What we do

Services

From a check engine light to a fully built, boosted street truck — every job goes through the same process: diagnose it honestly, quote it clearly, build it right.

Classic Car Restoration

Complete custom builds for classic cars and trucks.

Full frame-off and restomod builds on older cars and trucks — paint and body, chassis and suspension, brakes, interior, wiring, modern drivetrain and A/C. Show-quality finish work with modern reliability underneath.

Complete Auto Repair

Full-service repair for everything you drive.

Diagnostics, brakes, suspension, electrical, cooling and drivability work — done right the first time with a straight answer before we touch a wrench.

Performance Upgrades

More power, built to hold up on the street and the strip.

Cam packages, heads, headers, fuel systems, boost and supporting mods with calibration so the power is reliable, not just impressive.

Powertrain Swaps

LS, LT, Coyote and Mopar conversions — factory harness and ECU integration.

Modern V8 and V6 swaps into older cars and trucks: LS, LT, Gen 3 Coyote, and Mopar HEMI platforms. We handle mounts, fuel, cooling, accessory drives, wiring and tuning so the swap looks factory and drives like a new car.

ProCharger Sales / Install

Authorized ProCharger sales and professional installs.

Centrifugal supercharger kits sold, installed and tuned with the supporting fuel and cooling upgrades to back them up.

BG Services

BG fluid and maintenance services that extend engine life.

BG induction, fuel system, transmission, coolant and oil services to keep your vehicle running clean and protected.

Powertrain Platforms

Modern engine conversions for classic cars and trucks — built to drive, tuned to last.

GM LS

5.3L, 5.7L, 6.0L, 6.2L — the go-to swap for restomods and muscle cars.

GM LT

Direct-injected Gen V power for the latest LS-class builds.

Coyote

Gen 3 5.0L and 10R80 swaps into Ford muscle, trucks and classics.

Mopar HEMI
