Here's a great resource. Most of this info is from guys who have running cars and know what works.

I've got a T56 swap thread there with a list of parts you need. There are also lists of what works and what doesn't. It even goes into what rad is the best and gives part numbers. A company called Champion makes a hemi swap rad and its much cheaper than Modern Muscle.
