Not quite a conversion...
I'm building a car from scratch and got a 4.8 lr4 from a guy for $250 running. He said it was a junkyard motor that he had put in his Silverado when his motor went out but has now upgraded to a 6.0. He couldn't remember what it came out of other than a truck and didn't know the mileage but says he's put about 30k on it. Do you think a complete tear down and rebuild is nessesary or are there just a few things I could look over?
If it runs fine stock I'm ok with that because I will be shooting for around 1500 lbs for my car so stock performance "should" be enough for a while
