ol'55, I don't know if they made different sizes of oil pans for the 235. I would make sure about that. If the pan you have is the same size I'd check the dipstick to see if it's the same length. Some thing is off, the pan size or dipstick length. Like someone said, it should show on the stick with 5 quarts in the pan. Some one here will be able to give you the length your stick should be. And also probably the out side deminsons of what your oil pan should be. Good luck. Mike
