All front and rear oil galleries are tapped ¼” NPT. They are a straight thread, not a tapered thread. When using a ¼” NPT tapered pipe plug, the diameter of the plug will determine how deep the plug goes into the hole. Sizes from various plug manufacturers will vary a great amount!

The distributor locating bore has been made to fit the “early” type distributor ( .517”). Please check fitment of your distributor before any cleaning or machining is done.
With a vast range of crankshaft, piston and rod combinations available today it is very important to check the clearance of all moving parts – especially crankshaft counterweights and connecting rod to block clearance. All parts must be checked before any type of machining or assembly is attempted.
