Hey guys whats up im new to the site. Ive got a few questions for you.
I have a 2008 silverado ext cab 2wd with the 5.3 and 3.73's yadda yadda yadda. I want to cam it and put heads on it heres my question. Do i have to get rid of the DOD, (thats fine with me) I was looking at getting 6.0L heads, and the TR220/220-114 cam. Will this be a good combination? Should i notice a pretty good difference? Also are the 6.0L heads worth it? I can also get a set of LS7 heads if they will work. My mods as of now are just a volant intake and a 3.5" catback. Thanks and it seems like a great site im gonna stick around.
