Numbers i got: lobe lift - .275/.279
valve lift with 1.6rr - .440/.446
approximate lsa - 112
duration - still only have the 249/269(no way to check)




Put the cam back in the block with the crank and timing chain (don't even need a piston for duration.) zero out dial indicator on base of cam, with a degree wheel on the crank rotate till you get 0.006" lobe lift, record degree wheel #, rotate past max lift to 0.006" and record degree #, find the degrees between the first and second recorded numbers and you have advertised duration. Repeat using 0.050" lobe lift if you want the 0.050" duration numbers. If yo have a way to attach the degree wheel to the cam, you could do this without a crank/timing set, but the duration would be in can degrees, so you would need to double it to get crank degrees.
