69 Corvette 427 engine on E-Bay

Ask to see a picture of the left rear of the block ( just
above the oil filter mounting area ). If this a true 4-bolt
main block, there will be a three hole pattern with a large
NPT plug in the center location. The left most hole will be
for the oil sending unit location. I'd be concended if you
can't see that location. This can be faked, but most times
is not.
