Stronger than a forged ? Maybe a TRW but they were stronger than a Ross, JE, Diamond ect they would be in use for high HP builds.
I have always known them to be somewhere between a good cast piston and a forging, but you can get away with less piston to wall than a forging.

My machinist has been building racing engines for a very long time, over 40 years anyhow. I was surprised to hear him say that. Anyhow I personally don't know other than what I hear from others.
