I've seen those photos too & that gets to my confusion & question.
If the cars were really RO23 Belvederes with W/P=7.59, it seems they'd have to run in the SS/7.00 (W/P) class. That was SS/B in 1967 or SS/C in 1968. It wouldn't matter to NHRA if they had GTX or Imperial or Chevelle painted on the side, its still an RO23 car so would have to run in the W/P=7.00-7.69 class, right?


Now, a real 67 Hemi GTX would have W/P=7.75 so It would run in the SS/7.70 class. That was SS/C in 1967 or SS/D in 1968. But either way, you'd have to run a GTX hood with no cold air. IIRC you couldn't just add cold air induction to a car model that didn't come that way, right?


So my thinking now is, to run a B-Body Hemi in the SS/7.70 class, it had to have a flat hood without Functioning cold air- UNLESS, maybe I missed it, was there a factory cold air option for the 1968 Hemi GTX and Coronet R/T?
