Vulture Mine race and fourth overall in the Whiplash Firebird GP. He's looking forward to doing more racing regionally and in Best in the Desert races.

With the truck up and running, and starting to compete, it looks like Scott met his goal to build a DIY capable racer on a budget within reach of many of us. Maybe you'll build one too!





  • Braking on all four corners comes from Coleman Racing four-piston NASCAR calipers clamping onto 13-inch Coleman rotors. Scott stops the truck with a pair of Tilton master cylinders, a 7/8-inch bore for the front calipers and 3/4-inch bore for the rears. Hard steel and stainless braid lines are used throughout.

  • Out back, the upward suspension travel is limited with the help of 2.5 4-inch travel King air bumps. Each hydraulic bumpstop's can has been welded to the outside frame rail and meets up with a landing pad on the top of the trussed axle tube.

  • Behind the engine sits a TH400 auto tranny. Scott installed a manual valve body and fabricated a custom rear crossmember to support the tail. Driveshaft U-joints are 1350 series pieces and the tranny has a fixed yoke output, which is stock on a 1-ton version tranny. Shifting is handled using an Art Carr gated shifter.

  • The lower rear trailing arms are built from 2-inch 0.120 wall chromoly tubing and boxed in with 0.125-inch chromoly plate that is doubled up near the lower shock eyes. 1 1/4-inch rod ends hold the links to brackets on the axle housing and framerails. The rear suspension and axle fab work was done with an eye towards building the strength required for the abuse they will receive, while living with the relatively heavy weight of the 14-bolt as a tradeoff for low cost. The upper links were constructed from 1 3/4-inch 0.120 wall chromoly tubing. You can also see that the stock Chevy frame rails were fully boxed using plate steel to keep them from flexing more than they should.

  • The upper front shock mounts are tied into the engine cage structure. A 2.0 14-inch stroke King coilover is assisted by a 3.0 14-inch stroke 3-tube King bypass shock to keep each front tire under control in the rough stuff. To slow the final suspension travel and limit upward movement, a 2.5 King air bump is used. Scott modified its top end by adding a 3/4-inch rod end to allow it to swivel, while the lower end moves on a slapper arm to keep it squarely tracking the upright landing pad as it moves through its arc of travel.

  • The rear of the truck is supported by a pair of 2.5 14-inch stroke King coilovers. Damping is provided by a pair of 3.0 14-inch stroke six-tube Mike Smith bypass shocks that Scott's using on loan until they can be replaced with 3.0 16-inch stroke King units. The new bypasses will allow the rear suspension to reach the design goal of 27 inches of travel.

  • Behind the cab sits a ducted cooler assembly that holds two units: one for transmission fluid and the other for engine oil. Supplementary fans were added for those hotter races. Below the fans sit a pair of Optima batteries. A Red Top provides juice to crank the motor and a Yellow Top serves as a deep-cycle backup.

  • Nestled in the back of the bed cage is a 32-gallon Fuel Safe cell feeding the thirsty engine with high octane pump gas. A Holley electric fuel pump sits just forward of the fuel cell.

  • Behind the front tubework and Hella lights sits a Jeg's aluminum radiator. The alternator on the engine was upgraded to a late model 130A unit to help keep the lighting bright. An additional light bar can be added to the roof of the truck if much darkness is anticipated.

  • With the hood popped off the truck you get a glimpse of the engine cage that protects the small block Chevy V-8 and provides added support for the front suspension. A 350 V-8 was used, but freshened up and is a bit warmed over with the addition of a set of World Products SR Torquer heads that Scott ported/polished and blueprinted. Comp Cams roller rockers are pushed by a Comp XE hydraulic cam. Induction comes via an Edelbrock Victor Jr. intake topped with a Holley 750 double-pumper carb. Ignition chores are handled with an MSD billet distributor and 6AL ignition module. A Canton oil pan with wingdage screen helps keep the oil cooled and down in the sump at all times. A bigger, badder motor is in the works and will be finished as funds allow.

  • Inside the cab, Scott fabricated a functional dash to accommodate a full set of Autometer Pro Comp liquid filled gauges, PCI intercom, Icom race radio, and the wide array of switches need to control everything from ignition to cooling fans to lighting. A Lowrance 540C GPS system sits forward of the co-driver for course navigation. The layout is well thought out and the wiring is clean, something you don't always see on off-road vehicles.

  • The homebrew goodies show up in the cab as well. Scott fabricated the throttle pedal and brake pedals from scratch. No vacuum brake booster is used on the brake masters to simplify the system and keep braking force consistent under all conditions. Scott built the brake arm a bit longer than normal to help increase leverage and reduce the leg effort needed to bring the truck to a stop.
