I just found my 1976 NHRA Rulebook. It shows the weight break at 15.00 to 15.99 for "R". I'm pretty sure that I ran "R" at Indy in '78 and "N" in '79.
I believe between '78 & '79 or thereabouts, they combined the six half-pound weight breaks between "I" & "N" (inclusive) to make the current one pound classes of I, J, & K. Everything else moved up at that time so the '65 Chevelle Wagons became "N" cars instead of "R"s. The 283 has been moved up, down, and around on HP from 220 to 235 in those cars, so who knows what they weighed at any given time. Jerry |

Jerry,
I'm pretty sure that the class change took effect at the beginning of the 78 season. Bob Rice |

I'm pretty sure Jimmy's wagon says SS/Q on it .That would be like the Cieri Bros. in 72-74
(15#) If the wagon was pre the 2dr HT, that would be in the same era. Jimmy Parker could probably tell us about this. I ran at 16 # in 73-74 with the Bel Air 4 dr (SS/R). Later , I remember some 4drs. in SS/T and SS/TA ,so they got moved down a letter for some reason.

I remember now, I think. There was a 12.5 class in S/S (SS/N) Remember Lingenfelter's conv. ? They did away with it for some reason (maybe 75?) and it moved everybody up one letter, below it.

If I remember it, I'll ask Mr. Bridges, next time I talk to him. And I'm fairly sure the wagon came after the two door hardtop.

Mark,
As I stated, there were half pound breaks at least through the '76 year. Bob R. is probably right about '78 being the year. It was then that they consolidated 6 classes into 3 by going to one pound breaks, and that moved everyones class letter designation up some. I remember it happening as my Wagon was an "R" and then became and "N", but wasn't sure of the year. Jerry |

I know I ran R @16 lbs in 73-74 with a full size Chevy. If you take the heaviest 65 Chevelle wagon (3351) and bring the hp down to 210, it's still 15.9... So they must have been 15 lb cars in the late 70's . That's only a move down of one letter (to R) So there had to be only one class removed at first the way I see it. I'm sure Travis could look it up for us when he gets home.
