Dude... don't even complain. lol I have to deal with a carb in sub zero temps. Not fun. Why don't you want a 2.8 or 2.9? they are both great engines. With that budget i wouldn't be expecting a true gem its your first truck its gonna be a piecer and you'll fix it up and learn as you go along. I was lucky to get mine from my dad who kept it pretty well maintained and I have continued that. I'll look in your craigslist thing.
Heres an 84 2.8L with a 5spd $1000. I love my 84 the 2.8L is a fun engine just a pain with the vaccum lines.
