I think it would be the latest bmw m3 e92 with 4.0L v8 DOHC S65B40
The S65B40 was based on the S85B50 5-litre V10 that powers the E60/E61 M5 and the E63/E64 M6


414 bhp (309 kW; 420 PS) at 8,300 rpm
peak torque at 400 N·m (300 lb·ft) at 3,900 rpm,
power increase of 22% over the E46 M3. The engine weighs 15 kg (33 lb) less than the outgoing six cylinder for a total weight of 202 kg (450 lb)

But in the M3 GTS has 4.4L v8 that produces 450 bhp (336 kW; 456 PS) (not sold in Aus )


I do agree some of the old chevy's ad ford v8 were great in there day but now they old technology that is use in drag racing, nascar and v8 supercars
