Anyone know where to find HP ratings for IHRA, or are they just going by the NHRA numbers ? I have a 73 Nova with a 307 that is factored with NHRA to the point im not spending a dime on it with that combo. I was wondering if IHRA may have a realistic HP rating for it so that I could actually race the car

One more time. I've stated this 3 times now. They are using NHRA indexes and adding .3.....Simple as that. don't worry about their website. Worry about how they did and entire event...twice. Why would you call them and ignore what they told you...
