hello everyone,
im new to the forum and have found some very useful information. i have a 02 silverado with the 5.3 engine and want to start fixing it up but im at about 110K miles, would i be best off getting a new engine or will it be safe to mod?
i also need some help in trying to pick out a lsd because i dont like 1 leg burnouts. any info will be appreciated.

thanks.
