I did some more research and I think I found the answer
A normal american v8 uses a cross plane crankshaft and a Ferrari uses a flat plane crankshaft. A flat plane crankshaft makes the two banks of 4 cylinders operate more like two independant inline 4s more than a normal american v8. So a ferrari sounds more like two honda s2000 engines in the same car than the rumble of an american small block.
