6.2 diesel vs. Gasoline considering dually

[lindstromjd]

Depends on what you want to use it for, really. If you want a powerhouse for towing, then you'd be better off with a big block 454. If you want better fuel mileage, then the diesel is your friend. Think of it this way... a non-turbo 6.2 is ABOUT the same power curve as a TBI 305. A turbo'd 6.2 is about like a TBI 350. But, they get upper teens easily for fuel mileage with a TH400. Can't beat that at all with a gasser engine, especially not a big block.

There are a lot of good informative threads on here about what to look for with a 6.2 diesel. Search for them, and if you still have questions, then don't hesitate to ask.
