So a quick back story on my '89 Burb..... Got it from a friend for "free" about a year ago. As we all know, nothings free! lol He bought it a long time ago from a company that used it as a work vehicle who bought it from a private owner back east. Needless to say, it was rode hard and put away wet while being used as a work truck. I've done alot to it in the year I've had it, and it's been running great for me. But it started getting a small knock on the bottom end a few months back, so I knew the inevidible was coming. Cut to last week when I tool a trip down to Colorado Springs to help the very guy I got the Burb from tow a riding mower from his house he just sold. We used his truck for the towing since it's newer, so that's not what killed my motor. Anyhow, on the way back home I noticed my oil pressure was lower than normal. Now I didn't pay a whole lot of attention to it since the gauge went from showing close to 60 pounds all the time to about 30 pounds about 2 months ago. I just figured the oil sending unit was going bad since the engine wasn't showing any other signs of poor oil pressure. Well......I was WRONG! I checked the oil level when I got home and it was barely shoing on the dip stick! And when I checked it the morning before it was fine. So I changed the oil and prayed for the best. No luck! It now smokes at higher rpm's and it rattles and clunks at weird times and at the same time throws more smoke out the pipes. :-( Normally I'd look to the heads for the way it's smoking, but the heads were recently re-done before I got the truck. And the heads might have some issues now that it was run out of oil, but the main culprit in my opinion is the bottom end of the engine. So now I get to the point of this thread...... I was considering pulling the motor and rebuilding the bottom end in my garage. Of course I'd have to get some machine work done first, but it would be the least expensive route. However, I'd have to take the heads apart and check them out and possibly replace parts on those as well since they were possibly hurt from lack of oil too. So now I'm thinking that maybe I'll just opt for a crate motor that comes with some degree of a warranty, which my own build in the garage wont. lol Problem is, I need to find the best option for my truck without spending too much money and at the same time getting someting with a bit more horse power. I think I read somewhere that the 5.7 stock motor is rated something like just over 200 horses? So a 300 to 350 horse crate would be ideal for power without pushing the 700r4 tranny too hard I think. So does anyone know a dealer that sells crate motors in the Littleon Colorado area for a reasonable price that can also make sure I get the correct engine for the year and make of my Suburban? I know I can order them on line, but then you have the shipping cost thing to deal with. Not to mention having to worry about it showing up damaged and having to deal with getting it replaced because of shipping damages.
