I have said this before. I was the one who got the piston approved which happened the last few days of Jan 2021. The only thing available before that time (The record set in Nov 2020) had to be a OEM piston. Chrysler doesn't make an oversized piston. You can buy an oversized piston from other vendors but that isn't approved. That is why I worked with Diamond and NHRA to get it excepted. It took a while. Is it stock bore, Left and right offset piston with a press on pin like stock OEM? If so it is good to go or does he claim stock piston and it isn't?
