    These pistons matched with a set of Manley rods, a new stock crank and a Blouch 2.0 XTR turbo our shop car makes 460 wheel hp, and 485 ftlb torque, daily driven. These pistons are top knotch, and Wiseco has never done me wrong.

    • Q: Blew a ringland   JohnM.5 years ago

      Will these fit on the stock block? Just blew a ringland and looking for a new set
      • 0 of 0 people found the following answer helpful

        A:  Stock bore is going to be 99.5mm. These will work but will require some machine work. Depending on the condition of your engine when it is torn apart it wouldn't be a bad idea to clean things up a bit and get better fitment than stock by going with the 99.75mm piston.
