Curt Shumaker, who owns Premium Truck and Auto Body in Ortonville, Michigan, is a lifelong Sprint car racer who recently caught the rodding bug. He wanted to build an older pickup as close to stock body and upgrade the interior and drivetrain. Curt also wanted to put his company's logo on the side of a piece of restored automotive history and cruise it around to show off the shops great workmanship, sort of like a rolling business card.
Curt started building rods a couple years ago. His first was a 1930 Ford two-door sedan that made the pages of Street Rodder magazine when Editor Brian Brennan spotted it parked next to this truck at the 2010 Autorama in Detroit. Curt started the truck one year after he began work on his street rod, but managed to finish them at the same time.
The Ford was found in pieces at an NSRA event in Kalamazoo, Michigan. Someone had started the project but couldn't finish it. As it turned out, the Ford was the perfect truck for Curt's project. The truck created an opportunity for Curt's body shop to receive a lot of attention at Detroit's Autorama and show that his body shop can do custom quality paint and body work. Rods are such good conversation starters; Curt spent all his time at Autorama talking to people about building and painting cars.
The build on the truck started by boxing the frame to stiffen it a bit more for the small-block Chevy that would be powering it and installing a Ford 8-inch rear end with a 3:43 gear suspended on a monoleaf fiberglass rear leaf spring with Monroe shocks and Ford rear drum brakes.
The independent front suspension is a Fat Man Fabrications Mustang II style with a 2-inch-dropped axle and Hypercoil springs and Monroe shocks. The steering is a Mustang II box with an ididit steering column and a Grant alloy steering wheel. Curt upgraded the front brakes to late-model GM discs with an inboard frame-mounted master cylinder, power booster, and a brake-proportioning valve.
The driveline for Curt's truck is based on a GM Performance Parts crate 350 that Curt had Butch Dowker blueprint, balance, and lightly modify. The goal was reliability with good power throughout the full RPM range. The SBC has RHS aluminum heads with a Comp Cams Thumper series cam. The crank is a Lunati with Oliver steel rods and Diamond 9.5:1 aluminum pistons. The Holley 650 carb is sitting on a GM Performance Parts aluminum manifold. The spark is provided by MSD with Mallory wires. The headers are Shoenfeld and breath through a 2 1/2-inch exhaust to Turbo mufflers. The end result is a great all-around engine with 360 hp and 410 lb-ft of torque.

Based on a GM crate motor, Curt had Butch Dowker swap out the heads for some RHS aluminum units and slid in a Comp Cams Thumper Series stick to add a little more power. The engine makes 360 hp and 410 lb-ft of torque, more than enough power to make this truck a blast to drive.
That power gets channeled through a mildly modified GM 700R4 built by Jeff Aldrich from Grand Blanc, Michigan. Jeff installed a 2800-rpm stall converter and a shift kit in the trans with a Lokar floor shifter handling the gear selection.
The 1937 Ford pickup Curt started with is a hard model to find parts for. The grille and stainless steel trim parts are not reproduced along with most of the sheetmetal. It's the last year with a side-opening hood and a radiator grille shell on Ford trucks. The year 1937 was the first year for Vee windshields to be on all Ford vehicles too.
