351C Arrow Block

Seen the new Arrow block in AU Street Machine Magazine; ,reads thicker decks,siamesed bores,larger water jackets,four bolt mains,billet caps,solid pan rails and priority mains oiling.Block is 11kg heavier than standard,bore to 4.185 and have .216 bore wall and will take a 4in stroke for a 440cu inch deal doesn’t say about thick main webs and no close up shots of inside block but should make a stout foundation for a tuff clevo.  ~skidsteer member 351C4M
