my 5.3 has 95,000 miles on it...trust me it definately runs strong as hell with a lot of power that surprised most people when they get in the truck...
i was thinking about a heads/cam combo from SLP possibly yeilding 300-400HP...i still want the low end power with very strong midrange as i rarely see the 6,000 that my truck shifts at...

any suggestions would be good...
