That's what I was thinking.
5 minutes to fill out the form.

Worst that could happen is they say no.

Of course the person filling out the request would have to be the driver that drove that combo at a national or Divisional event this year.

Just have to get it done before the Monday after the World Finals in November.

Ya can't make this stuff up!

Now I am really confused...…

69 ChevyII 111" WB vs 68 Camaro 108" WB both rated the same 235/255/280HP

69 Impala Sport 119" WB rated 350/255/275HP...
69 Full Size SW 119" WB rated 350/255/263HP = 12HP less

69 Chevelle 2 door 112" WB & 4 door 116" WB both rated the same 350/255/280HP
69 Chevelle SW 116" WB rated 350/255/275HP
69 Chevelle SW & 4 door same 116" WB = 5HP difference

You have to request HP off a given combo. If it qualifies for a reduction, that specific combo will get reduced. Similar platform combo's may also get reduced, but only that specific year. I had my 1978 Nova 305/145 reduced, and they reduced the Buick, Pontiac, and Oldsmobile versions of the Nova with the exact same motor as well, but only in 1978. No other cars/body styles were reduced. There are criteria for minimum, maximums, and average et's for the combo that determine eligibility for reduction and how much. Those are spelled out in the NHRAracer website under the Automatic Horsepower Factor System link.

Fill out the form, never hurts to ask!

This horsepower thing has really got out of hand.
For me an engine hp rating is just that, stick,auto long/short wheelbase, convertible etc.
The biggest reason for this result came when they allowed the combo's to move up one Class,that meaning the same Cars could dominate one more class,thus other Cars started need some help and there we went!
Before that rule was changed the classes where protected from certain Cars.
