About this engine

Built to be driven, not to sit on a stand.

The STR-440 is our entry-level pushrod V8 built for restomod projects, weekend builds, and small-shop swaps. Cast aluminum block, forged crank, and a refined intake geometry deliver dependable street power that's affordable to maintain. Tuned for 91 octane pump gas, it shrugs off daily commutes and lights up the rear tires on demand.
