    Default Best camshaft ratio for 2004 chevy silverado 1500

    I was wondering what the best camshaft ratio is for a 2004 chevy silverado 1500 for each the 4.8l & 5.3l i am going to swap my 4.8l(280k and rising) out for a low milege 4.8l or 5.3l( i think a 4.8l because it is going to be turbo'd!!!)

    Well there's a lot that goes into figuring out what cam to get. If this is something your looking at doing your self you should look at getting this book off amazon called turbo charging performance hand book. It's an awesome reference tool cause they show you/tell most everything you need to know. What kind of racing are you building the truck for?

    You mean the best ratio for power and performance, torque for hauling, what are you looking to have as an end product?
