Hi guys, found this site about 6 months ago and have been addicted to LS engines since. I have a 1999 chevy silverado ECSB 4x4 4.8L. I am hopefully going to buy a used sts kit in a couple weeks and start collecting everything else i need for it. Definitely planning it out so i wont have problems in the future. Starting to rant so thanks for all the great info on the site.
