Looking for to see if this is a good number. There is a spot in the block that has a slight grind mark and the digits appear to be marked by a center punch. No tag anywhere other than on the aftermarket turbo. I went to look at this engine today for a customer. I what I think were part numbers on the injector and the printed numbers on the tops are all different. Should they all be the same or not. Thanks for any info.
That number comes to a 3406E with unit injectors. Bob
Those 4 digit printed numbers may be trim codes.
