66 Dart GT HT Whatsitgonnabe?

Tried to post the camshaft data earlier but failed. Here it is:

Purple Shaft P4286630: 280 duration, 60 overlap, .474" lift, 106 Rec. Install Center line and Zero Valve Lash Intake Exhaust.

I've tried to find data on the stock cam (1972 360) and this is what I've come up with:
"The 360 cam specs are .410 lift and 252 degrees duration on both intake and exhaust."

From another Dodge forum.
