Yes Sir, ARUSSELL,
I didn't learn this until about 5 yrs. ago, and i have 2 engines with JE pistons in them, 1 a 434" and the other a 377" both on alcohol. There's no question in my mind that JE's are one of the best if not the best pistons on the market. I always look to JE any time i build an engine if they have the combo i need and i've built 3 this yr. for other people, they whine about the price, but they would whine a lot more if it broke.
