LS & LT Swap Specialists in Vancouver, WA & Portland, OR
Premier Engine Swap Shop for GM Performance Builds
At Fast Specialties, we’ve spent the last two decades building a reputation as the go-to LS swap shop in the Portland and Vancouver area. From budget-friendly junkyard 5.3 truck motors to six-figure restomods with show-car finish and modern drivability, our team has completed more GM LS and LT engine swaps than most shops in the Pacific Northwest. If it involves a General Motors V8 platform, we’ve built it, wired it, tuned it, and tested it.
What Does and LS or LT Swap include? — From Planning to First Startup
We don’t just “install an engine.” We handle the entire process end-to-end, including:
- Engine and transmission fitment
- Custom mounting solutions
- Fuel system upgrades
- Cooling system design
- Accessory drive setup
- Exhaust and light fabrication work
- Wiring harnesses and ECU integration
- Dyno tuning and drivability refinement
Whether you want to keep it simple with a stock truck 5.3 or chase 1,000+ horsepower with forged internals and boost, we have the experience to help you choose the right parts, avoid common pitfalls, and stay on budget.
Factory ECU, Holley Terminator, or Standalone — We Tune It All
One of the biggest advantages of working with Fast Specialties is that we’re not married to a single system. We tune and support:
- Factory GM ECUs (Gen III, Gen IV, Gen V)
- Holley Terminator X & Terminator Max
- HP Tuners–based builds
- Holley EFI / Dominator
- Link, MegaSquirt, and other standalone ECU solutions
We’ll tell you exactly which systems work best based on your goals, vehicle type, and budget. Some parts are worth saving money on — and some aren’t. We’ll be honest about which is which, based on real-world results from hundreds of LS swap projects we’ve built or tuned.
Your Build, Your Goals, Our Expertise
Every LS swap is its own adventure. We help you determine:
- Realistic horsepower goals
- Which components you can reuse
- Where to invest in quality parts
- Which budget options actually hold up
- What combinations deliver the best power per dollar
Our experience saves customers thousands of dollars by avoiding parts that don’t perform, don’t fit, or don’t work well together. If you reach out early in the planning stages, we can help design your build from the ground up — saving time, money, and frustration.
