Thanks Mike, so let's plug in my numbers.
Cam 270 S lobe lift is same for both int and ex. 0.313" X 1.5 rocker ratio = 0.4695" which is valve lift. How do we apply/verify this number against the spring specs?
I printed off 2 different tech sheets from comp on the 901's. Slightly differing specs....go figure lol(see pic).
So the valve lift of 0.4695, which number does this get "verified" with?
Thanks guys!
