    SOI for a GPI SS2 CAM? IVO?

    So I'm looking for a good number for the SOI on this cam. I can figure it out myself but I haven't been able to find when the valve opens (waiting to hear back from GPI) If any one already has done one or has the specs let me know.

    It's 30. So by the math I was taught I should be right around 340 soi at wot? 360-(30/2). Plus another 5 degrees is acceptable.

    General rule of thumb is bigger the cam typically you have less SOI to work with... so being that cam size, 340 be pretty close

    Care to give a little reason why? Was looking at getting one of their cam kits and maybe heads in the future.
