Can someone tell me what the holes are for on the passenger side of the block, on the bottom? Is a 440 block and not sure if they are on all blocks or not???There are 2, one in front and one in the rear. They are about 3/4" in diameter. The one in the rear is next to the oil pan and the bell housing. The one in the front is below the fuel pump. Sorry I do not have any pics. I will try and get some if noone chimes in. Thanks.
