Thanks Paul,

I guess that may be why the Ex Port is lower in the cylinder than the other long rod motors !! The part I don't understand is the piston speed in a long rod will be higher than in a short rod turning the same RPM !!
You would think they would work out the torque and HP curve to come in @ a lower RPM because of the excess Piston speed..
Anyway I'm going OLD SCHOOL now where did I put them 11X7
