Seems like the crux of the matter would lie in the interpretation of the word "crossbreeding."

When I went to school, "crossbreeding" was a term applied to types of races of PEOPLE... If you had a couple who were of two different races, say a Caucasion and an Oriental, and they had an offspring, its ethnicity would be the product of "crossbreeding."

Applied to automobile engines, I always thought of someone running Ford pistons in a Chevy (or, vice-versa) whenever I saw that language ("No corssbreeding of parts") in the rulebook.

To apply this rule to different engine families, within the product lines of ONE manufacturer would be yet another way of looking at "crossbreeding", but it seems like a stretch to me. It is of no consequence, of course, what ~I~ think...

If that is what NHRA meant, however, when they wrote that, they need to come out and say it.

An official clarification of "crossbreeding" as it applies in this instance, is going to have to come from NHRA Tech.

I hope it's soon.
