Dave, let me know if you hear of any class action suit. They did advertise 10.5:1 and I opted for the Wiseco over 12:1 ones I could have had for the same price. I might have chosen differently if they had been advertised correctly.

I wasn't sure I wanted to increase the compression too much at the time. There must be some advantage to staying nearer a normal compression range although I'm not sure what that might be.

It would cost a fortune to pay to replace all misrepresented pistons with all the labor. It might just put Wiseco out of business. I doubt that would happen. Still, I'd like to know what becomes of all this as I do have a vested interest.
