Engine Installation Guide
Things to do and know before installing your new engine.

Before Installation Checklist
Be sure to inspect the following components for condition and proper operation:

• Engine & Transmission Mounts & Bolts
• Pulleys
• Radiator (Is your radiator cooling properly? It may need to be flushed by a professional radiator shop.)
• Oil cooler lines (check for debris)
• Alternator
• A/C Compressor, Power Steering Pump, all attaching lines and seals
• Inspect intake Manifold for warping or cracks
• Vacuum lines and Tee connections

Items you should replace at installation

• Thermostat
• Water pump
• Belts
• Hose clamps
• Radiator and heater hoses
• Spark plugs and wires
• Distributor cap & rotor
• Oil, Air and Fuel filters
• PCV Valve

Items you will need at installation

• Oil - Don't forget to put oil in your engine!
  We suggest the use of a good diesel oil and GM EOS or Valvoline Synpower additive for extra break-in protection.
• Antifreeze
• Intake gaskets and silicone
• All other necessary gaskets for installation
  
  

Suggested Break-In Procedures for New Engines

(1) Safety first - check everything you have done, make sure you are ready to start your new engine by reviewing your installation procedures and inspecting all engine and drivetrain components. Set the emergency brake and chock the wheels. Re-check all your engine fluid levels before starting the engine.

(2) Upon cranking your new engine, you may find it necessary to adjust your distributor timing by hand to allow the engine to start. Once the engine is running, you should set the timing with a timing light to the factory specifications and get the rpm's up to 2000 as quickly as safely possible. Note, on late-model computer controlled ignitions this is not necessary.

(3) We suggest a minimum of 20 minutes break-in time at varying speeds. You should keep the RPM range below 3000 and above 2000. It is critical to vary the RPM's to allow proper cam and lifter break-in for flat tappet cam- shafts. Varying the RPM's is also necessary for proper ring sealing and initial break-in of all moving components.

(4) During the first 20 minutes, inspect the engine for any oil, fuel or coolant leaks. Keep close observation on the engine oil pressure and water temperature gauges for any problems.

(5) Once you have completed the 20 minute break-in time and have inspected the engine & drivetrain for leaks, you are ready to drive the vehicle. Do not forget to reset your idle and check your timing.

(6) Driving break-in procedures vary by application, we recommend that for the first 30 to 50 miles that you vary the speed and engine load while keeping close watch on your engine gauges.

(7) After completing the initial break-in drive, you should change the oil and filter. Always inspect the oil filter contents, and the removed oil for any unusual debris.

(8)Once you have driven the recommended 500 miles for final break-in, change the oil and filter again. Your engine should be completely broken-in at this point and ready for normal driving.

(9) You should change the oil and filter every 3000 miles for proper maintenance.
