How many degrees apart is the intake lobe from cylinder 1 to 8 ? I know lobe separation between intake and exhaust is 110 . My crank is to print a rod throw every 90 degrees so from 1 to 8 the crank is 180 and the cam runs half the speed of the crank so cylinder one dose 720 degres rotation to complete one cycle . So I'm thinking there 180 apart ? Anyone have a 3d model they could share ? Thank you all.
