Meet the ultimate 1977 Chevy “moto van”—built specifically to haul vintage dirt bikes in style. This G20 is more than just a hauler; it’s a masterclass in period-correct modifications and incredible preservation.

Check out the details that make this van stand out:

• Custom Stance: We swapped in a narrower Trans Am rear end, allowing for those massive 18x10-inch deep lip wheels.

• Vintage Aesthetics: Rolling on ET Mags LT1 series wheels that capture that classic road race look.

• Time Capsule Exhaust: Thanks to its life in the dry Arizona climate, this van still runs its original 1977 factory dual exhaust—mufflers, welds, and all.

• No Catalyst Needed: Because this 3/4-ton G20 was rated as a truck in ‘77, it came from the factory without catalytic converters.

• Custom Paint: Coated in a striking Nissan blue (Paint Code: FAK) to match my vintage Monark bike frames.

To handle the massive power of modern swaps—like a 632 Big Block, Hellcat, or Supercharged Coyote you need a chassis that can take the heat. That’s why every Schwartz Performance G-Machine truck chassis features:

• 6-Inch Tall Rails: Significantly taller and stronger than a stock frame.

• Maximum Torsional Stiffness: Engineered to eliminate the flex inherent in two-piece truck bodies.

• Track-Ready Strength: Built for those who want to push their trucks to the limit on the autocross or road course.

Don’t let frame flex hold back your high-horsepower build. Upgrade to the best in the business. 🛠️🏁

Old School Look, Modern Power

Out with the plastic, in with the performance! 🏎️

We’re transforming this modern 392 Chrysler Hemi for a ‘56 Plymouth by swapping that factory intake for a low-profile Holley single plane.

We’re even modifying the original 1956 oil bath air cleaner to fit a modern K&N element for that perfect retro aesthetic with modern-day reliability.

Who says you can’t have the best of both worlds? 🛠️🔥

If you’re building an early Chevy or Ford truck, you know the struggle: vertical factory seats, 5 inches of bulky padding, and a steering wheel right in your gut.

Here is a pro tech tip to get that “sports car” feel without cutting out your original welded seat base:

• Ditch the Springs: Cut off those old-school coil springs.

• Fabricate a Seatpan: Build a new pan from metal or plywood. Pro Tip: Drill holes so the air can escape your high-density foam!

• Create an Artificial Incline: Use slim high-density foam at the top and thicker padding at the bottom to incline your seating position without moving the frame.

• Dish It Out: Shape the padding to sit lower, giving you plenty of legroom—even with a factory-sized steering wheel.

Check out the suspension tech on this ‘55 Chevy build. We use needle bearings and Teflon-lined rod ends on our G-Machine chassis to eliminate friction.

• ✅ Superior ride quality

• ✅ Instant reaction to road imperfections
