Default IHRA vs NHRA tech: cannot find IHRA Stock car classification

I cannot find the Stock Car Classification guide nor engine blueprint spec sheets on the IHRA site. (for Stock)

Does IHRA use NHRA's engine spec sheets and car classifications ?

Do they post the different HP ratings anywhere or is that something you have to ask directly for?

Under "Competition Department" then look for horsepower changes down on the right, listed are all changes that are different than NHRA.

I don't think the list is complete. The '67 327/275hp combo is rated at 274 nhra and less in ihra, but isn't listed on the ihra site.

It would be nice if they would just list all of the hp ratings like nhra.
