I feel like I'm in the twilight zone....
I think we addressed this already a few pages ago on this thread.
I've always just lined up the timing marks at their closest points with the cam gear dot on the bottom, crank gear dot on top,
then bumped the motor over at the relay using a screwdriver till I felt compression in the #1 hole, lined up the mark on the dampner with zero for TDC, popped in the distributor with the rotor indexed to #1 on the cap, and then started it up and broke in the cam. That's the quick easy driveway cam swap way. The whole process never took me more than an afternoon. I never really remember looking to see if
all these events occured at the same exact point and never really cared if they did or not. Maybe somebody else knows without going into a 6 paragraph dissertation?
CP???
