1987 gmc needs an engine. help please?

[jesdude7789]

This past weekend was my brother's wedding in Austin and my truck has been having some issue for a while now and I drove it over there on Friday night. It has had a knock but I had no choice but to take it. Well..... I let my brother borrow it, the engine seized, now my truck is dead and I had to leave it there and luckily I got a ride back to Houston with my dad.

I have been looking on craigslist but I haven't found anything that will work yet. I'm hoping to find any of the 88-95 engines for sale and freshly pulled out or still in the truck running so I can hear it in person. I say 88 and up because I want to get the serpentine style belt setup in the process because my 87 engine is TBI but it has four v-belts which have always been a pain in one way or another when servicing it. Anybody on here in the Houston area have one of those? Any company that y'all recommend to get one from or had experience with?

I can't afford to buy a crate engine for this because it's about $1800. My engine had about 135,000 miles on it and I want to get something with similar mileage or less if possible and taken care of.
