between these 2cams in question i mention the 590 because i can get it cheaper than the UD. for the cost of the UD i can get cam and tappets! now i dont know if the newer ones are any good..? do the newer MP cams go flat more so that old ones? i think i read somewhere they changed vendors.. any which way i slice it, ive always liked and wanted to run the 590. hopefully my car will weigh 3400lbs at the line.
