Chris,
You will not be unhappy with the SPF. I have had no dealings with Dynamic, but have heard many good things about them.
The whole SPF dealer network is great!!!!! They work together to help their customers. I have been to three of them for various things - nothing to do with the quality of the car. Just some things I wanted done or needed.
I would suggest that you look into the Roush motor again, as I recall it comes with a warranty. I don't know if Eric can offer the same.
Just my $.02 worth.
