05 Silverado parts

[57taskforce]

I’ve just acquired an 05 regular cab long bed Silverado 3500. I payed 1000 for it in running driving condition. 187xxx Miles. I initially got it to do an 8.1/Allison swap in my 57 3100 4x4. My question is (and this is in no way a for sale ad) if I robbed the engine trans and associated swap parts could there be enough money left in the rest of the truck to come close to breaking even or at least get half back? I haven’t parted a 99-06 before thus I don’t really know the market. I’m more into the 72 down trucks and parts. I’m trying to decide whether to part it out or just sell it off complete and make a few dollars on it. Ive got an 8.1 in my wife’s suburban and I love the torque.
Thanks
