School me on Stock Eliminator?

hi, well i have to throw a little fuel on the 275/273 class info. I have a 1972 NHRA classification guide. it lists the 1966 D-Dart in stock eliminator. A 2 dr hard top is 10.71 LBs per HP. a 2 dr convertible is 11.11 LBS per HP. there is no listing restricting it to Super Stock only!!!!The only motor listed for SS is the hemi. the weight breaks are different between stock and super stock for the Hemi only!! just thought I'd pass that on.
