Of course, NHRA drag racing is only a small part of the whole spectrum of the automotive world, (and again, this is only my opinion...) but, I don't think its significance can be overlooked.
Right, but in the modern realm of the "street legal" actual heads-up racing scene, such as Outlaw, Drag radial, NMCA, etc. Mopars are almost entirely absent.
Of course, most of that is small block, which brings us back to wanting better heads for our small blocks.
