What all is needed to make the swap? It has no top end. I was going to swap over the headers, my slightly worked 862 heads, 220/224 .581 113+4 cam, accessories, CAI, and buy a TBSS intake, injectors, and tb.
What all mods to the harness are needed other than for the injectors?
Would this be noticeable gain over the same parts in the 5.3?
