Contemplating a Swap

Thanks for the response 5.7. Does anyone make a complete swap kit?

I know the TTI mounts and headers seem to be the favorite, and an oil pan from different companies are a must, but I have been coming across differences regarding the computer and harness.

I take it I can redo the computer, but need to have the mechanic create a harness for me?

Sorry for newbie questions but I just don't want to get over my head.
