Rocker Priming: Odd Cam Oil Hole Angle

Just another FWIW note:

We just primed our 340 with a Crane cam, and could not get oil to the rockers despite setting the angles as below (thanks to Tony for this info):
- Turn the motor to 90* before top dead center coming up on #1 compression. The pass. side rockers should get oil.
- Turn the motor to 20* after top dead center just past #6 compression. The drivers side rockers should get oil.

We installed the cam bearings ourselves carefully and shone a light down through the head passages in the block, so we knew we had all that right. And the cam passages were fully drilled through. So after a lot of tries with the crank angles + and - around these prescribed angles, we decided to move the crank to 45-50 degrees before the prescribed points and try at 5 degree increments. At 45 degrees early, BAM-O, oil to the rockers. Same thing on the other side: 45 degrees earlier.

Sooo, with our Crane cam the correct angles for head oiling are:
- Turn the motor to 135* before top dead center coming up on #1 compression. The pass. side rockers should get oil.
- Turn the motor to 25* BEFORE top dead center just past #6 compression. The drivers side rockers should get oil.

Dunno if this is just a Crane thing or other cam makers have this variable. It does not matter in a running engine, just when you want to do pre-oiling checks.
