Re: Stock Piston Acceptance
The piston manufacturer must submit samples to NHRA for approval, and NHRA may require an unmodified OEM piston as a control sample, if they do not already have one.
I've been through the piston approval process, NHRA put us, JE and me, through the wringer, for 6-9 months.
