    From what I understand the 4.8, 5.3, 5.7 and 6.0 interchange parts as needed.

    The 5.7 Vortec will not interchange parts with a 5.3, the LS1 will however, if thats what u meant. I think most parts can be swapped out for each other, there will be some come along with better responses than I can give.

    yeah, 5.7L LS1. I only figured someone would figure that one out since this is the LS1Truck website.

    Yeah I was just making sure, sorry man, I guess I am just use to people being completely idiots on Chevy Truck World&#33; Thats why I like it better over here, most people actually have helpful and correct responses and arent just pulling info out of their butts.

    I guess that would be like someone selling F-body parts on a Corvette site. I&#39;ve seen it. Guys on the vette site get touchy about doing that.
