The Builder
Precision is personal.
Robert Moruzzi has built race engines for SoCal desert trucks his whole life. Every long-block is blueprinted, balanced, and proven on the dyno before it ever turns a tire.
Ten years in, the shop runs on the same obsession with detail it started with in 2014 — and a commitment to doing it right, not just fast.
— Robert Moruzzi, Builder & Owner
