I have the cast iron block lr4 4.8 in an 04 rcsb. I just threw a rod and bent a valve. the block is fine so I am wondering why I couldnt just bore and stroke it? I am going to rebuild it myself and I think it would be cheaper to get a rotating assembly and take it to the machine shop. because even if I do get a 6.0 block I will have to get the machine work done and Im buying aftermarket heads either way I go. what else will be involved in this swap other than the tranny issues? can the block i have just be machined. ????? help

also what crank do you use to stroke the 6.0 out to 408?
