I'll chime in with my 2 cents to help out a new member (like I was not too long ago at all) and say that you're already heading in the right direction by ditching your old 5.7 and going with a 5.3....anywho, after completing my swap I had one regret and that was that I didn't put a cam in when I did the rebuild and to be honest my funds were stretched way too thin and the truck is my daily so I had to get the swap moving double time. If you can't afford a big flashy new cam and valvetrain setup that's totally fine because a used LS6 or LS2 cam will bolt right in with no other mods except the tune to match. Now, I put a LQ9 6.0 into my truck and it already has a decent amount of hp and torque especially with the longtubes and tune so I'm not necessarily missing out on any power but I'd like a little extra to put me over the 400 mark in torque considering I pull a '77 Airstream around and I need a little more on the bottom end especially for hills. If you do nothing else to your engine get a cam and any other LS6 parts your wallet can afford. Also, I almost forgot to mention that I bought an A/C relocation kit from Jeff (Lextech) and I'm extremely happy with the fit and quality of it, (well worth the purchase) so if you have the sanden style compressor, you should also get that kit. And when you pull the engine measure the distances between the flexplate and block on both the 5.3 and 5.7 to make sure you don't need the space/adapter because I didn't on my 6.0 but I heard it might be different on the 5.3

Just an update the swap is done and it is running, i am having a small issue i believe to be wiring related, started it up (FIRST TRY i might add) surprised my self to be honest because i had never done a swap like this before but its throwing me out a p0200 (injector circuit malfunction) and p0300 (random multiple misfire) know i know that p0300 can be caused by p0200 so i am trying to sort that out i have tried swapping parts (coil, plug, plug wire) nothing seems to change it but at random it will switch from number 6 misfiring ALOT to numbers 2 and 8 and then 6 is fine, i have wiggled wires checked grounds(although im still not convinced i didnt miss one) checked grounds at pcm everything i can think off anyone with any advice even if its bad advice i would be grateful
