Welcome to Overbore.com
The Premier Automotive Engine
and Machine Shop On The Web

Overbore is proud to invite you to experience our facility to the fullest. We are a full service machine shop specializing in Sport Compact Engines. Our standards are far greater than the original factory specs. We can rebuild, overhaul or replace any and all engines from any manufacturer. Overbore has all that it takes to complete your project car, hot rod, race car or tractor overhaul.

Every engine we build begins with a thorough cleaning, inspection and machining of all re-manufactured castings. All cast iron components are magnaflux to guarantee integrity. Engine blocks are precision bored, decked and honed to the specified RMS. Crankshafts are ground and polished to an 8-12 RMS finish. Valve seats are precision cut to three angles, and heads are resurfaced and vacuum tested. The following components are replaced as part of the manufacturing process:

  • Pistons
  • Rings
  • Timing Components
  • Freeze Plugs
  • Installer Gasket Set
  • Main Bearings
  • Rod Bearings
  • Cam Bearings
  • New or Reground Cam Shaft
  • New Push Rods
  • Hydraulic Lifters
  • Oil Pump
  • Re-machined Block, Crank Shaft, Connecting Rods and Cylinder Heads

Nothing is left to chance. Our quality machining process would be wasted if we didn't also use the finest engine parts available. Call us today for an estimate or request one from our online form.
