"The Engine"

 Custom engines for RVs and automobiles are kept to very high tolerances. Each engine is disassembled, cleaned and inspected. Cylinder heads  have new  guides  installed and  hand  honed  for clearance. They are checked with a bore gauge and  will stay within .0002" on clearance specifications.  Hardened  exhaust   seats are installed to allow for long life with today's fuels. Seats are machined with a radius cutter allowing for maximum flow. The heads are trued and assembled  with spring pressures set to precise specifications. The block is align honed and decked with a fixture  to keep the deck surfaces perpendicular to one another. The piston to deck clearance is very close to zero thousandths keeping combustion travel more efficient by getting more burn in the combustion chamber of the head. The cylinders   are bored and honed with torque plates to simulate heads bolted on to block during process. Connecting Rods are reconditioned and the engine assembly is balanced. The same procedure performed to balance race engines!  Then the assembly begins.
