Engine Swaps & Rebuilds
Full motor pulls, replacements, and rebuilds. We source, we build, we make it roar.

Full-service auto repair and custom builds in Ontario, CA. From the legendary Crown Victoria and modern Police Interceptors to everyday drivers — engine swaps, transmissions, suspension, brakes, and diagnostics by hands that know their way around any engine.
Crown Vic Guys isn't a repair shop. It's the last stop for Ford's finest law-enforcement iron. We started with the legendary Crown Victoria — the P71 Interceptor, the civilian cruiser, the workhorse that refused to die.
Today we carry that legacy forward into the modern era: the Ford Police Interceptor Sedan and Utility, alongside the classic P71. From full engine swaps and transmission rebuilds to suspension geometry and custom fabrication, every build leaves this shop with the kind of precision you can only earn from doing one thing for a very long time.

Two eras of Ford police iron. Total dedication. If it bolts onto a Crown Victoria or a modern Police Interceptor, we know how to make it better.
Full motor pulls, replacements, and rebuilds. We source, we build, we make it roar.
Rebuilds, replacements, and tuning for the 4R70W and beyond. Smooth shifts, built tough.
Lowering kits, control arms, and geometry that turns a boat into a corner-carver.
Pads, rotors, lines, and full brake overhauls. Because stopping matters more than going.
Diagnostics, alternators, starters, and the full electrical system that keeps it alive.
Ground-up restorations and one-of-one fabrication. Bring the vision — we build the car.



"These guys brought my '06 P71 back from the dead. Engine swap was clean, transmission shifts like new. Only shop I trust with a Crown Vic."
"Took my Vic here after three other shops shrugged. They diagnosed it in an hour, fixed it in two days. Honest, fast, and they actually know the car."
"Custom build was better than I imagined. Suspension work turned my boat into something that actually corners. These guys are artists."
