Shoprat Metal Works / Engine machine work

Machine work that earns its keep.

From tired cores to purpose-built combinations, the details are measured, checked, and matched to the way you plan to run it.

The approach

Built around the tolerances.

Engine work does not start with a parts list. It starts with an honest look at the block, heads, rotating assembly, and intended use.

Block work

Cleaning, inspection, boring, honing, decking, and prep that gives the build a straight foundation.

Cylinder heads

Valve work, guide service, surfacing, chamber attention, and the careful fit-up that makes airflow useful.

Rotating assemblies

Balancing and clearancing support for combinations that need to live hard, not just look good on a stand.

Shop standard

No mystery measurements.

  • Measure before deciding
  • Match work to the actual combination
  • Build for use, not a brochure
  • Keep the conversation straight

Bring the core. Bring the plan.

Tell the shop what you are building, how you use it, and what parts you have. Then the work can start in the right place.
