I guess I'm not understanding why that engine is legal in stock if I wasn't able to buy a car like that, special production run or not, from Ford in 2010?

Thanks again for your help. Sorry for the amateur questions.

It's not a requirement that a certain engine be available from the factory in a certain model anymore. Not like the old days.

Confusing, yes.
All Ford did was submit specs for the 352 and 428 to NHRA and they (NHRA) approved an engine combo that only existed on "paper". Hence the paper motor reference. Ford never built those engines.

As posted above:
352 is a 302 block poked and stroked with Z304 Ford Racing heads and a 4 -blade throttle body.
In stock there has to be the correct part numbers on the intake, t.b., heads and of course the pistons and rods have to be to spec. (among other specs listed in the engine blueprint sheet for the 2010 Ford engines)

That engine is built pretty much from the Ford Racing catalog, for the most part.

To the o.p.:
Congrats on having a 2010 CJ Mustang. Have fun with it !
