The Royal '66 also ran C/S. I assume that was the highest class a '66 could run, in '66. Not sure tho.

Just looked back a few posts & realized that you were asking about the '69 D/SA Judge. From everything I can find out, D was the highest class a '69 could run, that year. That would mean that the D/SA '69 Judge was running the 370hp RA4 engine. As far as I know, the NHRA min weight for a '69 has always been 3500lbs. But I have no idea what the NHRA hp factor was at any given time, back in the old days.
