318 cam shaft selection/upgrade for stock engine

Gotcha and thanks very much; I was looking for something like that. Where is that from? The source document may explain how they measure .050" lift.

I am willing to bet a bunch that the MP .050" numbers are a .050" valve lift, which would be at .033" tappet lift. Other similar cams are listed below for Adv duration/.050" tappet lift duration/difference:
Crane H-248-2 248/192/56* (softer ramps)
Lunati Voodoo 253/208/45* (fast ramps)
Comp XE 256/212/44* (fast ramps)
Racer Brown EH-4 250/200/50* ('kinda' fast ramps)

Regardless, the MP is heading in the right direction for a cam for the vacuum the OP wants...'cept for the 110 LSA.
