Hi ALL ~!~!
There must a reason why issit a NA engine gotto be high rev ? ? ? since RPM kills motor why issit there is still so many racing engine builder wants to build these kinda engine ? ? ? ? After market Cam tends to have long duration n higher lift which shift the power band to a higher RPM and still many people buy . . . why ? ? ?

:dunno: its like why people don't build a engine with the power band below 8000 RPM so they need not rev so high everytime which in the end made the engine last longer ? ? ? ?
