In 2005 I wrote a number of letters to NHRA on horsepower. I think it was Jim skully I talked to. He suggested that I compare the horse power on my combo with other comparable combination. He said to use as many spec. comparisons as possible to show why mine ..needed to be adjusted down. There was a certain date you need to have you letter in by. Sometimes, you can make matters worse for yourself. Our wagon with 360 was factored at 285HP at that time and same engine was 274HP with same specs in 2 door car ! When the new specs. came out in Jan.... they dropped the 2 door to 270HP and raised our wagon to 289HP..... OUCH
