looking for a good camshaft to my gx270, but we´re restricted to run stock/un-touched carb only jetting allowed, need good midrange power and still can push strong up 7500rpm+++
have been looking at 3 ideffent from dynocams
they are found under gx200/6,5
What is the difference for these 280 CAMs you recommend? Is it just same Lift with a different Duration?
