Craigslist sanity check: 4L80e + 5.7L SBC 350

[gigamanx]

Searching for a donor engine for my Chevy 3100 build because I've realized I have to do too much to keep the stock 4.3L v6 then have to do it all again for a v8 swap later. A craigslist find came up and the guy says it has about 100K miles with a 4L80e 4x4 transmission. Came out of a rusted frame 1/2 ton 1996 pickup. Guy wants $1100 for it all with ECU, wiring harness, alternator, etc.

Biggest issue I see is the 4L80e is 4x4 and I would need to be converted to 2wd. Anything else I'm missing? Seems a few trucks have put this engine and trans combo in. I also noticed it doesn't seem to be TBI which my research tells me is a good thing because it gives me more power enhancement options later.

Engine serial: 10243880
