Question about the 6.9L

Is this a good engine, or should I look more toward the 7.3 L? I'm looking for decent mileage and long life. I appreciate the help.

As I understand it they have thicker cylinder walls, an `87 6.9 would be hard to beat.

The 87 6.9 is considered to be the best of them all ...
However, Installing the newer Rockers in a late 85 up is the same!

So what year is it!

If you do not know, on the Left (US Drivers) side of the motor UNDER the Oil Cooler is the block casting numbers ... Block casting number translation

-Enjoy
