Timing the cam - what about the intermediate shaft to crankshaft?

[jdbubb at verizon.net (Dan Bubb)]

The absolute position of the auxilary shaft isn't important at all. As long 
as the distributor rotor is centered on the #1 wire in the distributor cap 
when the engine is at TDC and the cam timing mark is lined up per the 
Bentley with the top of the inner timing cover. ( this is an 8V right??)

Turning the engine by hand is sort of an on-off affair. If you're pushing 
into a compression stroke for one of the pistons it'll be hard to turn, if 
you push through that quickly it'll tend to pop over center, otherwise it 
turns pretty easily.
If you have doubts you can try two things. Pull all the plugs in which case 
it should turn pretty easily at all times although there will be slight 
variation in force depending on the piston position. Or you can do a 
compression check.
