New guy looking to buy first square body project, need advice.

[wpotter]

I am fairly new to the forum and have decided to find a square body project truck. I have located a 1987 GMC SWB 2WD 350 Auto. It has been sitting under a tree in the guys yard for about ten years. He says it was running but the transmission went out so he parked it. It is all original, paint, interior, engine everything. It has the aluminum wheels and all power options. My concern it that it is fuel injected and has been sitting for a long time. I am not a mechanic for fuel injection but I do know the basics for rebuilding a truck. The plus for me is that it has not had any modifications at all so I have a clean slate. I was going to attach a picture but could not figure out how. My questions are, is this a good year to start being fuel injected, what is a fair price for something like this (he is asking for $800)? Any help would be appreciated. I'll keep you posted if I get it and can figure out how to post pictures. Thanks.
