Re: IHRA HP Rating 1973 - 2 BBL 307 Nova ?
One more time ?
I?ve never asked this. In fact I never even inquired about it until today - lol. To add more mystery to the equation at the last race the indexes were 6 tenths slower
A/SA was 11.60
E/SA was 12.30
J/SA was 13.05
Those were the only ones I could figure out from the live stream angles during Q4.
