Mopar Performance Purple Mechanical Camshaft - P4120653AE Cam Card

Every camshaft I have put in the past 35 yrs have been degreed.
And yes....i got the same results back then and I have two MP 590 cams in use now.....one is a 360 and one in a 408
Thanks. 1 last question if you would.
Where did you find the cams best performance?
