I have a line a free 5.3L, which is good for me since I am going boost anyway, and hurt my nitrous built & forged 347 pretty badly last year.

I can find a definitive answer on if I need to make any wiring changes to my harness or pinning changes to my ECM if I swap my FAST 92mm intake, rails and injectors over from my 347.

I am just trying to figure out if I should pony up the cash and do a forged 383 that is boost friendly with my current block or if I can use this 5.3L easily in a swap.

It is coming out of a '04 1500 if that matters or not.

Should swap right over but will need to be re-tuned for the 5.3l.

Thanks!
