engines (Ferrari does for example) because the same effects of 
 (unevenly) timed flow also come into play in the exhaust. An equal firing 
 interval for each banks gives best performance because it allows the use 
 of tuned exhausts. The disadvantage is that the engine balance is badly 
 influenced (4 cylinder like instead of V8).

mentioned exhaust tuning is the benefit and four cylinder buzziness 
 is the down fall, also the car wouldn't sound as if it had an American 
 V-8 in it,(SLEEPER), but I haven't seen any commercially available with

FYI-  The new Lotus V8 engine used in the new Lotus Esprit V8, uses a flat
plane (180 degree) crankshaft.  The engine is neat, conpact. and lightweight.
 The 3.5 twin turbo V8 puts out 350 hp on the street, and well over 700 hp
for the track.....
