1 Ton Tahoe

Has anyone stuffed a 6.0/6l80/90? 13 3500 Sierra in place of
07 tahoe 5.3/4L60
Maybe just a shifter handle and a HP tuners segment swap?

Photo for context, the low mile hookerbeat 3500 is the potential donor for my sweet Tahoe. Then make the Tahoe gang-bang low on her 24’s ‍

6L90, I'm sure it can and has been done but would also require the cluster from the donor or a new one and lots of programming. Check the Performance Trucks forum.

I want more gears. After much research, I decided it was easier to swap in a manual trans or get an '09+ Tahoe. But, I'd want it to have all factory functions including the TU/TD and proper display on the cluster. It's easier if you aren't concerned about the manual control. It's been years so I don't recall the details, but a friend swapped a 6L80 into his '07 (NNBS) Silverado. No TU/TD. The shifter handle doesn't talk to the trans directly. The problem is how everything goes through the BCM.

Although, if you have the whole Sierra there, you might be able to make it all work. Still, I'd find an '09+ and swap the HD powertrain into it.

I kinda want to make a street demon, wonder if Stand alone paddle shifting is in the wheel house. I mean they wedged 6.6’s in burbans so i suppose it would all bolt together. Im having a hard time not thinking about whipping the tcase off and yeeting the trans and engine into the Tahoe atm. Lol

You wont have to stuff anything since the 6.0L is the same external dimension as a 5.3L. We arent talking SB vs BB here. But GM doesnt make a "Big Block" LS engine by GEN 1 definitions. I can set a 6.0L and 5.3L down in front of you and you wont be able to tell me which is which in 2 seconds. I set a Gen1 BB and SB down in front of you and you will be able to point to the BB in .5 seconds. The Gen1 BB is YUGE! The heads alone are freaking huge when compared to a SB head.

The 6L90 is about 3/4 of an inch longer than the 80 and does not bolt right up to the 1500 chassis, a new crossmember or mount will have to be fabricated, not an insurmountable obstacle. The 1 ton transfer case is different too, the 1500s with the 6-speed have the Magna Power 3023, the gas 2500 SUVs used the MP3024 with 6-pinion planets, the 1-tons are different still and do not have the Auto feature.

Consider selling them both and buying one of the rare 6.2 Tahoes. The 2008s were all RWD, the 2009s could be either. 14-second truck right off the showroom floor.

I do believe this is where the fun beings. More then likely the year gap will require most of then bay harness, Ecm, fuse centre will come with the engine. Fingers crossed they didn’t re invent the GMT 900 BCM in the meantime.I have HP tuners and access to a tech2 so I do have a good swinging advantage. Maybe just plug and plays with the 5.3’s E38 with segment swaps.

Yes the mass is probably 2:3 on trans i was just scoping it out. Sentiment value would be the driver for this my good man.. not to mention I could pull this evolution off for less 10k with tuned suspension, power adder and body all strait. That would come from the proceeds of parting the 1 ton
