Help Pricing Parts Removed From My 9,317 Mile Nova

I have question and I hope you folks can help me (and I hope this is the right spot to ask it). Anway, in a few weeks I’m going to get to work on my ’69 Nova. The plan is to turn it into a LS7 (old style 454 fat block), Turbo-Hydro, Dana 60 Day 2 sort of car. Right now, it has a stone stock 9,317 original mile 307, Powerglide, 10 bolt in it. I certainly don’t want or need the mouse motor, the ‘glide or the 10 bolt (along with plenty of other pieces). What’s a fair asking price for the engine, trans, converter, driveshaft and rear end?

Thanks in advance.
