Well from another post or is there another same type thread going on this is a 727, the other guys says it was a big block.. sorry I am confused.. All small blocks can have a 727 or a 904 most are 904 except HD apps and trucks.
Even taxi cab /6s have 727s on most. Yes those numbers are corect as per
mrmopartech!
