340 mopar cam question?

Did some detective work. Summit Racing's site,listed these specs:
Summit Racing Part Number: DCC-4452782
Cam Style: Hydraulic flat tappet
Basic Operating RPM Range: Idle-5,800
Intake Duration at 050 inch Lift: 228
Exhaust Duration at 050 inch Lift: 235
Duration at 050 inch Lift: 228 int./235 exh.
Advertised Intake Duration: 268
Advertised Exhaust Duration: 276
Advertised Duration: 268 int./276 exh.
Intake Valve Lift with Factory Rocker Arm Ratio: 0.429 in.
Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.444 in.
Valve Lift with Factory Rocker Arm Ratio: 0.429 int./0.444 exh.
Lobe Separation (degrees): 114.
So the lobe separation is 114.Center line usually refers to the intake opening centerline. Usually aftermarket cams,are 4 degrees advanced .This would put it ,on a 110 intake centerline. Not positive ,on Purple Shafts. Hopefully,some one else chimes in.That way,we both learn perhaps.
