Why is it...

When Mopar guys are talking about camshafts, they seem to refer to lift. For example, "I have a .590 cam in my....".

In my past experience with Brand X, camshafts are referred to by their duration, either advertised or at .050. It seems duration is more relevant when discussing cams because it tells you how streetable the cam is, and if it'll require stall/headers/gear.

So were the old Purple cams advertised by their lift? I'm just curious as to where this started.

Probably cause there's is and especially way back, fewer performance parts for mopar so a lot ran purple cams, so your talking about handful of cams so everyone knew the specs, some reason people latched to the lift probably cause it's sounds like a bigger number and probably cause brand x guys didn't :)

Few fully understand the specs anyways for a lot could rated them by there lumpiness and would find that more useful lol
