When a Cam comp. states a cams Lobe Seperation Angle as in 108 , 110 , or 112, they are indeed referencing a Lobe seperation in CAM degrees
IN D50,s case he states Two numbers add those up! They will equal 216 CRANK degrees. So is his cam a 216 LSA, because in Crank degrees those lobes are indeed 216* apart
Or 108* apart in Cam degrees. The crank turns twice for every one revolution of the cam.
Lobe seperation angle is Cam degrees.
Installed Intake centerline is Crank degrees.
The Math doesnt lie, it either is or isnt.
Look at the graph I just posted... does it look like the lobes are greater than 180* apart
EDIT The cam LSA is indeed measured on the cam itself but in the above you add the 2 together then divide by 2 to find the average(108 in this case)
Yep, Indeed Everyone who listed thier LSA whether it was 107 to 117 was in Cam degreees.
You could list it in Crank degrees too, but nobody did. If they did the numbers would be 214 to 234
