[TR] valve timing update

[Tony Drews]

Normally you would measure when the tappet has moved the pushrod 
upwards 0.050" (or the amount of movement the cam builder 
specifies).  I have no idea of the cam timing of the stock cam, but 
the cam card normally gives an opening degree measurement, a 
centerline of the lobe measurement and a closing degree 
measurement.  The opening and closing measurements are at a certain 
amount of lift from fully closed (fully downward).  I turn the cam to 
where it is opened the correct amount, set the crankshaft to the 
"opening" degree measurement and figure out the closest alignment of 
chain and cam sprocket for that, and bolt the sprocket on the 
cam..  I then rotate the crank two turns to get the camshaft back in 
that position to verify that I got it right the first time.  Then I 
check the closing event to see if it's close to what the cam card 
says.  If it's off by more than a few degrees, I adjust the opening 
event to split the difference.  That gets the centerline of the lobe 
where you want it.

Hopefully someone will pipe up with the settings for your cam and we 
can get you going.

Cheers, Tony Drews
