I guess I can't have an opinion, eh?
I'm sorry, but I just hate foreign cars. They don't have enough horsepower to suit my taste.
You might consider a little research first.
This is an extreme example, and it's a race car: Let's take a stroll back to 1973: in qualifying tune, the Porsche 917/30, with it's air-cooled 4.5L flat-12 engine, produced 1,580 bhp.
For a more realistic, slightly more modern engine, the M64/60, in the Porsche 911 GT2 (993 model, last of the air-cooled Porsche 911s) cranked out 450 hp, with a displacement of 3.6 liters.
In 1987, the Ferrari F40, with its twin-turbocharged 2.9L V8, cranked out 471 hp.
The 2012 Nissan GT-R's twin-turbocharged 3.8L V6 cranks out 530 hp.
As a juxtoposition, Ford's twin-turbocharged 3.5L, found under the hood of the F-150, Flex, and Taurus SHO, cranks out 365 hp.
Ultimate example of a street-driven vehicle from overseas? The Bugatti Veyron, with its quad-turbocharged 8.0L W16 cranks out 1,001 hp (and drinks a LOT of gas to do it!
)
While I can understand a favorable opinion of large-displacement carbureted V8 engines, having owned a couple of them myself, there is something to be said for the engineering that goes into making an air-cooled flat 6 that displaces less than 4 liters that can produce in excess of 400 hp.
DOHC Ford Modular motors of any description.
So 4.6 DOHC, 5.4 DOHC, and I'll include the Coyote.
While not at the top of my list, those easily make #4. Bet you can't guess why
