Thanks! I'm slightly favoring a 6.0 over a 5.3 anyway. In the reading I've done on other forums, some people have said that the Gen 4 engines all had the AFM cams and lifters, even if it wasn't used in the vehicle it was installed in. At least that was how I interpreted what I read . I'm hoping it wasn't entirely true, since I would like to be able to extend the pool of used engines I can pick from. It's getting harder to find lower mileage engines from 07 and earlier at good prices. This truck is pretty much a blank canvas when it comes to engine, transmission, interior, and a lot of other choices. I'm trying to keep the cost down while moving it ahead. Guess I need to figure out how to include a link to my "build" so people will know what I'm up to!
