Yep, bought the whole truck just for the engine. You wouldn't believe how many dead ends I met in trying to buy a good running engine. I was very close to pulling the trigger on an engine online from SWEngines (online) They had an impressive website, they offered a great sounding warranty. But I found a ton of complaints from people that tried to use their warranty due to a bad engine.
I called the company, tried to get more info on the engine they wanted to sell me, but all I got was the run around. Nobody could give me any info on it. They said it was compression tested, leak down tested, and oil pressure tested, but none of the test results were available for me to consider. They transferred me to 3 different people who all assured me the engine meets factory spec's.
I found so many complaints against the company, I backed off. I think all they are doing is taking the engines from wrecked cars, cleaning them up, and selling them as tested. In order to get a replacement engine in the event you get a bad one, you have to ship the first one back at your expense, and they will send you another one.
The truck I bought only cost me $1000. I got to hear it run, drove it, etc. I have a stack of maintenance records with it. The engine purrs! :burnout: and now I have what I know to be a good running engine with a ton of spare parts wrapped around it!
