New Engine 4032 alloy Pistons

I picked up a garage sale Callies magnum crank 363 that is supposed to be 10:1. Bearings and everything look good.

The pistons have a good ring pack but for some reason they used 4032 forgings. Don't ask me why.

If I run the 4032 pistons in 1/8th mile use with a good tune, and I stay around 25 psi, what is the likely failure? Just maybe break a ring land? Or will the whole piston come apart?

I can order identical pistons from 2618 and pop them in before running the motor, if it is likely I might hurt something expensive. I really want to be up around 1200 HP, and even with the TFS high ports that power will probably take at least 20 psi. With a big solid turbo roller and 10:1 with the high ports and 7500 RPM, I expect the base power to only be about 600 or so.

Also would I be better off going E85 than C16 race fuel with the harder pistons???
