Ford 6.2L - Thoughts
Thinking about upgrading the truck. Looking for something in the 7-10yr old range. With the Ford, that crosses from the V10 to the newer 6.2L V8. I guess I hadn't been paying attention. Wow, 385...

The 6.8L V10 comes in 2 different varieties. The older one are 2 valve and the newer ones are 3 valve (except on the Econline/E-Series chassis which kept the 2 valve). Big difference in horsepower/torque numbers.
The following were the biggest issues.
The second issue is easily resolved by using an impact wrench on the spark plugs while they are hot.
The 6.2L does not make as much torque as the older V10 but it works well with the current 6 speed transmission and get better fuel economy.

3-valve 5.4 L and 6.8 L engines built before 10/9/07 and 3-valve 4.6 Ls built before 11/30/07 found in many 2004–2008 Ford, Lincoln, and Mercury vehicles have an issue with difficult-to-remove spark plugs, which can cause part of the spark plug to become seized in the cylinder head.
