The best crate motor for the job

[Moody Blues]

I am asking everyone's opinion on what the best crate motor for my truck would be. I have been bouncing between an EFI 572, or the 502 ram jet. My goal is to build the ultimate work truck. It will have to be a daily driver. I have 2 front dana 60 axles that after rebuilding will be going on the truck. The frame will be boxed by the time the motor is purchased. I plan on installing the biggest alternator I can find (amps not girth). I would like it to be fuel injected and gas powered. As soon as I find a 700r4 to rebuild to handle the power that is my tranny of choice, but open to suggestion. The truck will remain looking mostly stock. I will be getting a fisher V-plow to replace the old set up.
