Shortening the sump should make no difference to where the level of oil comes to. It will only make a difference to the amount of oil needed to bring it to the dipstick level after draining the sump however.
Shortening the sump is to give more clearance over the Great British sleeping policeman and his friends.
This will obviously reduce the amount of oil in the "reservoir" but by adding an extension to the side/front of the shortened sump you will regain some of that lost amount.
The dipstick measures the top level of the oil, it's Maximum mark is the top most level that you should fill up to, leaving enough room for the crankshaft and journals to wizz around at 000's of revs without coming into contact with the oil in the sump pan.
Change that level higher and you risk the crankshaft & con-rod bits splashing nicely around in the oil, quickly whipping it up to a nice froth which will do you engine not a lot of good quick style!
Use the standard dipstick just as it was, do not shorten it or remark it, bring the oil level to the top mark, don't go over it. job done.
That is exactly correct. It's a very common misconception that the oil level should change, it doesn't. A dipstick tells you the oil LEVEL not the quantity of oil!
