  • The Right Engine

    Matching the engine to the vehicle, your goals and your budget, whether that is a junkyard LS, a crate engine or a rebuilt original.

  • Mounts and Transmission

    Engine and transmission mounts, adapters, driveshaft length and clearance for oil pans, headers and the firewall.

  • Wiring and Engine Management

    A clean harness and engine computer setup so the swap starts, idles and drives like it came that way.

  • Fuel System

    Pump, lines, regulator and filter sized for the new engine, whether carbureted or fuel injected.

  • Cooling

    Radiator, fans and hoses that can handle a bigger engine in Texas heat.

  • Exhaust

    Headers or manifolds and an exhaust system that fits the chassis.

Noticing any of these?We diagnose first and give you a written estimate before any work begins.

Swaps Done by an Engine Shop

A swap is only as good as its details: the wiring, the fuel system, the cooling and the mounts. Because we rebuild, repair and tune engines every day, we plan the whole package so the result is a vehicle you can drive, not a project that never gets finished.
