Man..these things just make sense!

This 2023 Challenger Hellcat Jailbreak A8 came to us looking for some easy, reliable power without changing driveability. After a brief consultation, our signature 750rwhp package was the perfect fit for this visit. This package focuses on safe, sensible upgrades without changing driveability, reliability or becoming too invasive. We ditched the OEM supercharger pulley for the ZPE/GripTec 2.85in pulley & hub combo, along with a set of Fuel Injector Clinic 1000cc injectors for adequate fuel flow and lower duty cycles. We also added a MightyMouse Solutions catch-can for increased crankcase ventilation along with a Brisk Racing spark plugs. With expert tuning from Evolution Tuning & Performance, this simple package leaves our dyno making 754 rwhp and 675 ft lbs on a safe tune. Not bad for a mildly built Hellcat!

Check out this 1971 International Scout II that came through the shop for a complete LS swap!

Originally powered by the factory 345ci International V8, this Scout made just 95 RWHP. We replaced it with a Chevrolet Performance LS3 backed by a GearStar Level 3 4L65E automatic transmission, boosting it to 321 RWHP and 363 lb-ft of torque at the wheels.

Along with the swap, we installed a CVF Racing Reaper serpentine drive system, built a custom TIG-welded stainless exhaust, rewired the entire vehicle, added air conditioning, custom Wegner coil covers, an ididit tilt steering column, 3-point seat belts, LED tail lights, and more. The result is a classic Scout with modern reliability and performance.

Thinking about a modern powertrain swap? Slate Performance Automotive has completed Gen III HEMI, Coyote, LS, and LT swaps in both classic and modern vehicles. From fabrication and wiring to installation and tuning, everything is done in-house to ensure your build is done right.

Built for the street, ready for anything! 💪🇺🇸

This bone-stock 2014 Corvette Stingray came to us wanting a “gold-standard” N/A power package, and is leaving having surpassed expectations. Putting down 405 RWHP / 411 lb-ft of torque from the factory, this Corvette is the perfect canvas for a complete transformation. After a brief consultation, we relied on our friends at Brian Tooley Racing as the foundation of the build with their signature 225 cam kit. After all is said and done, this Corvette leaves the shop with an impressive 545 RWHP / 506 lb-ft of torque on a conservative tune. 🔥

Build Highlights:
🔧 OEM short block overhaul & rebearing
🔧 Brian Tooley Racing 225 cam & valvetrain package
🔧 Gwatney Performance ported heads
🔧 MSD Atomic AirForce intake manifold with Nick Williams 103mm throttle body
🔧 Cordes Performance 4.5” cold air intake
🔧 McLeod RST twin-disc clutch kit
🔧 MightyMouse C7 catch can kit
🔧 Stainless Works 1-7/8” long tube headers

That’s a gain of +140 RWHP and +95 lb-ft of torque—transforming this C7 into an entirely different machine while maintaining street-friendly drivability.
