Newbie here
I am putting an LM7 in a 2012 Colorado.
Complete rebuild on engine standard bore standard rod bearings standard mains. I’m running flat top pistons 862 heads and considering San intake upgrade. Looking to make 400 whp. I’m not sure what cam I want to go with?! I’m thinking a 223/227 600 600 lift on a 113. This is based on some info from Bart at Hi Tech Motorsports video on YouTube. Like I said newbie LOL. I’m not sure if I’ll need to change the valve springs and or pushrods either. Sorry if this post is in the wrong place but any help would be great.

Big fan of the LS engineering though.
