On those camshafts on the level 3 it says on one brand that it is a rough idle, and on the other one it says very very rough idle. what does it mean by rough idle and can that be fixed by custom tuning.
also on the crower brand it doesnt say it needs lower gears but on the crane brand it says lower gears required.
and what can those springs do
and as far as the cylinder heads go. it talks about the 5.4 in the description but it only talks about the 4.6 in the applications.
