Remember what you stated about timing and porting not having anything to do with getting more speed.
you can't even read and comprehend what's been written. not once did i ever say porting and timing didn't have anything to do with it, porting and timing have to do what
RPM RANGE THE ENGINE PRODUCES IT'S PEAK PERFORMANCE. I'm sorry that you can't grasp that and understand that taking an engine that is ported/timed for torque and under propping it for higher RPM is simply going to cause it to overheat and go lean in the air and die, thereby you'll never get your top end speed because by the time we get half the race finished, you're dead stick and landing...............you also can't stick a pipe on them and expect a significant gain in RPM from doing so, the timing just doesn't allow for it.
