Custom Builds: Bespoke Engine Solutions Tailored to Your Vision

Custom Builds.Not every project fits neatly into a standard crate engine catalog — and that’s exactly why our Custom Builds program exists. Whether you’re restoring a classic show car, chasing quarter-mile records, or repowering a boat that deserves better, we build engines around your goals, not the other way around.

Your Project, Your Engine, Your Way

From Small Block and Big Block Chevy to LS Series, Ford Windsor/Coyote, and Mopar HEMI platforms, every build starts with your specs. Choose your block, crankshaft, pistons, camshaft, cylinder heads, ignition, and dress-up components — nothing is one-size-fits-all here.

Four Ways We Build Custom

1. Custom Crate Engines — Unique displacement and component combinations you won’t find pre-built anywhere else.
2. Dyno-Tuned Performance Packages — Every engine goes through a proper break-in and power pulls, with a printed dyno sheet showing your real horsepower and torque numbers.
3. Complete Turn-Key Packages — Engine, ECU, wiring harness, fuel system, cooling, exhaust, and installation support, all bundled together.
4. Marine Custom Builds — Saltwater corrosion protection, closed cooling systems, and marine-grade fuel and ignition components for boat owners with specific repower needs.

A Process Built on Transparency

Every build follows seven clear steps: consultation, component selection, quotation and approval, assembly, dyno testing and tuning, final inspection, and delivery. You’ll get complete documentation along the way, including your build sheet and dyno results.

Ready to stop settling for catalog specs? Fill out the project details form with your vehicle or vessel, engine family, horsepower goals, and budget, (Custom Builds) and our team will follow up with a tailored quote.

Not every project fits a standard crate engine catalog. Whether you’re building a show-stopping classic car, a high-performance race machine, or a one-of-a-kind marine vessel, we offer custom engine solutions tailored to your exact specifications.

From dyno-tuned performance packages to complete turn-key builds, (Custom Builds) we bring your vision to life with precision engineering and unparalleled expertise.
