Thank you all for your help.
I went with the L9H cam to save a few bucks and buy some other goodies to make this engine better and a future candidate to cam up and drop in in a resto-mod if the truck ever takes a dump.
I bought most of the goods on rock auto and Michigan Motorsports and I even splurged a little on needless, but because I can be so extra sometimes, extras like a stud kit the new LS6 Valve springs and the hollow stem valves. Now my wife can drag race the neighbors black escalade on her way to drop off the kids in school.
Ill keep you posted on this second adventure or rebuilding this engine.
Then I will swap my tahoe's rear end on this bad boy and swap the 4wd internals on the Denali's AWD bad boy to make her go go go. My 2002 turd has 3.73 gears, id bet this six speed would fly with that, the heck with the MPG!!!
