Cam choice for new GM 260hp crate motor
I think I'm going to buy a GM Goodwrench 260 hp crate motor instead of the 290 hp GM Performance crate motor for my '76 El Camino SS (and save almost $400). I plan on buying and installing a new streetable cam proir to installation, to go along with my existing Weiand Action+ manifold, Edelbrock Performer 600 cfm carb and Hedman Elite hedders. I've been told that a good cam will really wake up this motor. What type of cam should I install in my daily driver 2 ton Elky? Is the warranty void if I install a new cam in the crate motor?
