I pulled my motor apart tonight and found the top ring land gone on one piston. Now I have to figure out what kind of pistons to run. The motor will be a 468 with cast iron rectangular heads and twin turbos running about 10 psi of boost. Should I consider running a hypereutectic piston at this boost level. The inital compression with the hypereutectic pistons will be about 7.5

I'd run nothing but forged pistons.

Isn't 'Hypereautectic' just a fancy word for a cast piston with a high silicon content?

I like to build them with the best parts so you can feel good about it when you have the throttles mashed to the dash

Forged all the way. All Hyper. pistons are good for is dissipating heat faster, but at a cost of strength. Forged pistons are denser therefore hold heat longer, but take more abuse.

I broke one of those pieces of crap on an under 100 hour 454 rebuild. I will never have that problem again! Forged only.

you want forged turbo pistons with extra thick top lands.

Forged

forged is the only safe way to go and i would get a peice made for usng a turbo spend the money now and you won't regret it
