We put this car together probably 7–8 years ago for one of our great customers. At the time, we installed a Vengeance Racing camshaft, full Kooks headers and exhaust, and deleted all the EGR and AIR junk.

Fast forward a few years and this one came back in for a checkup after the customer noticed a slight noise underneath.

We found a broken exhaust hanger, got that repaired, went through the tune-up to make sure everything was still running right, and sent it back on its way.

It’s always cool seeing old projects come back through the shop. Kind of like getting a visit from an old friend you haven’t seen in years.

We love “Round 2” projects. There’s nothing better than building something for a customer and having them come back wanting more!

This LS3/6L80E C6 came to us last year for a full exhaust, camshaft, and converter setup. At 425 rwhp, the car was already about perfect for a street car.

A few months back, the customer got ahold of us and asked what we could do next for a bit more.

We decided to take it to the next level with an A&A Supercharger kit, along with a few of their upgrades, a 525 LPH fuel pump setup, remote transmission cooler, and a P3 gauge integrated into the dash.

Now, running 7.5 lbs of boost, we picked up another 200 whp!

The result? An absolute animal on the street. It sounds nasty, drives hard, and now has 626 rwhp on tap.

The only question now is…

What does Round 3 look like? 👀

Not our usual build, but hey, the Gen 3 Hemi deserves some love every once in a while too.

This ’15 Ram came to us with a hurt 5.7L, and the owners knew they wanted something bigger and better. Rather than just adding a supercharger to another 5.7L, we decided to go straight to a 426ci Hemi.

We ordered a BluePrint Engines 426ci and got to work making it happen in this Ram. We added a set of Stainless Works long tube headers, a Holley Hi-Ram intake manifold, and built a custom intake tube to the Volant air box. We also added a Circle D converter to the 8HP transmission to help put the power down.

All finished up, the 7.0L is now making 455 rwhp, a noticeable gain over the stock 5.7L.

If you’re looking to upgrade your Gen 3 Hemi-powered Ram, Charger, or Challenger, let us know. We can put together a package that fits your goals and turns your hot rod into something special.

We were heavily involved in the powertrain, wiring, and plumbing on this high-end build of a ’59 Chevy truck.

From the complete chassis wiring harness, Dakota Digital instrumentation, and Vintage Air A/C system to the LS3/6L80E swap, we handled it all. We also built the fuel system, Wizard cooling system, and custom 3” stainless exhaust in-house.

Fine Toone Customs took care of the bodywork, paint, and final assembly, and it turned out great.

Now the owner can finally enjoy this long-time build, all wrapped up and ready to cruise!

What’s cooler than having one Lincoln Continental in the shop? How about a pair of them?

The ’64 on the hoist came in for a few tweaks to the air ride system. It had a leak causing it to settle overnight, along with a few wiring issues. We’ll see this one back later this winter for some additional wiring upgrades around the LS3 swap.

The one behind it was in for some tuning on its LS swap as well.

These cars are just badass!

This wild Gen V Camaro came in for a few upgrades and a tune check. Power comes from a Thompson Motorsports 427ci engine topped with Frankenstein cylinder heads and a billet intake manifold.

After discovering a failed rocker, we took the opportunity to upgrade to a shaft-mounted rocker system for improved durability.

Boost is supplied by an F1A-94 ProCharger, and with the smallest pulley installed, the combination makes right around 20 psi.

The drivetrain features a full manual JH-built 4L80E transmission backed by a DSS 9-inch rear end. Engine management is handled by a MoTeC M150, which works with the factory wiring harness so all of the OEM gauges work without issue.

After dialing everything in, the Camaro laid down just over 1,000 horsepower at the wheels on our hub dyno.

On street tires, it’s an absolute handful!
