I actually started working on that the other day...
Short version: Add .30 to your NHRA index. (which will make it the same as the IHRA index in almost every class)
If you have a Cobra Jet, COPO, or DragPak, you will have an "FX" designation prefix. No change to weight breaks or HP factors -- just separated from the 'traditional' Stockers.
If you are running an IHRA combination that has an equivalent NHRA class, you will run the NHRA class and HP factor: Fuel-Injected cars, Trucks, FWD cars, etc will all run the NHRA classes. Classes V & W will permit both 4 & 6 cylinders like IHRA, but will use NHRA HP factors.
If you are running an IHRA-only class (i.e., Pure Stock, Stock GT, SS/Production), everything's the same as what you normally run. The only change is the Crate Motor indexes will be adjusted down .10 to them more in line with the traditional Stock index of the same weight break.
