They do have a different class for them but everyone has jumped ship to the Atlas powered classes because you also get more HP for much less money too.
I think folks built them because the indexes were comparatively soft. Now that the class indices have been CIC'd a few times to bring them into the same (insane) world of money-chasing-performance-gains I haven't seen any rush of new cars in those classes. Do you know of others set to debut new cars? Some racers I know alternate between dragsters/altereds, 4.2s/ Ford 240-300s depending on which index is most favorable.
