Ford Mustang v8 or 5.0, same or different?

What's the difference between a regular Mustang v8/GT or the ones who have the silver 5.0 badge on the side of the car? Or are they the same?
Excuse my noob questions, no mean answers. I'm new, and I wanna learn. I like these cars lol

Oh and I'm talking about newer models like 2011 and up. -thanks.

Can I put a Mustang 3.6L V8 engine in a Nissan 240 SX?

Will the engine fit in it, will it be compatible with the mounts and will the rest of the car handle it the power and weight difference.

Some explanation will be nice. Thanks

Added (1). It has the wiring and "caja de fusibles" which I don't know how to translate. Its the box with all the connections on the engine bay.

New Exedy clutch kit sound?

I have a brand new Ford Mustang boss 302. OEM clutch was sloppy so I had an exedy stage 1 organic clutch + pressure plate and aluminum flywheel put in. Also, changed bearings as we'll.

Went great for a while no noise issues.

I ran it on the highway for to 120mph, but didn't do high rpm shifts. Did around 100 mi of city driving break in. Didn't beat on it.

Now at startup, there's a sound (sounds like a metallic disc spinning) that lasts for like 20 seconds then finally quiets down. What could have gone wrong? What's this sound and where is it coming from?

I changed everything necessary, as mentioned (bearings, etc). No sound at startup. And as I've said it went well before the highway drive.

What could have been the culprit of this new sound?

What is the best air intake for a 2014 v6 mustang?

I can't decide what to get i was thinking either the ford racing intake, the 302 boss intake, lincoln i takes, or bbk. I was thinking about k&n but i feel they are a little over rated. Tell me what you think and give me some more suggestions please!

Which is a better used car to get?

Should I get a Honda Accord or a Ford Mustang for a used car? I only drive around 10 miles a day, at the most. Which one is better overall? Easier/cheaper to maintain? I know the Accord would be better with insurance. I'm trying to get a V6 Accord, or either engine size Mustang. For the year, at least 1996, so it has O.B.D. 2. I want something around the mid 90s-mid 2000s.

Added (1). Oh, and I'm 25, if that would have an effect on the insurance.

Is this the car battery or the alternator?

2000 Ford Mustang V6
Car refuses to turn on

When you put the key in the ignition and turn the key over before you start the rpm's, car mph, temperature all go to the max, and then you hear a 'click' which I believe is the alarm and everything goes back to the lowest. Then when you turning on the car it does not turn it on! At first I heard it crank with a grinding noise, but then I tried 20 minutes and it was a rumbling noise.

dash lights seem to be working, and so are the car lights. But the wipers are moving very slow than usual… And the windows are going VERY slow. I have not driven the car in about 4-5 days… Could this be a dead battery… Or -gulp- even worse, the alternator?

What is wrong with my 2000 Ford Mustang V6?

When I put the key in the ignition everything goes up. The speedometer goes to the max, and so does the temperature, and rpm's

And then it goes back down
And then when I try starting the car… It tries twice, and then you hear a grinding noise. I have no idea what it is

I don't use the Ford as much as I do anymore as it is a weekend car and I haven't driven it in 5 days. What is wrong with it?

Added (1). And when I use my alarm it's not loud anymore…
It used to come from all side of the cars the noise, but now you can only hear it from the hood

Added (2). I rechecked the car. LIghts seem to be working fine, and windows are working but they are SLOWLY going down compared to how usual it is, and now it's not a grinding noise when I try turning it on, it's more of a small rumble. Could it just be a dead battery? If it is, I truly hope so as it is the cheapest option. Starter… Alternator, or solenoid? I'm screwed then

Added (3). And my wipers are going slow

Did I buy a good car system?
