Absolutely!! Go as big and nasty as you want! Your grandson is a smart young man. I just got talked down off of the 440 6 pack 5 speed ledge. Mine will be a driver, so I can't go too radical and still keep it dependable for a 2 hr roundtrip trek to the office. There would be no space to work. The 340 will have to do.
