I'm building up a spare motor and starting with a pretty virgin block. I was going through Purple Frogs old notes on Pintos, and there's a section called "Holes in the stock block to make sure you put something (a plug) into:"
My old race block didn't have plugs in these locations:
Front hole next to #1 journal
Two ports around jack shaft
So which holes are supposed to be plugged?
Also, a bearing came out of one of the oil passages when I disassembled the motor and I didn't notice where it came from.... any ideas?
