All I'm saying is that those engine specs do NOT describe the 428 pistons as having a dish. Just describes them as "Flat w/notches".

So, I'd guess that if a tech guy looked at the top of a piston in somebody's 428 powered Stocker & the piston tops looked just like the 400 Pontiac piston tops, unless they were very familiar with old Pontiac engines, they would OK the pistons, if all they did was just look at the top. UNLESS they had access to more detailed & accurate 428 piston info than what I see that is presented on the Class Racer Info site.

I have run across some info there, that had not been updated to the very latest NHRA info. But, since I figure nobody has planned a 428 Stocker, in a long time, I doubt NHRA has any 428 piston info that is not on the Class Racer Info site.

For me, the bottom line in all this is that the NHRA engine specs(as shown on the Class Racer Info site) do NOT say that 428 pistons must have a dish. And, they do not list any legal replacement pistons. And that's all I'm gonna say about it.

I have no idea what specs NHRA has for those pistons. Dwight / Class Racer Info does a great job in providing information. But it is not perfect.
