i really cant see them handling that much power.
my forged pistons were only 300 some, and if you plan on running any boost or n2o at all you've gotta go forged, they'll tear the hypers apart.
not true, the key to making hyperutectic pistons last is to AVOID detonation, and make sure fuel supply is adequate.
I sprayed a 200hp shot on my 308 with some speed pro hyper pistons, when I took it out to put in my stroker the pistons looked brand new.
and I beat the hell outta my car all day long with the nitrous, Ive seen many 1993+ 5.0 motors live for years with 15# of boost.
theres nothing wrong with them, and may make more power on a naturally aspirated motor because the pistons expand less and can have a tighter piston to cylinder wall clearance.
problem is, most people dont know how to avoid detonation, once recognized its usually too late. If they were the hot ticket on an NA motor everyone would run them. There a low price pile of junk. When it tears up, your dollars behind if you would have just used a forged slug. Much more forgiving and 95% of people dont have there combination setup correctly in all parameters to take advantage of closer to piston to wall contact, let alone correct hone techniques. The power is in the rings and the cylinder, hone, taper, out of round and concentricity, but people dont want to hear that, they want the cheapest junk possible and Keith Black pistons, forged or hyper are right near the top of the cheap list.

I hear the budget card everyday from the dozens who call me, if 399 for a 2618 forged slug is too much, well so be it. Good luck with your build.
