What's your opinion on the slack in this 318 timing chain?

i was perusing the FSM on an unrelated matter... and guess what? they have the spec listed out right in the print!

with the slack removed and 30 ft/lb of torque on the sprocket bolt there should be no more than 3/16" inch of movement. (15 ft/lb without the heads installed)

I wasn't sure where the measurement was taken, so I had a look at my '67 Dodge Monaco/Polara manual:

So this is different than measuring the slack with a straight edge against the sprockets.

I don't have a cam sprocket handy right now to measure, and I can't find ANYWHERE on the net a spec for the cam sprocket diameter, but assuming the diameter is 6 inches then 3/16 inch is 3.6 degrees. So that's degrees of CAM timing, which would equate to 7 degrees of crank movement. This agrees with at least one youtube video I've seen where the guy is saying the stretch limit is 7 degrees of crank rotation.

According to my manual, this 3/16 inch is the same for the 383/440.
