No.... there are some cars that are just not appropriate for Stock Eliminator, and I think you just named two of them. LOL!
As much as I love the 426 Hemi A-Bodies, I think that running them in Stock would benefit no one.... they were just too much of a race car when Ma Mopar had them built to ever be considered "Stock," but ya gotta love 'em... I do, anyway...
I was thinking more about borderline cases like the '64 Mopar S/S Stage III wedge cars with lightweight front ends, the A990 cars, and certain other low-production cars that couldn't run Stock because of insufficient numbers having been built, like the D-Dart, Buick '87 GNX Grand Nationals, and Z-11 '63 Chevys.... '63 Pontiac Catalinas with the lightweight (swiss cheese) frame, and maybe some Buick Stage II stuff... Ram Air V Pontiac engines...
I'm not that knowledgeable, but I know that over the years, certain factory packages have been dis-allowed in Stock because of low production numbers.
Bringing back the pre-'60 cars would be great, too, but I can't see that happening; too many technical considerations.... NHRA Tech doesn't really need that.... and, that's too bad, because there were some VERY entertaining cars from that period, racing.... before the ban.
