Truck Repair: ESN, esn number, hp engine

Question
I am trying to find part # for isb275 pistons since they are dual ni anodized. I need them for my over fueled pick up. What I need is a ESN Number from a isb 275 engine. Is this possible?

Thanks,
Randy

Answer
Well Cummins use a CPL(Control or Critical Parts List) for parts like head,cam,pistons,injectors,& turbo.If you are building it to a 275 HP engine then use a CPL for one so parts will be easier to look up.It would take some time to look up but need more info like is it a manual engine or an electronic?
