Running the lokar XED-5005 dipstick on my 351 with what looks like the ford performance swap oil pan. And when I put 5 quarts in the motor the dipstick is reading way over full. Not sure if anyone has any experience with this dipstick and if I just need to make new full marks or what.
 
See it all the time.

Make your own mark on the dipstick once are certain the appropriate amount of oil has been added.

You may still be half a quart low if you did not account for the oil filter.
