🔥 Holy boost, Batman! This LSX 454 just woke up with some SERIOUS attitude! 🔥

We dropped a Whipple Superchargers GEN 6 3.0L Inverted Hot Rod supercharger on top and dressed it out with a razor-sharp Concept One Pulley Systems Max 10R 10-rib pulley system. That inverted Whipple sits nice and low for perfect hood clearance while the dedicated 10-rib belt laughs at big boost.

Big shoutout to little Miss C, our newest shop intern — she helped her Dad with assembling the motor and made sure every billet piece was gleaming. First day on the job and she’s already wrenching on 1,000+ horsepower builds. Future is bright with this one! 👏

This beast is built to deliver massive torque that’ll pin you to the seat the second you mash the throttle. Instant grin every single time.

Clean billet looks, twin-screw whine, and enough low-end grunt to destroy tires in any gear. Street car by day… tire-shredding monster by night.

Who else is running a big-inch LS with a Whipple?

Drop your combo, your peak boost, or just a 🔥 if you’re feeling this one!

Father and son LS3 Camaro 68 conversion project in Iceland!

This is a full documentation of our epic father-son build: swapping a modern LS3 engine into a classic 1968 Chevrolet Camaro. After two years of careful planning, we completed the entire project in just four months — with most of the work done by us, with a little help from a few good friends.

We handled the suspension, steering, brakes, cooling system, fuel system, and even upgraded the gauges in the dash. All the key parts were supplied by John Tucker at Southern Performance Systems (SPS), who delivered incredible support and quality — something we really needed living all the way out here in Iceland, far from the US.

The result? A stunning classic Camaro that drives like a modern sports car, while still keeping that raw, authentic muscle car character.If you love restomods, LS swaps, or father-son garage projects, this one’s for you!
