Thanks for the info Brian. I'm no expert, but going over some pics of articles I've saved, I would agree with you regarding the features you pointed out. From the few pics I have of my block, I have no markings cast into the bell hounding other than the number 4. At the moment, the block is wrapped in plastic, and I don't won't to remove it as I'm doing some reno work in my workshop.
Attached is the rebuild tag which shows it listed as a "C69T.A". Does the "T" mean truck? I do have the heavy duty oil pan with the oval shaped clean-out. Also, I thought I read somewhere that truck engines were factory relieved. Is this correct?
