I'm in the middle of upgrading my AX engine. I'm putting in a 78 mm stroker crank to go with the 103mm pistons giving me a 2.6L T4. I have a Scat cam that has about 262* of duration on my 2366 cc engine that I've been running for the past 4 years or so. I finally decided that I would go with a slightly more aggressive cam with 272* duration and bought a Web Cam 86c. the timing card is shown below. Now the question is when I install this cam and check the valve timing at the valve using .050" valve lift, how many degrees of duration should I measure? I was expecting 272* plus or minus a couple. I guess the real engine builders will know what I got. What do you think I should have expected?
