The 06 is built and does not have afm, the 07 is a Tahoe with the flex fuel and afm. I would like to place the 06 into the Tahoe. What would this require? Please and thank you. At the time of swap a buddy is going to build the trans. Any recommendations on stage 2 kit or where to purchase from. Thanks

No, you can't do that.

 

The 2006 is a GEN 3 block and the 2007 Tahoe engine is a GEN 4 block.

 

GEN 3's are 24/1x crank trigger, the GEN 4's are 58/4x crank trigger. The knock sensors are in the valley cover on the GEN 3 and the GEN 4's are bolted to the side of the engine block down by the oil pan. The camshaft sensor is by the oil pressure sensor on a GEN 3 and in the front timing cover on the GEN 4. Those are just a few of the major differences in those engines.

as cam said, its not something that can be done reasonably,  however I do believe you can disable the AFM, as many have done so.

Ok I have a monster of a technician. I am sure, this will end in a completed project pictures included. I am just asking for a few tips by those whom have. Thanks.

The LY5, LMG and LC9 are all GEN 4 engines, those all can be swapped into a 2007 Tahoe.

 

The engines have to be from 2007-2009 though because starting in 2010 they added VVT. But if you planned to delete the VVT and put in a normal non VVT timing cover, a newer engine could be used.

You'd be wasting time and money having your monster technician take on such a project. Find a different engine. Gen III to Gen IV is not feasible.

Statement followed by a Question:

 

 I got a 2007 GMC Canyon with a 2.9 5peed in it. It Spun a rod bearing.

From what I am finding online a crank is more expensive than what I am thinking of putting into a 4 cylinder to sell for a profit return, so I am thinking about putting a V8 in it.

 

 Does anybody have any experience on swapping it over to a 5.3 or 6.2? Or would it be easier to just put a old school 350 in it?

Body in 'white'. A shell is what we use to start with building racing vehicles. The basic wiring isn't complicated to reach a legal functionality. Lights, ignition and so on. Most look at a question like this from the perspective of plug and play and what you suggest isn't that. It's the basis for resistance you are receiving. 

 

The question isn't really can it be done. Of course it can. Unless the hot rod spirit has left the male gene. 

 

Your willingness to go "Ole School" points, carbs etc. rewrites your question. Ask it again as if this were  your plan to begin with. You might get more nibbles. It's a much different scenario.  Could even be fun. But....as asked 'can' becomes "good luck'.

Thank you GrumpyBear, I didn't relaise it canceled itself out. I am Backwoods all things I do. Hahaha! So let me ask again.

 

To be a plug and play 5.3 or 6.2 in a 2007 Canyon. What do I need to be on the look out for to change over? Will that 5 speed actually bolt up? Will ecm work that I pull engine out of? Do I need to custom build alot of stuff? I am just getting my feet wet in all of this so all help would be appreciated.

 

I want it to be a sleeper truck then blow somebody's doors like the Old Beetle on Street Outlaws. Hahaha!

5.3 or 6.2 was never available in a Canyon. Ergo as Cameron said plug and play is a non starter. 

 

My comment was based on the idea you were willing to go "Ole school" and use a Gen 1 SBC pre computer set up. In which case there is fabrication of mounts and a wiring harness from scratch. 

 

Guys drop LS1's in old iron but it requires a stand alone ECU/PCM and again a some custom wiring. Would also require an early non TCM type transmission. TH350/400 or manual conversion. Lots of fab work. 

 

Basic? You gut the truck and start fresh sheet of paper. This is not newby territory. Full on custom wiring bumper to bumper. Fab a dash. Move a firewall, fab the tunnel maybe. Tubs. Frame fabrication. A skilled fabricator would have second thoughts. 

 

Every major city has SOMEONE that is up for such a job but bring wheel borrows full of cash. Look in Atlanta. Best I got.

GM put a 5.3 in those midsized trucks around 2009. Probably only with a 4 speed auto. I only saw one on the lot new. Never saw one used. Find a salvage yard they probably could locate a wreck one. Or go to a GM dealer for parts.

Over on the Performance Trucks forum fellas over there say the aftermarket makes conversion harnesses to put a Gen III motor into your Tahoe with the Gen IV motor.

 

If you wanted to drop in a Gen IV 6.2, you could relatively easily pin your original computer for the VVT and then update the tune for it.

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      I have never seen GM instructions for the other trucks as per the HD with the 6 speed or the half tons but had got the impression that the HD trucks with the 6 speed were not having the same problem that the 10 speed and pan presented. Also video that I have seen of the HD 10 speed with the gas engine starting in 2024 model year showed that it was a real struggle to even make it work when pulling down hard on the exhaust after undoing the exhaust hanger bracket on the side of the transmission as after all there is little room for the pipe to even go down behind the Y joint as it soon would hit a frame cross member. Also that they had tried just like I did with the gasket off and no way was that pan coming out any way they tried to manipulate the pan. From that as well as the local transmission shop talking about the pain in the rear issue, I was not expecting my pan to come out because GM shows it was not even intended to come out without dealing with the exhaust piping.    It would be nice to claim, here's what you do and its easy to remove the pan guaranteed on any HD truck with the gas 10 speed but dollars to donuts the next guy trying what I did would not have the same luck as the exhaust was just manufactured slightly different and be pissed off at my claim that the pan comes out with no issue. Its more of a try and see if your particular truck might work like mine did .... or not !.

      Sorry I didn't see this until now, but it works on both the 6 speed and 10 speeds, as well as all the half tons too.

      Engine vibration after motor mount replacement.

      By 1998sleaze · Posted

      Hello, I have a 2018 GMC Sierra 1500 that I recently changed both motor mounts on due to the driver's side being blown out. After replacement I seem to have a steady vibration that I can feel in the pedals and the back of the seat. At this point I'm convinced that the aftermarket "Anchor" branded mounts I used are not performing as well as OE, the only real reason I ended up using the mounts in question was because my local dealers were out a few months to get a Driver's side mount. I've tried "Neutralizing" the mounts according to the motor mount TSB published for these truck to no avail. My trans mount is also in great shape and seems to be absorbing vibrations swimmingly. As far as I can tell there is no issues idling, my idle RPM is steady and I've recently put GM plugs and wires on, however, I have not cleaned the throttle body or intake valves. Any one else have a similar experience with aftermarket mounts? Patience certainly is a virtue that I wish I exercised here. Thank you!

      I still saw people out for runs, on their bikes/motorcylces, jeeps with the doors off driving around here the past 2 days. I guess we are just used to it here haha.   Tasted like a bonfire the last 2 days.

      The TCM has to be flashed before it can drive.   If you installed it the way it is, it has the OS (operating system/program) from the 2010 truck you got it from. That will not match with the VIN/OS pair that your 2013 truck has.   You can do the full install. Then tow it to a dealership and they can flash the trucks PCM/TCM with the latest program for your VIN.
