Compressed air and particles dislodged by compressed air are potentially harmful. Wear protective goggles when using compressed air

5. Optional Crankcase Modification - 1970-1972 only, using #31-6050 pump body- Plug and Redrill Crankshaft Feed Hole
NOTE - This modification is recommended only if hydraulic lifters are used. Object of modification is to convert 1970-1972 cases to 1973 and later oiling to
give lifters unrestricted oil pressure first. Then it provides main and rod bearings with lower-pressure oil after top end has been supplied.
