Not sure what size rings he plans to use. They are Hellfires though. He only bought 8, if the setup is right on the money thats all you need

I will get in touch with him tonight and see if i can get some more details.

Good point. very true. Might as well not even think of what might happen if the set up is not correct.

Another nice thing about those pistons is the super thick skirt, (looks to be extra thick from the photo). It's going to be very hard to crack those skirts no matter how bad the tuneup and how much it rattles. I'd say the oil pump would fall off and the rockers would shake loose before those pistons broke.

These pistons (and EVERY piston I use) are always 2618 nitrous/boost alloy. These actual pistons will take more nitrous then you could imagine. 2 stages no problem. That picture is not a optical illusion. It is nearly a .350" thick with a 1/16 ring package. If it wasn't for the daily driven part of it, we would have used a backcut .043 top ring with gas ports and get a .380-.390" ringland similar to what I ran years ago.

Cool stuff man. What's the limits on a 4032 piston?

JE says some of their 4032 pistons are good for mild nitrous use and have a thicker crown for that.

I would call Ross and ask them, it depends on the deck thickness and the ring pack.
