The shop that I own built the engine at 125k miles. It’s got an H&S tune.
It’s had some other modifications to get the fuel mileage up and add power.
As you can see, without a load I’m at 23mpg. We have maintained it using Schaeffer oil. It has been used to haul horses nationwide so it’s always been under a heavy load.
