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.

Sometimes...the simplest modifications are the best.

This beautiful 2024 Porsche 911 Turbo S came to us looking to upgrade the existing valved exhaust for some added sound and performance. We partnered with Soul Performance for their 992 valved exhaust system, which perfectly complements this Porsche. The valves operates off of OEM systems & mapping, giving you the dynamic sound and performance your Porsche deserves.

Check out this 1969 Chevrolet Camaro powered by a Pat Musi 565c.i. big block Chevy! This restomod is packed with a lot of great upgrades including an FB Racing 4R70W transmission, a Holley Terminator X standalone EFI management system, every Detroit Speed suspension component, LED taillights, and custom three-piece Forgeline wheels with a fat 335 rear tire. This car recently came in for a list of repairs & upgrades. To start (literally), this car needed a new starter & flexplate. We replaced the existing flexplate with a billet steel PRW flexplate and paired it with a 400 series Meziere High Torque Starter. While the car was here we also repaired the custom-fabricated oil pan, replaced the rear main seal, wrapped the headers, flushed the cooling system, repaired some wiring, and fixed miscellaneous leaks. For upgrades, we installed a set of Holley Retrobright LED headlights, replaced the steering column with a Flaming River tilt column, installed some Morris Classic 3-Point Seatbelts, and installed matching key tumblers. Once all repairs and upgrades were complete, we strapped this big block behemoth to the dyno to measure the rear wheel horsepower & torque. This naturally aspirated 565c.i. BBC put down 582 RWHP and a staggering 806 lb/ft. of RWTQ! Whether you want to do some knarly burnouts, go for a nice sunday cruise, be a show stopper, or set great times at the drag strip, this car will do it all!
