the 91 has better factory cams. I have heard people call them semi racing cams, not sure about that but they are supposed to make a little more power. 91's are the fastest 240's in stock form. People actually swap cam gears from 91's into their later models for more power. Be careful about buying one with Hicas, Ive heard it wasnt all that great back then
