Dominik,
Front sump pans, which came on the vast majority of 460s, and all passenger car 460s, do not have a dip stick hole in them. The dip stick goes through the stock water pump on the top. This is what prevented me from going to a rear sump pan......the rear sump pan dipstick on the side would not clear the headers.
So what I did was baffle the front sump so that
oil would not just rush to the rear of the block under acceleration. This is a very simple mod. to make.
Hope this helps...
John
