1) 8.8, rear solid axle
2) t3650
3) 3.27s
4) 260 crank hp, around 235 rwhp
5) between 14.1-14.4 if you can drive
6) to turn off the traction control, lets you burn out when its off
7) up to you and how much you want to spend, i prefer synthetic.

as to problems, depends how its maintained and driven.

Dammit, you beat me to it, lol.

As for #7, 6 qt's of 5/30, and anything but a Fram filter. And yeah, I know the cap and owner's manual spec 5/20 but real men ignore that kind of bs and run 5/30. Read this... http://www.paladinmicro.com/pmicro....ladinmicro.com/archives/2011/04/entry_29.html

Well the transmission and gears have more than one answer. Don't forget the Auto trans and also there were options for the gears. Most had the 3.27, but I know there were a few released with 3.55 in them as well.

no sir...there have never been 3.55 cars for 2000 nor "other" transmission cars, you either have automatic or Tremec 5 spd...I think the Mach 1s had 3.45s but that is clearly not a 2000 gt

Well as for the trans only the 5 speed manual was listed originally, That is why I said there is an auto option. As for the 3.55 there were over 200 GT's released with this option. The reason I know this, is because my buddies shop (which has been featured in several magazines including Muscle Mustangs and Fast Fords), had a 2003 GT come in with a blown rear. They went to put in the normal gears and as they pulled the old ones, he thought the guy upgraded to 3.55's after seeing what he pulled. He called the owner and asked when he replaced the stock gears with 3.55 and the owner said he has never touched the rear and he was the original owner from day one. The VIN was looked up and sure enough it came with 3.55's from the factory.

That is incorrect. I have access to all the Ford documentation, and the only gear ratio offered in 2003 was 3.27's. That is what they all left the plant with. If it had 3.55's, they were dealer installed.

And I use 5W20 because it eliminated the piston slap in both my old engine, and my current engine. Don't believe everything you hear on the internet about oil weights for the Mustang. 5W20 works just fine, as does just running 5 quarts if the car was originally setup for 5 on the dipstick.

Lighter oil plus less oil equals less windage which means more horsepower in the higher RPM's.

Yea, I don't know then he has every possible hook up at Ford you can imagine and then some, and he showed me the print out when I asked him about it. Ford even sent the first ever Terminator Cobra Convert to his shop for upgrades for a show sponsored by Ford. I would imagine that his print out wasn't lying and not a fake document. Seeing how there are always brand new Fords going there for testing and fitting of new parts. I could be wrong but I doubt it on this one. Just to much background with ford since the 93 Cobra was released up to the present.
