Power house options??

[Jodaddy]

Ok guys, my first car was a 80 Firebird love the thing to death, right now it sits on the side of my house with no engine. SO! this tax season im dropin a new power house in it. I wanted to go fuel injection, used that is, out of a wrecked vehicle, but that requires a sh!t ton of work. Im lookin for a relatively cheap engine, already have a turbo 350 tranny 4 it (i have an engine ive been building for it but im still bout 2500$ in the hole and wanna drive this thing one more time before i leave for the army). So im lookin for any suggestions. HELP!
and i know its a chevy but hey man, it was my first car and i still love her!
