I agree with you on the port timing has alot to do with the power gain on these long rod motors,or even a stroker motor,no arguments here,everyone,or engine builder has his own beliefs,on what or will make more preformance,but if you talk to the guys over at oniel bros they will agree if your running a 4wd car like a losi,the 30.5 is better for the torque factor then the long rod.like we were saying everyone has there own opions,no offense taken.
