If going with a stock cam, go with OEM.

Richardman thanks for input but LM7 chevy cam lacks in lift as far as I can tell. Brandy new Melling cam is $150 at Summit. Used cam and/or lifters make me quiver. Just got my parts list for AFM delete together and I'm headed into town on horseback to the blacksmith shop to place my order.

LM7 cam is smaller and makes less power. The early (2007-09) Gen IV 5.3s have the same grind as the Gen III L33.
