Hey guys, about two months I purchased a 05 Silverado 1500 ext cab 4wd with the dreaded 4.8. Was kind of in a bind and needed a vehicle or I would've shopped around and found something with a 5.3. Even though it's currently my daily I would like to slowly build the truck for performance over the winter months. I know it's a 4.8 and it's going to be a bit more of a challenge and more expensive too build than a 5.3. There's just so many places to start with these trucks, I don't even know where too start. If you guys could just give me a boarder line idea that'd be great. I have a pretty decent size budget to play with , but I'll consider every option, because race truck. Thanks in advance
