Icon Piston IC982 (specifically designed for boost) has a 34cc dish for use with a 360 running a 4” stroke.

I am going to disagree with you that this is a specifically made piston designed for boosted applications.

Nowhere in my ICON book does it state this, and I can tell you first hand that all the blower pistons I've dealt with will not weigh 489 grams.

While the piston you showi does have a 34cc dish this does not make it a blower piston.
