I posted the request this morning for the url for the casting numbers to find out whether the engine in the 540 i'm looking at is nikisil or alusil. Well, after about 20 mins I gave up. I got under the car with a flashlight but couldnt see anything because of underbody plating.

So does anyone have a picture or diagram of exactly where this number is located? I know its suppose to be by the 3rd cylinder but where is this exactly.
