5.3 to ls1 Ok guys, I am going to be swapping out the 5.3 out of a 1999 1500 Siverado for a ls1 and wanted to know if there is anything that I will need to complete the swap. The injectors and map sensors are different if I'm not mistaken, but if I just swap out the longblocks and reuse all the truck stuff (sensors, accessories, harness, ECM etc...), it should be a straight bolt on shouldn't it? I would appreciate any help or advice anyone can give me.
