Why Competition Machining

Built different.
Built to win.

We're a real machine shop staffed by people who understand what it takes to compete. Every job gets the same attention — whether it's a single valve job or a full engine build.

Competition-Grade Precision

Every dimension is held to tolerance. We work on engines that race — so we hold ourselves to race-level standards on every single job, not just the big builds.

All In-House

We don't outsource machining. Block decking, boring, honing, balancing — it all happens in our shop under our control, so you get consistency and accountability.

Straight to the Point

You'll get an honest assessment and a real quote — no upselling, no runaround. Call us, describe the job, and we'll tell you exactly what it takes and what it costs.

Dyno Data, Not Guesses

Every complete engine build we do goes on the dyno before it leaves. You get numbers — power curves, torque figures, break-in data — not just our word that it's ready.

Real Shop Experience

We've been building and machining competition engines for decades. Our team has track experience — we know what actually fails under race conditions and how to prevent it.

Local, Accessible

Based in New Milford, CT — close to the racing community in the Northeast. Come see us at the shop, call, or email. We're easy to reach and respond fast.

How it works

Our Process

Whether it's a single machining job or a full engine build, here's how we work — clearly and without surprises.

Step 01
Consultation

Call or email us with your engine specs and goals. We'll assess the job and give you a clear quote upfront — no hidden costs.

Step 02
Teardown & Inspect

We inspect, and clean every component before any machining begins. Nothing gets rushed if something else we'll bring it to your attention.

Step 03
Machine & Build

All machining is done in-house. Engine builds are assembled to your specification with competition-grade precision and quality parts.

Step 04
Test & Deliver

Every complete engine build is dyno tested before delivery. You get real data — power curves, torque figures — not just a promise that it's ready.
