Well lets all hope its not too terrible and thank you can007. I understand the battle I'm going to face, but I really love this car and i'd rather deal with all this crap than make my dad pay and extra 6000$ on insurance and 4000$ on the h3 for me to drive around a clunker.

Hey derian good on ya for taking that girl out for a good time. That's what these trucks are for, to be enjoyed. Looks like you enjoyed the hell out of it this time.
If you were closer I would offer my hand with any help you needed. It seems like you have a your head on straight have done your research and know some options ahead of you. Some of the guys are just throwing out what ifs and maybes and some of those are from hard earned experiences of their own. If you do pull off an engine swap I would love to see that and I'm sure the nay-sayers would too. Or if you just clean up the truck you have now and drive on. Literally.

So you know the 07 is the easiest of all the years to make the 5.3l swap. It has the largest capacity (memory) of all the PCM's. No TCM. Tuning won't be hard. Yes you want to keep the 4:56 gears. The tranny bell housing will need to be bigger. James for the Colorado forums can help you with the wiring harness. He is in an electrical engineer, and has a ton of experience with that. As well as the tune if you want. There are other things mentioned here that will need to be done.

You are very right. The Colorado guys have done it. It can be done. It will take time. And money. But is by no means impossible. Good luck and if you go the 5.3l take lots of pics!

You might be the first to help some of these guys change their minds on how "impossible" or difficult it is.

Thanks alot man! Do you have any contact information for James? I contacted current performance for their wiring harnesses seeing if they had anything to help me with my 3. In about an hour or 2 i'll know whats going on and i'll post it right up. Thanks again to everyone who's positivity is giving me some hope on really making this turn out well!

So do I keep an 07Pcm? I was going to go straight to PCM of NC and ask them for an alpha PCM.

Did you take the intake off? How did the throttle body look? Any signs of moisture in the intake tube or on the throttle body? Did water actually make it into the air box. Judging by the water level, it looks like it could've but it may not have gotten in till after you shut the truck off. And was water over the top of the valve cover? The easiest way in would probably be through the coil packs up there. I think your motor will be ok. It's the electronics that need the love. I think you can flush the diffs and t-case and fill em in back up. Flush the tranny too. I think you'll get it started and running again. I would disconnect all the wiring connections I could and hit them with an air hose. Force the water out vs letting it air dry.

no - the I-5, you swap PCMs with PCM of NC; on the 5.3s, it's a different computer (much, much better computer) that allows reprogramming with HP Tuner software... meaning, you don't swap computers, just the software inside.

I'm pretty sure my PCM is done for, so I do order the alpha's PCM? Your wording kind of threw me off I just need clarification.

I have no idea whether or not the computer is plug and play to swap from the Alpha - I'd suspect no, but one of the reasons I love GM is they tend to use the same things if they across platforms and packages. If the computer doesn't plug and play (meaning, simply pull the old one out and put the new one in) - then you're stuck swapping wiring harnesses.

The absolute cheapest way to get a V8 will be to buy a wrecked Alpha and swap all the necessary parts - which, warning, could be everything. When I do a duramax swap in mine, I'm buying the wrecked vehicle and doing the swap.... I've learned the hard way (as has my wallet) that trying to piece it together from multiple sources is a pain.

He has a guy right down the road that does 5.3 swaps for a living, and he has all his own harnesses, computer, and everything. Everything will be done for under 8-10g. After he checks the motor my hummer is going straight to a detailing shop to take care of the interior!

Locked up motor? Did you pull the plugs and fog the cylinders first? Nothing about a water crossing should lock a motor unless there's still water in it. Well, after only two days anyway.
