Andrewh,
Do yourself self a favor. Get a list of things needed then bounce that cost off what you need to put this pallet option as well.
Here was my list
Motor(used)
Headers(pending for what car, tti or jeep srt headers, not sure the year)
Motor mounts buy or fab your own(tti or holley)
Adaptor plate for motor to trans
Computer
Harness
Trans if you need to buy one or use what you have
Efi tank and pump(holley has a nice one)
Oil pan for swap
Radiator and hoses

Even if you buy the pallet option you have other things that add up for you just to put it in and get running. Somewhere either on moparts or on for a bodies only there is a list that someone created. Its a big list but can be smaller if you want it to be. One thing you didnt mentin was your budget. I did my first swap for under 5 grand. It was tuff but i did it. It has evolved since as i stated above. If i have time i will pull my book and share my detail list of parts and costs. I will try to pm that to you. I had some of the efi portion as i had efi on the car when it was raced. That was not factured into the cist, but the factory tank with efi was.

Pm me if you want.
