Default need help reading cam doctor sheet

http://www.delanofarms.net/camspec.jpg

someone posted this on here before.. 220/220 cam

i know the duration is the .050 which was 219.5 and 220

but where is the LSA of 114 at? The overlap? And the lift? Lift should be .5xx im sure, but i see peak lift on their is .325?

im sure this is stupid, but ive never had to read a cam doctor sheet before so its like french

im getting a cam doctored so i wanted to make sure i can read the sheet when its done lol

.325 is what you multiply your rocker ratio by, like 1.7, so .325x1.7=.553

110 ICL and a 118 ECL dictates a 114 LSA



219/220-.552''/.552''-114/110

you add the intake centerline & the exhaust centerline & then divide that by 2 to get your lobe seperation angle LSA

109.9 + 117.9 = 227.8
227.8 / 2 = 113.9
