I believe that Crate Motor Cars that run in IHRA are built with the "spirit" of building a traditional stocker. I think the rules allow 10.5" tires, but I don't know of too may folks who use more than a 9" although I have never looked very close.

While it is true the bottom ends and valve train are after market for most stockers, I don't think anyone would disagree that it is considerably "easier" to use a new aluminum intake and new carburetor as opposed to scouring through junkyards looking for intakes, head castings, and carburetors. I would wager that most who have what is considered a fast traditional carbureted stocker have piles of intakes, heads, and carbs not to mention the time and effort of testing to find out which pieces actually work the best.
Some would argue that crate motor guys could or actually do the same thing, but I would bet most really don't compared with someone who has used what Mr. Hill calls a "little factory iron".

Crate Motor stockers fulfill a niche that IHRA needs, but its pretty clear to me that in most parts of the country, NHRA does not need them.
