Regarding the split ration rockers, they said yes, when using the AFR heads, the EXH ratio inefficiency is very good, so slowing down the rocker with the 1.5 will actually boost the TQ in stead of using a 1.6's on the EXH. This was exactly my thought, on accident of course, but I knew the AFR EXH flow efficiency we @ 85% based on my flow charts, so there was no need to leave it open as long, and by using a .612" lift on the Intake, this helps the top end but sacrifices some low end TQ. Since I have 210cc heads, I did not want to kill anymore of my HP than necessary.
This does not affect the timing events, only the speed of the open and close of the valve and the lift. So, I'll be using 1.52-Exh & 1.6-Intake on the new cam
Cam specs are; 228/234 @ .050 284/289 @ .006 114 CL .3825 lobe x 1.60 = .612" .3825 lobe x 1.52 = .581" Overlap at .050 = 3* Overlap at .006 = 58.50*
So of the stuff came below and the cam will be ground this week and be back in my grimy hands next week.
Christmas came early for you. Care packages from Summit/Jegs are always fun to get!
