It is gonna take some serious work, but it can be done.
Gas and diesel trannies are not interchangeable with each other.
You are going to need a bigger radiator.
You will need to install two batteries.
You also need to install fuel return lines.
The electrics of the engine will not be to hard.
The weight will be a little more than a gasser.
I do hope it is a heavy duty frame as well, some of the 250 light duty frames would be a little thin.
