Loving the names guys!

Yes, I plan on doing that with bumpstops for sure and going through the other things. Basically keep as much stuff that may or may not work or cool stuff. I am curious if the driveshaft slip yoke is the same for 2wds...I will find out and keep it if it is. Squeaky is still at my house so I am going to continue to tear down then once the motor gets out squeaky will be towed down to my buddy's place.

When did an engine swap warrant a name change? Like I can understand if Chris was taking the front end of the envoy and mating it to the hummer for some new h3 look lol but I digress, I like humvoy lol

Really can't call it a Humvoy. The envoy didn't come with a V8 unless it was extended. The donor was an Envoy Denali short wheel base and was a rocket. So, it would be Humnali. Or SqueakyV8, Squeaky5.3 or SqueakyLS. Just glad it went to Chris. So this could happen. Kinda was holding off on selling it to a wrecking yard.

You are on the right track not trying to mess with any other drive line changes. You will have enough tricks to conquer to get you to a first drive with just the engine.

I agree with Kyle , if someone goes in for a heart transplant they don't change their name ... You are making Squeaky sound like the Bruce Jenner of suv's ... And if Chris was doing a full make over ,I'm sure that Squeaky would be one hot Humali ( hummer and Denali , not just a plain Jane envoy)... Chris it's looking great so far keep up the good work ....

I've done enough engine swaps to know that the physical part of installing and bolting up all the parts is the easiest chapter of this story. It's all the nickel-and-dime piece parts and wiring that gets so time consuming that will tell the rest of this tale.

Whatever the name I will say that even though squeaky is becoming a bit frankenhummer it still is all GM. The H3 is a great dual purpose platform. Many jeeps will run a Jeep tub, a GM motor and trans, ford axles, etc. Squeaky is running a motor that was put in by hummer, the axle in the front is from a Uncle of the H3, the blazer...Squeaky is staying Hummer and if it isnt hummer its atleast all the same brand. GM may tick me off but overall their past has done alright. Cant say much about the future, or any car manufacturer for that matter...

Back to the v8 swap...We got the entire truck disassembled and ready to be pulled. We disconnected the entire harness from anything stuck on the body...connectors that go to the PCM, TCM, etc. Its nice to have some help from my buddy it speeds it up a bit, while I am disconnecting motor mounts, hes disconnecting the exhaust, While I did the transmission mounts, he was disconnecting fuel lines, and so forth. Either way we had it all disconnected and were starting to pull the motor out and the motor mount studs were still in the hole while the top of the block is hitting, we could take off the intake manifold to gain us room or disconnect the motor mounts off the block itself but I said we should just get out the angle grinder and cut the studs off so nothing gets hung up. :hack::grind:

It was 1 30 in the morning so we decided to stop there. Hes gone for the weekend so I will probably head back over there monday to finish that. Basically cut the studs then pull the motor, hoist and everything is ready to go.

This weekend I will turn my attention to squeaky thats still at my house, start disconnecting fuel lines, more wiring and basically make it so that when I bring the hummer over there early next week we can get straight to work and start pulling the motor after a few little finishes. Its going slower seeing I am in school full time and working 25-30 hours a week BUT I am glad I can do the swap even if its not during the ideal time.

After the motor is pulled in both I will drop the trans in the H3 (trans and motor are coming out together in the envoy) and we will be swapping parts over to make it work. Later H3 models had an input speed sensor on the trans but 06 and 07 didnt...In other 07 GM models and some even earlier models of the 4l60e did. For my wiring harness I will need to ship it out and have it modified. Once the motor/trans is out of the envoy I can see if it has an input speed sensor if it does were golden. If it does not I may pick up an 08 H3 trans...Basically between the 2 transmissions, my 06 and the 07 trailblazer trans were hoping to piece it together by swapping out the output shaft, the tailhousing, the valve body and pan to make a replica of an 08 H3 trans, which has the transmission neutral safety switch and the input speed sensor. I know the trailblazer trans has the neutral safety switch, I checked last night so were good there. Just need to check on the input speed sensor.

Heres a pic of the motor being ready to get pulled.

Wow what progress your making Chris. It's like every time I read one of your build thread it's like I'm watching an episode of Spikes Extreme Offroad project Squeaky3.

Just did some measurements and it seems as if my space is 12x20 and 3 3 1/2 in deep for pusher fans, wanna add another trans cooler on the 160 stat but it may be way overkill. I may leave it but I do like the fact that if I break a trans cooler rad I can just plug one and run off one.

I want 2 pusher fans, 1 wired to run at a certain temp and the other to be completely manual.

Thanks Torres.

Kyle I heard on multiple occasions that Efans don't work as well in replacement of the mechanical fan.

Btw I like 2006 h3 alpha :) someone who knows hummers knows alphas didn't come out till 08

Yep I'd just get yourself an Alpha Badge for the rear door and call it a day lol. The Efan I tried sucked big time in my Alpha!!!!! almost hit 240F engine temp on the highway due to that inadequate Efan. Stick with the clutch fan for sure and add a puller fan on the front. I still have all my Efan wiring in place and it's going to the PCM still so when I find a fan that'll fit good that's my plan.

That's an interesting looking fan blade on the Envoy. Curious to see if it will fit in the H3. I'm trying an experiment on a LR fan blade as a direct replacement for our Alpha's fan blade. My OEM unit is getting cracks on it, which isn't a good thing so I ordered a 9.90 LR Fan Blade. If it doesn't work I'll just mail it to my brother for his LR so no biggie. Let me know if that Envoy fan blade fits though. Our H3 Alpha fan blades aren't cheap...
