Engine Break-In Procedure
Use or break-in oil or conventional (non-synthetic) multi-viscosity oil with zinc additive for the first 500 miles of operation. Avoid hard acceleration for sustained periods. Periodically change the engine speed while driving to help seat the rings. While the engine is running, be sure to check oil pressure and coolant temperature, and check for fluid leaks, such as oil, transmission fluid, fuel, and coolant/antifreeze. Also listen for any unusual sounds. Should you hear an unusual sound, shut the engine off, check for the source, and correct it.
Engines with flat tappet cams only - Start the engine and bring it to 2,000 RPM. Get the engine running smoothly. Then vary the engine speed from 1,800-2,200 RPM in a slow acceleration/deceleration cycle for 30 minutes. This is necessary to provide adequate oil splash and lifter rotation to properly mate each lifter to its lobe.
At 500 Miles change the engine oil and filter using conventional (non-synthetic) oil. After 6,000 miles, synthetic oils can be used in your engine. For flat tappet cam engines, continued use of oil with zinc or a zinc additive for the life of your engine is recommended.
Specifications:
I have a 94 GMC SLT edition and the engine is stock 4.3 V6 vortec and wondering would this fit in the engine bay and have it as a daily driver.(I hate this spider injector)
Will it fit a 1973 C3 Corvette L48?
Would this engine fit my 1977 Pontiac Phoenix
Will this engine work in my 1995 k 1500
I’m already set up with a small block 350 with efi sniper . Can the 383 be ran on the same application by simply changing the values
What kind of oil should I use? Where can I get a fuel pump rod and plate for a manual fuel pump?
