How would retarding this cam affect ET's?
My current cam is a UD soild roller with 263/268 @ .050,, .417 lobe lift with 1.65 rockers. The LS is 108,ground 6 degrees advanced to 102 ICL.It degreed in at 101 3/4 ICL.My timing chain has advance and retard positions which I assume are 4 degrees either way.So if I retard it 4 degrees ,that would be 105 3/4 ICL.I wouldnt do the change until I get a baseline with the new 4.11 gears.
