Thanks for clearing that up!!

If You Look Where It Passes The Apex Of Your Lobe Opening....
It Is Below .600 Looks Like Its About .550-.575 On The Graph Which When You Take That X2 It Comes To 1.1 Or 1.15 " I Would Call Comp To Make Sure But 1.4 Is Definitely Not Correct... Unless Of Course Taht Pic You Have Is Not Of Your Cam
Gimme Your Cam Number If It Is Off Teh Shelf... I Can Probably Figure It Out...... If It Is A Custom Grind You Will Have To Call Them

the area you measured seems right.... but for taht big of a base circle would be one small *** grind.... then again ive been awake for about 10 too many hours and may be talking out my *** right now.... do you have soem standards to make sure your caliper is calibrated???
and also if its really cold your caliper will not read correctly
EDIT!!!! screw it just call comp......

Standards from avarage aftermarket cams range anywhere from 1.42-1.48 from what i have seen. It could be more of a broad but im just going off of what I have come into contact with.
