Firing order question
so we assume that the pistons BDC 1-2-4-5-3
so i would assume that the cam lobes would too just cause
today playing around with one of my engines i notice the intake lobes 1,2 and 3 hit the peak point where the valve is open in the order 1-3-2 then after a half a rotation(exagerated prolly but to give an idea) of the cam shaft it goes 4-5
its a thinker for me
can anyone elaborate on this, my turbo cam and regular cam did this
