Would I get my money back if I sold this?

A couple weeks ago I bought my '79 C20 LWB for $550. The body is straight and rust free, but that's about it's only good feature. I bought it just as a beater for hauling parts, but now I want to restore it.

Here's what I want to do:
Paint it myself ~ $400
Wheels and tires ~ $1000
Interior replacements ~ $800
5.3L/overdrive tranny swap ~ $2000

Roughly $4750 total. Probably closer to $4500. Do you think I could get that much for it if I sold it? It would basically look and run like a new truck...but I know 2wd, 3/4 ton, and LWB aren't "the rage" right now. I have no plans to sell it after doing all that work, but I change my mind drastically overnight...
