Search for the threads on this - it's a tight fit, and is front-axle-crushingly heavy. You also won't have enough wheelbase for serious towing. Noise abatement in the FJ60 will be a big deal, too. Think about all the things affected by this engine - steering, rear axle, brake capacity, tire load capacity, etc. I would buy the Dodge with the 5 speed (or a 7.3 Ford) and tow with that.
