Hello all, I have a 2008 silverado regular cab with the 5.3L v8. This is fairly comprehensiveu question, but what do you guys think would be the best bank for the buck as far as engine builds. I have $4,000 limit for my motor. I want to build an NA engine and want to stick with the stock block. I was looking at intake, Heads, headers, cam, full exhaust system as the majority, but if you have better ideas let me know. If you can list price as well as estimated gains. I haven't had this truck long and i can't find great research for making a fast street truck. Any help or ideas are appreciated. ALso, I plan on having the car tuned and dynoed so that will go i nmy budget. Thanks for looking.
