I'm still having trouble finding the oil cooler lines. I'm wondering if this truck has the factory big block in it. All the lines that we come up with from the Chevy dealership and Dorman Products has a straight tube that would go into a oil filter adapter plate. Mine does not have that, the cooler lines are curved and go into the bottom of the engine block near the oil filter. I can't find these lines ANYWHERE! Is it possible this is a crate engine or this block came out of another vehicle (dump truck)? Has anybody ever seen this or ran into this?
