This is the cam I would put in if I ever decided to swap mine out http://www.summitracing.com/parts/LUN-60120/ I've heard great things about the voodoo lobe shape. I'd use these springs http://www.summitracing.com/parts/NAL-12499224/ with these retainers http://www.summitracing.com/parts/CCA-787-16/ so you dont have to do any machining on the heads to make that cam work. I know some poeple have used this kit http://www.summitracing.com/parts/NAL-12480002/ but that will reqire some machining of the spring seats, and IMO that cam's powerband is too high for a truck
