Engine Swap???
2003 F-250 7.3 diesel. Question, I never haul any loads and my truck is a daily driver. Deisel is more expensive, more expensive to repair. Thinking about an engine swap to a gasser. Does this make sense to do? Too expensive? Better to sell and get another truck? My truck is in great shape, interior is great. Any help appreciated

If it were me, I'd leave it be....
You're talking swapping wire hardness, motor mounts, ECM (or PCM or whatever they're called), etc and a well cared drivetrain for an unknown drivetrain or pricey drivetrain if correctly rebuilt.

He's going to be swapping ALL the wiring under the hood, the dash wiring and dash itself. So he needs to find a donor vehicle to source it from.

That's a very expensive swap. And the truck will lose value. You will be way ahead financially by just keeping the truck.

I am told that the operating expense for a diesel vs a gas truck are about the same. Diesel is higher, but more mpg. Gas is cheaper, less mpg. So switching engines into your current truck will save you nothing on operating costs.

If you're going to go for a gasser, do yourself a favor and look into something newer with the 6.2. A vast improvement over the 5.4 in these trucks (not that it was a bad motor, but it wasn't well-matched to these bricks). You'll also be getting more gears in your trans, which helps offset the mileage difference somewhat.
