    Where can I find a good set of pistons for a 1987 6.2L at a reasonable price? I don't know yet if I need standard bore or +.030"

    What's different between 6.2L Diesel pistons and gasser jug plugs? (I'm not going to try to fit a set of gasser pistons... just curious)

    The differences are the durability and the higher compression. The diesel engine burns many harder and therefore the gasser pistons would be broken immediately.

    In my knowledge, they are only original pistons for the Diesel.

    Mahle makes good 6.2L pistons standard and .030 over. They're 21.3:1 and are around $35 a piece. An interesting bit of news is that Mahle is the brand of pistons that Jaguar and Mercedes use.

    Mahle doesn’t exist any longer. Those were taken up to a federation. MPW (Mahle, Pleuko & Witzemann) manufactures no more pistons for this market.

    If thats true then why does the box for the pistons for my 5.9 Cummins say Mahle on them.

    I don’t know! But MPW manufactures only parts for high-power engines and production machines. Could it be, that your pistons are a production before the bankruptcy?

    Oh sorry I see at the moment, that the concern produced with the name “Mahle” pistons for the american market…
