After assembling the motor check the oil level in the tank. Start the motor and allow it to build pressure to verify that oil is circulating. Shut off the
motor and check the oil level again.

CAM SWAP INSTRUCTIONS (Includes Pinion Gear Removal)
Before you can swap the cams, you will need to remove the pushrods and lifters. Next, remove the cam cover and all of the screws in the oil pump
cover. Use two flat blade screwdrivers in the pry points on the plate to remove it. Seen picture 36, below.

Start by inserting a wire-tie into the gears to immobilize them. See picture 37, below left. Remove the bolt in the pinion gear (picture 37a, below
right)
and then insert two 5⁄16-18 x 3⁄8" set screws into the pinion shaft (see diagram 5, below) be sure the second set screw is flush with the end of
the shaft when it is tightened against the first set screw. Follow them with a 1⁄2-20 set screw or bolt and pull the gear off. It is important to use the
small set screws to prevent damaging the shaft when pressure is applied don’t skip this step.
