Hypereutectic pistons and failures related..

My builder--who doesn't seem over 40 years old--was saying how the chrome rings would hold up to the heat and rpms more. True 20 years ago they were used more.

I do know Kieth Black does make them for their Hyper pistons. Looks like I be getting Hypers since forged 340 pistons that are .040 aren't like made anymore. If so I get the chrome rings to keep my builder happy. I had chrome rings on my 318 with 360 heads. For 8 years and no blowing smoke. 3.91 gears and the last few years with 360 heads shifting at 6,500 rpms. I drive 75 mph with traffic on the freeways--so what motor is buzzing around 4,000 rpms. Was ok back in 1969, lol.

It may had smoke a bit warming up but quickly went away in a minute or two. A smoky exhaust on the road is a great way to get a quick traffic ticket..so I get chrome rings again.
