....hummm, Ok, Thanks for adding that ... Yeah, in looking at the different cam manufactures web sites I noticed that alot of the 108 lobe sepertion cams were for {as they called it} 'special applications'. 108's that are installed + 4 degrees that make them a 104, etc. etc. etc.... Seemed like a lot of the oval track cams were ground at 108 & it would say "these cams can be used for other purposes also".... But anyway, I've decided to go with a cam that is ground on 110 seperation & split duration.... Thanks again Bill
