Re: [FWDLK] 331 hemi timing questions

[John McCann <jmccann@xxxxxxxxxxxxxx>]

   I'm not sure I would assume the marks are at the ten degree mark, he 
might have made the mark at the proper timing position. The lower mark seems 
to be the advance mark since the light shows the centrifugal advance or 
vacuum advance moving the timing down, try setting the timing on the lower 
mark and see how that works out. Can you see the original marks on the 
damper? One way to check to see if the TDC mark is correct is to pull the 
valve cover over number one cylinder and turn the engine by hand until the 
exhaust valve is closing and the intake valve is opening and rock the engine 
back and forth until it is in the middle of the opening and closing, look at 
the damper to see the location of the marks or make a mark because that is 
top dead center, although it is not on the firing stroke, if you check your 
rotor it should be 180 degrees from number one. Check your timing with the 
vacuum advance hose off and plugged, a golf tee works great. I hope this is 
clear to you, if not email me and I'll try to clarify.
