ACTIVE BUILD PROJECT: Get in now, shape the outcome!
Comes with a NHRA 2026 chassis cert 7.50
Car Description
This shop project is being set up as a small tire car, originally designed for a 10.5W setup — so anything smaller will fit right in. It features a full steel body, steel doors, fiberglass nose, and functional roll-up windows with glass, offering a solid, vintage base for serious performance.
- Our build vision includes a BBC, two stages of nitrous, a ATI Powerglide transmission, 9″ rear with 4:11 gears — all aimed at building a competitive, reliable drag car. That’s how we’d build it. The chassis has now been certified to NHRA 7.50 specs, making it track-ready for serious racers.

10-10-26 Project Update:
Exhaust Fabrication: Custom Hand-Welded 304 Stainless Steel Headers
When you are pushing heavy horsepower, off-the-shelf exhaust components simply won’t cut it. That is why this set of headers on the ’71 Opel build are meticulously hand-fabricated and custom-welded in-house using premium 304 stainless steel.
- Zero Rust, Lifetime Durability: Unlike standard mild steel headers that degrade, pit, and rust out over time from moisture and extreme thermal cycles, 304 stainless steel provides superior corrosion resistance. It is an investment that preserves its structural integrity and finish for the life of the car.
- Superior Thermal & Flow Performance: Stainless steel handles extreme exhaust gas temperatures far better than traditional materials, reducing thermal fatigue and holding up under aggressive race conditions. Each primary tube is custom-routed and TIG-welded to optimize scavenging and maximize exhaust flow, ensuring your Big Block Chevy breathes freely for peak horsepower output.
Custom Aluminum Interior & Flush Lexan Rear Window
Rather than using traditional, bulky pre-made tubs, we designed a completely unique rear aluminum interior layout that maximizes space, optimizes weight distribution, and provides clean lines around the rear suspension geometry.
To make service fast and efficient between rounds, the entire custom aluminum interior tin work—including the rear bulkheads and transmission tunnel panels—is secured with DZUS fasteners for rapid trackside removal. Paired cleanly with a flush-mounted Lexan rear window, the entire cockpit combines lightweight safety with high-end, professional-grade craftsmanship.
Custom Clear Air Scoop & Carb Hat Setup
To crown the powerhouse Big Block Chevy engine, this ’71 Opel build features a precision-fabricated, custom clear air scoop and carb hat assembly.
- Unmatched Engine Bay Visibility: Designed for builders and racers who want to showcase their induction setup without sacrificing functionality, the clear casing offers an unobstructed, crystal-clear look at the carburetor hardware underneath.
- Track-Ready Visibility & Airflow: Engineered to maintain proper airflow and pressure dynamics to the Big Block Chevy, this setup gives you another major added bonus on the track: the driver can look ahead and see the staging tree clearly without having to peer over a massive, obstructive traditional scoop.
9-30-26 Project Update
8-22-26 Project Update: The custom round-tube chassis is freshly finished in high-gloss black, and the steel body shell is rocking a deep, brilliant red. Here is where this active build stands:
- Chassis: Stamped with a fresh NHRA 7.50 Chassis Certification.
- Fabrication: Full TIG-welded round-tube chassis, rack-and-pinion front end, and custom aluminum tin work.
- Body Setup: Factory steel body and doors with functional roll-up glass windows paired with a fiberglass nose.
- Powertrain Potential: Configured to handle a Big Block Chevy (BBC) with two stages of nitrous, Powerglide transmission, and a 9″ rear end with 4:11 gears.
- Tire Clearance: Set up for a 10.5W tire — meaning any small tire configuration fits comfortably!

- 12-24-25 UPDATE: The night before Christmas…
- 11-25-2025 UPDATE: Chassis is almost ready for NHRA 7.50 certification.
- 10-25-2025 UPDATE: Don’t wait to make this YOURS. Don’t second-guess. With every spark the welder — you’re paying more.
- 7-11-2025 UPDATE: Chassis Pipe Just Arrived! The 1971 Opel drag build is officially in motion — pipe’s here, jig table’s ready, and this small tire BBC setup is about to take shape. Want to make it yours? Now’s the time to lock it in and build it your way. Once we start cutting and welding, the price goes up.
January 18, 2019: The Opel is called the “poor man’s corvette” this is a cool car in a small package. This project has many options – and could be next on the JIG table. Buy it now or wait tell it’s finished.
