u need to pull the chrome trim off of your taillights, it makes it look better and not so old (look at mine in sig)

also, 350 chevy swaps is the most often used and redneckinist shit there is. Easy, cheap, and their everywhere. No doubt, your swap looks cleaner than most, at least yours still has tpi and not some stupid fuckin carb. but 5k is not going to happen my friend. Not like it is, pull the chrome trim off, sit that bitch on some rims, hell even a set of rallyes with a good set of white letters, and it will pull 4k at a max....blazers/jimmys dont really have a whole lot of market, if it was a s-10/sonoma truck it would probably be easier to sell, put that bitch on mautofied, im sure some redneck will want it
