Here is a tool we needed in the shop. When Chevy put straight 6 194-230-250 in ChevyII Nova's. The block was drilled in a very specific location to match the front sump oil pan. We made a drill jig to aid in this feat. The drilled hole is on a angle in 2 planes. Very hard to do with a hand drill. This jig takes all the guess out. X marks the spot drilled. Available on the site as a rental.
