First off, being a former TV member, YES I did use the search feature. I saw where people were talking about it but not doing it. Has it been done on a 4x4? I have a blown 4.2 and I am looking at all of my options. Thanks.
And, I sure the overall engine transmission length will be different, changing the position of the transfer case, requiring different driveshafts.djthumper said:And changing the rear end to the 8.5

You guys are more then welcome to meet down here, I am sure I can find a place for us to work.smitty5150 said:I am about as far away as you can get from taking that offer, meet half way?![]()
ScarabEpic22 said:You have an 02, 02-04 I6s should be the easiest to swap a V8 into. Easy to get a GM PCM in there, GM already did it for us! Run a 1MB LS1B PCM out of any 03-07 fullsize truck, find an 03-04 5.3L TrailBlazer pedal assembly and throttle body, full flash an extended TrailBlazer OS into the PCM, retune it for your setup and call it a day. The electronics ARENT that hard for 02-04 (maybe 05s), its above that when you get into the CAN based stuff where it gets tricky. You *might* have to have a dealer reflash your BCM with the firmware of a LWB TrailBlazer, but I cant verify that.
The radiators are different between the I6 and V8s, Id get a V8 one if you want to do the swap. Easiest way to do this would be to find an 03-04 5.3L LWB TrailBlazer/Voy that has been rear-ended and steal all the needed parts from it. Doesnt mean you have to use the 5.3 though, a nice cammed LS1/2/3 would sit nicely in there too.
Ive put this out there before and will again, if anyone in the NW wants to attempt a V8 swap in a truck originally with an 02-04 (05 maybe) I6 I will donate a few hours of time and an EFILive license so you can get it running (VIN change, VATS, engine displacement changes, etc).

Riddlebox0333 said:I'm from that area, my brother lives in La Conner and I go there a couple times a year to fish. An LS would be great, but then EVERYTHING in the chain would have to be replaced to handle the HP. Upgrade the tranny, then the transfer case, drive lines, then do a straight axle swap with maybe some Dana 60's front and rear with lockers, then a full roll cage.But then I could roast 44" tires down the 1/4 mile

Jkust said:The 5.3 gives you a little extra oomph on the low end on up but if I'm you and going through the effort, I would look at an LS1. There are lots of 6.0/tranny packages on Ebay generally and suprisingly cheap with low miles.

gmcman said:Bore the 4.2, get a custom exhaust manifold and add a turbo. Build up the trans, swap the rear and you get to keep most of the plumbing.
smitty5150 said:I am considering it. I have to think about the other upgrades involved also. With a mildly built 5.3, I can reuse my trans with a rebuild, shift kit, etc. But it really isn't hard to find a complete ls1 drivetrain from a camaro or firebird.
smitty5150 said:I also would not mind running a turboed 4.2. Something I haven't looked into, though. Not sure how much more difficult that would be, though the benefit of keeping a lot of parts is slightly appealing.
ScarabEpic22 said::wootwoot: I really want to see someone step up to the plate and do this, Id be there but now that I have the SS and dont have a job, not happening. Ill help build it though!
gmcman said:Oh, it would be most appealing....
Pull out the washer fluid reservoir and you could carry a baby kangaroo in there, all kinds of room for extra plumbing if needed.
Was it not a pita with the 02 ECM on retuning for forced induction...something like not allowing over 1 bar? Tell me it's doable and I may lose sleep.
If mine ever goes belly up that's what i'm going to try to do. Trans will be worked once it goes so the rear will be the next upgrade. Mr OP....not trying to derail your thread, but someone said .........t u r b o....Wait, that was me.

ScarabEpic22 said:LS1 = 5.7L...
LS2 = 6.0L, like it but want more cubes for the SS. Make my 02 pretty fun though, but it'll have to get sold to pay for the built LS3 down the road.
smitty5150 said:When I pull the trigger, rear will be swapped for an ss rear and I will convert to 2wd. I'm not looking to make a complete monster out of this, just a beefy dd that can handle the occasional track day. That, and the satisfaction of being the first known to do a swap without completely gutting and rewiring everything. I know there is the mentality that bigger is better, but I see no reason why a cammed 5.3 with a small supercharger(and a few bolt ons) wouldnt be sufficient. Add that to a slightly built 4l60 or 4l70 and I should be set. Since my drivetrain is 100% operational, I will be able to part it out to help offset costs.

If you guys can figure out what needs to be changed on the V8 PCMs to run in a I6 chassis, I'd be happy to program them for my standard price of $99.
gmcman said:This is approaching the limit of my paygrade...but I believe the 02 ECM is different.
ScarabEpic22 said:Have all the parts, just need wiring and connectors (the expensive part lol).![]()
gmcman said:You can use the wiring and connectors on mine....
Tell ya.....when daycare is done....lookout.
ScarabEpic22 said:Good idea, you could leave it 4WD if you wanted as the only part seeing the power on a daily basis would be the xfer case and they're pretty strong already. Shouldnt have to mess with the front driveshaft either, rear will have to be swapped/modified to work with the 9.5" rear though.
Heck even start with a cammed 5.3 setup for N/A then down the road swap cams and stick a Maggie on it. V8 cams are cheap ($400), but might have to do rockers/pushrods too (probably closer to $800-1000 for it all).
ScarabEpic22 said:Need just the PCM connectors from an 06-07 I6, and ONLY those years (or 04-07 I4/I5 out a Colorado). Already have a P10 to test it on, and if my trucks in Montana with my brother Ill persuade Craig (FlyingFischer) to let me use his truck.
smitty5150 said:5 min on EBay finds this in my area:
[EBAY]200689525518[/EBAY]
[EBAY]200701526400[/EBAY]
They include the PCM, engine harness, pedal assy, all accessories, and MAF. THIS makes me wish I was ready to buy now.
limequat said:I recently picked a PCM out of a saturn of some sort that appears to have 2 of the 3 connectors on a 2006 PCM. Might be a cheap source. I got the PCM and connectors for like $20.
Edit: just confirmed. The saturn connectors fit the 2006 PCM.
ScarabEpic22 said:Awesome news, eBay? I need all 3 connectors and all wires intact, if I need to move a few thats not a big deal, but Id like the majority of the wiring there (I can hope right?!). Saturn Ion Redline perhaps, they run a P12 too. Also I should be looking at LLY Duramaxes and E40 cars/trucks too.
