My dad just told me about a like 1990 6.5 Pickup for sale, he said its been there a long time so I want to go take a look see if I can get it cheap. If I go what should I look for? Anything I can tell thats wrong with them? He said its fairly high mileage(guessing over 150k he means). Transmission of course I will look at. How about performance parts for the 6.5er? I couldn't drive a stock 6.5 I would take way too much crap from my friends. I have 4 friends that drive diesels, 1 2000 Powerstroke, 1 97 Powerstroke, 1 12V cummins, and 1 24V Cummins. I wouldn't consider wanting to beat the crap out of them just keep up. And stacks are a must /forums/images/graemlins/smile.gif, Diesel pickups and stacks just go together to me.
