Thank you for all the help. Is there anyway to get aditional oil pressure? Does anyone make a high flow oil pump for this truck? Also, once these trucks are fixed up how many miles are they good for? It already has 110,000 on it and I have replaced damn near everything including the head. The only thing that is not new is the lower end. I pulled the crank shaft barings and they are all looking like new. Also, what are these things worth? I have been all over google trying to figure out how many are left in the US and I can't find anything.
