I think he believes me that the 400 on the lazy side will out last the smaller wound up power plant. He sees the difference in out dirt bikes, my lazy 4 stroke vs the screaming 2 stroke he rides. I remember how the old chevy 11 handled. Brakes were terrible. When you made a hard stop. the body would pitch forward and the rr wheels locked up. Of course it was meant to be an around town commuter giving 16 mpg.
