Could it have been increased to 200 since 2015 then reduced back to 197 1/1/2021? Because the current guide shows the date of 1/1/2021 for the 197 hp rating.

Edited to add: I did a little digging and this combo did get a HP increase at the end of 2018 from 197 to 200.

According to Nitro Joe’s Stats Nanette Stein was running this combo at Sonoma LODRS and ran faster than -.65 in qualifying and first round. If that is indeed true, how did it qualify for a reduction?

DRC lists the entry as an 89 so I’m not sure which is true.

The 1989 would not be correct because it isn't in the guide as a 302 150 factory 200 NHRA rated. It would have to be a 1986 as Nitro Joe indicates. From the AHFS rule book "In addition, the engine family must NOT make two runs of 0.650 or quicker or any run 0.850 or quicker during the past two (2) review periods, for the review to continue."

The Sonoma divisional wasn't a mineshaft race so those two runs alone would have made the combo ineligible IF the NHRA followed their own rule book, but who knows why they do what they do.

That car isn't a 1989 T Bird

Not sure.

There used to be a line on NHRA's site about the 3 year deal. They have since deleted it.
Used to be a combo was not eligible for a reduction for 3 years after an increase.

Re: HP Adjustments are posted
 

You can see from my link it was increased 2 years ago, but the time frame doesn't matter because this is the AHFS rule regarding past increases. "Once an engine family receives a horsepower increase it is not eligible for a decrease."

That is only one of the reasons why it shouldn't be eligible. The other one is what Drew pointed out. That combo had too many runs -.650 or quicker. There are multiple reasons why it wouldn't be eligible based on the rules as written, but it appears those are only suggestions. Or more commonly referred to by the NHRA as "clerical errors."

If the largest HP reduction annually is 2.25% based on a current year run of no quicker than -0.101 to -0.165 how does the 1962 Pontiac 421/ 405 go from 385 HP to 360 HP. 2.25 % of 385 is, after rounding, is 9 HP not 25 HP. It looks like the 227/ 260 Ford received more than 2.25% reduction. After rounding the power should be 254 not the 234.

I would bet that after the first of the year the numbers will be more accurate.

Re: HP Adjustments are posted
 

NHRA posted 11/16/21 as the cutoff date for accepting reduction requests for the 2021 season.
Thank you!

Huh, I sure don't remember asking Santa for three more HP!
