My F430 buzzed the Aston burbles if you know what I mean , so the flat plain fires two cylinders at a time like two fours on a common crank with no counter weights , so revs quicker and higher.Aston V8 has an uneven fire patern on each bank of four but even overall , however you can't disperse fire pattern in the way you can in a 10 or 12 , so two cylinders will always fight for exhaust hence the burble .So I have been told ? I have searched the web and seems about right , lots of technical stuff about degrees of pins etc but Aston V8 deffo cross plain

Apparently if you look down the length of the crank you see a cross . Hence the name and the flat looks , well flat.
