Yes 2 dr. should be 8.5 ..Watch the wagons..They had a weird one..2 inches wider too.

I must be missing something here. If I'm reading this info correctly, it says that the weight break for N/SA is 14.5 lbs/hp, with an index of 13 flat.
http://www.classracerinfo.com/NHRA_Classes.aspx
This page says a wagon hits 14.50 right on the head, @ 4103 lbs. But I got out the calculator and it says that in order to get those figures, they'd have to be using the 283hp factor for this engine in a Bird.
http://www.classracerinfo.com/Engine...spx?ENGINE=764
But the info on this page clearly says that the 180hp 400 engine was only factored at 283 in the Birds. It is factored at only 260 in everything else. So if this ain't so, now I'm really confused.

So am I just reading the info sheet wrong ? Or, are their calculations wrong ? Shouldn't they be using the 260hp factor for this engine in the Cats, Bonnies and wagons ??? If this info is incorrect, where exactly can I find the correct Stocker info ???
OK, assuming that the hp factor of 260 is correct, Then a 2-door Bonnie Brougham with this engine would have a weight factor of :
3689 lbs / 260hp = 14.19 instead of the 13.04 listed on the Class Racer Info page. So if this is correct, then you could just add weight to make the 14.50 lbs/hp break, which will be an N/SA.
14.50 x 260hp = 3770lbs - 3689 = 81lbs difference
So, you'd need to add 81 lbs to the shipping weight of the car to make the 14.50 weight break.
So. exactly how would I go about finding out if the hp factor is listed wrong on the sheet, or the calculations are done wrong, by using the 283 Bird hp factor for the engine ?
It would be a shame to build a car, going by incorrect info, only to find out at your 1st event tech, that you will be in a completely different class than you planned and built for.
