I've looked at a few M211s and have thought the same thing. With the

3400 rpm is acheived at about 53-55 mph and that corresponds to what the
other guys on this list have experienced. Running a well built small

however I think running a 454 at those speeds and higher might result in
much shorter engine life with stock parts. I believe the stock 302 ci

has been quite a bit of discussion on engine swaps into the 211 before.
Good luck and let us know what happens.
