Oil drainback: Do all the small and big blocks drain the oil back through the lifter valley?
This is a topic that I never thought of. Oil drainback. Look at the picture of the deck of an LA series:
Here is a 440 block.
All I can see in both blocks are coolant holes and head bolt holes. Does all the oil that makes it to the rocker gear drain back through the lifter valley?
