Unless I'm mistaken, The NHRA guide accepted one piston for 70-72, which was actually the higher compression piston from 1970. Using it in a 71 or 72 got you more compression and from the Benisek days (72) forward no one ever corrected it in the guide or in anyones engine. I believe, the story that went around the Buick comunity, was Jason was claiming the car as a 71 but it had "the wrong" 1970 pistons per the 70 spec. AND it was the same piston config everyone with a Buick 455 had run for 20 plus years-just got enforced on him..... This is what I remember from a lifetime of Buick ownership, but is not necassarily what happened here-my memory sucks at this age compared to 20 years ago.
