Identifying Prior Mods to Used V6
OK, I purchased a 2000 Mustang V6. I can see some of the mods done to it and identify the pretty obvious ones. CAI, Underdrive Pully, Exhaust, ect. But how would I go about finding out what the other ones might be without opening up the engine and whatnot?

RE: Identifying Prior Mods to Used V6
To find outif someone installed gears, and find out what gear ratio youhave?
Jack up one tire if you have an open diff, or both tires if you have a working posi or locking differential. Rotate the tire one full revolution for posis and lockers and 2 full revolutions for open diffs. Carefully count the number of full revolutions the driveshaft makes. This is your gear ratio. In other words, if the drive shaft turns 3 ¾ turns, you probably have a 3.73 gear ratio. Turning the tire for twice the number of full revolutions and dividing the drive shaft revolutions by two will give you a more accurate reading.
