Mopar Performance Purple Mechanical Camshaft - P4120653AE Cam Card

The comment about the MP 050 duration numbers being 'calculated' piqued my interest. In the chart that RRR provided, the '528' 440 mech cam was shown as 241 @ 050. I ran that cam many years ago & I measured the duration. I am sure it was mare than 241, more like 244 or 248. Great cam though.
