I have my engine top end parts, radiator, water pump, starter, front brakes, exhaust system laying on benches all around my 91 Z

Tell me a bit more about enlarging that drain hole...There is a steel tube (maybe 3/16) at right angle to the rear about 1/2 inch down in that hole. The hole is dead ended down further. The steel tube drains fluids to the rear from that hole and down in front of the fly wheel out just behind the oil pan. I do not want to dump oily fluid onto the flywheel from that hole so prefer using the steel tube. There is no way to enlarge that steel tube without getting inside the bell housing. I will study this further and try to invent a way to more effectively drain that area
