Engines
               We supply racing engines for WKA, IKF and Mini Cup racing.  Our engines are
            machined with Bridgeport milling machines, Sunnen cylinder honing products,
          Kwik Way valve seating tools.  The machined surfaces are measured with a
       profilometer to ensure the highest quality surface finishes.  Our cylinder heads are
     flow tested on a Superflow 300 air flow bench to ensure the cylinder head will make
    the power your looking for.
