Hello CAFC! I am new to this forum, and this is my first time posting, so please bare with me.
I've been all over the internet and surprisingly this day in age, haven't found any builds of what I am looking to do. I have a 2005 Avalanche 1500 Southern Comfort conversion truck. I got it for a steal because it had a bad transmission. I put a 3.73 planetary 4L65e i got out of a Suburban in it only to find out later that MY truck is factory equipped with 4.10s. Needless to say it has some issues. The transfer case I got with the trans does not match the truck (the truck is the dual-connector, transfer case is the single 8-pin) and I'm not sure the case is 100%. The 5.3 I'm sure is wearing out (although it still has NO issue breaking both tires loose) with 200k miles. Last, but not least let's be honest....its a half ton....
I have an opportunity to get a chassis (truck was wrecked, body wasted but chassis is A1) 2005 (im pretty sure?) Suburban 3/4 ton with the big block 8100/4L80e combo, 4.10 axles, 4WD, etc. Instead of rebuilding mine the way it is which will cost about double what ill get the big block chassis for, is it possible to just unbolt my cab and bolt it on to the suburban chassis? Has anyone had any experience putting a 1/2 ton cab on a 3/4 ton chassis, meaning is there even a difference or all cabs the same? I know that the Burban's/Lanche's share the same chassis, but are they bolt-for-bolt the same? I'm wondering what all is involved with this swap so that I can properly prepare. I am a mechanic in a customs/resto shop with lifts so tooling is not an issue. I am also a former motor controls technician, so electrically I understand re-pins, etc. Any advice/experience/procedure would be GREATLY appreciated. Thanks!
