Bluto.....I don't know about that.... While the both of us favor Mercers I have lots of seat time in (4) t-head Mercer Raceabouts and (3) early Stutz Bearcats. They both have about the same speed and acceleration potential. BUT THE MERCER has it all over the Stutz in all other categories. The Kid below in the 1911 Mercer says "My dad says you have to be nuts to drive a Stutz"
