Cam degreeing help me understand!
Man I can sure use some help. I have spent 3 days trying to figure out why I can't get to a 104 degree int lobe center line. Something is not making sense. In post 155 I last had the crank advanced 4 degrees (with timing gear) and I measured 106 deg.
I purchased a mr gasket 4 degree advance keyway, installed it at the cam sprocket with my timing set dot to dot and now I measure 101 degrees. When I carefully remove the cam sprocket and install the factory keyway I am measuring 111 degrees.
Yes I have re-verified TDC and I am measuring off of the lifter edge. Yes the timing set is dot to dot at TDC. No slack in chain and I am taking my measurements in direction of crank rotation to remove any chance of slack. I am measuring .050 either side of max lobe lift.
