Thanks Mike B and Jerry, the truck is at a farm about 18 miles away not far but I don't get there often. Next time I am there I will look into routing the oil line and see what need to be done. So when I get to it I will be installing new oil line not repairing old one. Last year when I first posted about this truck I did post pictures of the block and head casting # and guys informed me I have a 35-36 207 After speaking with the owner he did say the block was replaced in the 90's with NOS block has no serial # on block at all. The flat machined area near fuel pump is smooth no #'s at all.
