Later model 3.8 swap in an "A" body

I always liked the way the 3.7l ran in my 04 Liberty.I know it liked to rev and always wondered how it would work with a 5 speed and a nice set if headers and even a power programmer.

The 3.7 L was a 90° v-6 where the 3.3 L/3.8 L were 60° v-6's. The 60° engines have better/less harmonics.
