Mechanic Recommendation In Atlanta

[spade]

What shop do you guys trust to work on your Stangs?
I developed a nasty rod knock and need to get it looked at. Wondering if I'm going to need a new motor.
I've looked around but been having a hard time finding who to take it to. I've found Ford Performance Specialist and Higgings Ford Performance online but haven't seen that many reviews or info on them.

Thanks for the help
James
