Alright guys I need any help I can get here and knowledge. About to put a new motor in my truck and transmisson For my silverado 1500 it had about 210k on it now. It's got the 5.3 in it now. Can anyone suggest a place where to order new motor? Would you get a remand one or new one? What are some good long tube headers for it and cam ? And is there any more upgrades you can think of that would add more power? May be putting gears in too. I'm not sure yet.
