Crankgear positioning

^^^ your correct ^^ you should have a smaller dot over the next keyway clockwise. There can be no other option for your dots to match each other.


You got new lifters, good. Good lifters are not flat on the bottom, they are convex (slightly domed) and will rock back and forth on each other slightly. If they are FLAT (no light between 2 lifters base to base) then they are used and should be replaced as they are probably not spinning anymore on the cam and have (started to) wipe the lobe. Measure base to tip of lobe across every one and check for variance, pay attention to INT and EXH as they may have different designed lift. It not uncommon for a used cam to have a few lower lobes but its just worn out, get it reground or pitch it. As for your lower timing gear. Does it have 3 keyways? Simple: the key points right up #1 cylinder (~2:00) at TDC, the "dot" of the cam gear points straight down. So its safe to say that the key and matching mark are about 45 degrees apart. If you got 3 keys, you should have 3 marks ~45 to left from each keyway. Those are your 3 sets of options, -4,0,+4 most likely. Sometimes a dot, a circle and a triangle are used on the crank gear to show the other timing options. you can figure out what is what (8 degree difference) by looking at the distance to the first keyway to the right of the ^ or O mark
