I am rebuilding my 59 235 after it came back from the machine shop. I have searched several times in the manuals but I have not found the piston pin rod bolt torque spec. I can go with the normal 3/8 fine thread torque standard but I would like to know what the Chevy spec is. I found the mains, rods, and head bolt torque but the piston pin I have not found. It would be nice if someone that has that type of info would put it on a spec sheet and sell/market all the torque specs for the old AD trucks. I would buy it

My truck is a 47 3600 but it had this 59 235 in it when I bought it. It sat for 40 some odd years and was stuck tight.
