Mustang v6 or v8?
V8! It's a Mustang. I know they have a V6 model at a lower cost but often times the power to weight ratio doesn't mean you'll get better mileage with the 6. Besides it's a MUSCLE car bigger is better.
Easy! 8, but cobra if you can. More horsepower because they have a 32 valve engine. What year are you looking at?
Mustang v8, bigger engine. Goes faster. But the v6 would probably have better gas mileage.
No question. Nothing to do here. Could've had a V8.
If you like speed then v8
Is this a rhetorical question?
