Hello fellas, I am looking at buying a 3406B off of a local guy I know for a truck I will be building. No where can the serial number be found. I looked in all the places. What I'm told is it's a 1989 425hp. What info I do have is: Air to air, injection pump 7W3906, Jake assembly C346, Turbo OR6950, Head 1105100 and timing cover has the big cone. I believe it's a later 4MG. Problem is with no serial number the CAT dealership I spoke with told me I can't order parts. Not sure what to do. Can the engine be better identified after tearing the engine down? Thanks
