i agree there is a speck of a mark in the correct place but i couldn't see it when i put it together. they put the big mark matching the cam gear on the keyway. if i built motors offen i might have thought hey the mark isn't always on the keyway. but who am i to question they way they make gears. heck there is 3 keyways. i know what they are for but i couldn't tell you where they should put the correct mark. all i wanted to do was make it dot to dot.
this cam pistons and rockers were all happy together before. so i didn't worry about degreeing it. i bal. the bottom end and put on a new timming set, BM flex plate,new harm. bal. and thought i was good to go. as you can see there isn't much left of my KB107.
