402 block holes above oil filter
Just had engine rebuilt. Took a quick look at it and found three holes above oil filter in block. Big one for oil sensor? other two?

Re: 402 block holes above oil filter
Big one I believe is oil sensor. One toward front could be oil line (mechanical gauge) the last could be the clutch ball pivot.

Re: 402 block holes above oil filter
the large one and one small one go into the oil galley. can run a oil pressure sender or gauge off one. the other small one is not tapped into the block. can be used for clutch z bar as said
