SB vs BB who wins?
A small block PR is a little over 7 inches. B engines are around 9 inches and the RB stuff is an inch or better than that.
Again, deck height (and by extension) pushrod length is a big deal. Trying to turn 8k on a 7.300 pushrods is far different than turning 8k with 9 inches plus of pushrods.
Details (and geometry) matters.
