1968 Chevy C10. Built different. This one’s got an LT4 backed by a 10-speed transmission pulled straight from a 2023 Camaro ZL1, full drivetrain swap, done right. Built by our good friends at LBJ Collision , planned together every step of the way. We handled the tuning here at Yellowhammer Racing. No expense spared, tap shift with a floor shifter straight from a Camaro, and she drives like a brand new truck.

2012 Chevrolet Corvette C6 came in with a bad lifter tick and a rough misfire. Tear down revealed a collapsed lifter and a worn cam — so we went all in. BTR Stage 2 camshaft, Delphi lifters, new pushrods, trunnion kit, oil pump, and head gaskets. Back together and onto the dyno, she pulled 404 hp and 391 lbft to the wheels. From dying to thriving!

2019 Dodge Charger 392 rolled in misfiring and running rough after the customer tried everything — ignition coils, spark plugs, even a replacement PCM. No luck. Our diagnosis found the real issue: Hellcat injectors and throttle body were on the car, throwing everything out of sync with the factory tune. We went back to basics — OEM spark plugs and coils, because factory still beats aftermarket here — a fresh set of catalytic converters ruined by the misfire, and a custom tune built around the Hellcat hardware. Problem solved, right the first time.

2026 Cadillac CT5 Blackwing rolled in with under 1,000 miles for a supercharger lid upgrade. We installed the FLHP Carbon Fiber LT4 Supercharger Lid — this one wasn’t about chasing power, it’s all about looks and that incredible supercharger whine. Fresh off the dyno, she still laid down 590 horsepower and 596 pound feet of torque to the wheels. Form, sound, and brutal performance, all in one package.

2024 Ford Raptor R just rolled off our dyno with a hundred more horsepower on tap. Upper pulley, custom HP Tuners tune, and a thermostat swap turned this factory monster into a certified weapon. This is what real gains look like.

2013 Cadillac CTS-V | Serious Power Incoming.

This CTS-V came in for a major transformation. We’re installing a Kong Performance 2650 supercharger with a 112mm Kong throttle body, reinforced intercooler brick, ID1300 injectors, a full return-style fuel system, fresh spark plugs, and a high-torque mini starter to eliminate the dreaded CTS-V slow-start issue. We’re also inspecting the battery, cables, and charging system to ensure everything is ready to support this setup.

With a built engine and built transmission, this combination is designed to make serious power while staying reliable. Once everything is buttoned up, it’s headed to the dyno to see what it can do.

Stay tuned for the final numbers. 🔥

2026 C8 ZR1 – Stock Dyno Numbers 📊

After all the guesses over the past few days, we put this 2026 C8 ZR1 on the dyno to see what it really does — completely stock.
No tuning. No changes. Just data.

Dyno graphs shown in SAE and STD correction, with axis displayed in vehicle speed and RPM for proper comparison.

• 1 pull in 4th gear (this is the video shown)
• 2 clean back-to-back pulls in 5th gear
• First dyno graph = 4th gear pull

Consistent, repeatable pulls and numbers that speak for themselves.
This was strictly for the people — now you’ve got real data to go with the guesses 👀
