Techs Terry Bell and Mike Baker came up with CM classes for IHRA about 15 years ago and that saved the Stock class in IHRA. They may be somewhat easier to build since they offer easier to find parts, like Holley carbs and unaltered aftermarket intakes. More people know about Holley's than other brands. It also offers a lot of unique combinations using the factory available engine combos. But they still have to follow the blueprint rules. They have their own classes and don't run heads-up with the conventional Stockers. Their under-the-index capabilities are similar to NHRA cars as can be seen at some of the bigger events, but they can get as expensive as the faster NHRA cars as well.

Unfortunately, not as many NHRA legal cars show up at IHRA events even if there are many in the general area, so CM cars tend to be the majority. But new ones pop up from time-to-time.

My main reason for joining was the Holley carb, as I don't know anything about Carter carbs so no NHRA legal combo. IHRA racing overhead tends to be less expensive and events are shorter too.

Pure Stock has a lot of potential. But teardown can be even more complicated and detailed than "regular" Stock. Personally, it's more fun to go faster with the CM option.
