They said these Super Stock Challengers will be very limited in number, and are not street legal, and you should get on the list now if you want one. They sandwiched this info between talking a lot about new block and head castings for old and newer HEMIs, and unveiling the Baja trucks. They also talked about some kind of HEMI block that was made of "Compacted Carbon", which would be in the Mopar parts range."

"Compacted Carbon" So the block is made of diamonds? ;-) I wonder if you can cook an egg on it! Sounds like a pricey option.
