Jiggle Pin on the 427
Fascinating thread on the jiggle pin used in the 427.

EDIT -- From that thread: This valve would have been placed at the front of the top oil passage, behind the timing cover, the purpose apparently to quickly "burp" air out of the gallerys to speed oil flow into the lifters upon cold startups.
