The Hemi in its' true form has been banned from NASCAR since the early 70's. One of the reasons Chrysler left the sport until about 10 yrs ago.
Dodge is introducing their new R6P8 engine with Penske during the earlier part of this season. They will phase out their older R5P7 with the other teams as the season continues. The new engine is no longer based on a production engine, but unlike Chevy and Ford the earlier R5P7 engine, that had such a horsepower advantage over the older Chevy and Ford engine was based only loosely on a production piece.
The block was similar to the LA/Magnum series engines, but the heads were of a newer non-production based design more closely related with a Ford head with spaced intake and exhaust ports.
The factory LA/Magnum head uses Siamese ports on the intake and the center two exhaust ports.
What always made the Dodge engine so strong was the camshaft location and lifter bore size. Both measurements are included in the new design.
A engine like this runs in the neighborhood of $110,000 clams.
