There is Precision in McMinnville that I have used many times.
Excellent quality,,,,,,not cheap by any means,,,but they are a quality shop .
Can do almost anything you want,,,they do everything,,,but used to specialize in Mopar .
They quit building engines and only do machine work now .
I don’t know how far that is from your area,,,I live almost dead center of Tennessee.
I’m not certain but I think their shop is kind of closer to Chattanooga than it is me .
I travel about an hour to them from where I live .
They are usually backed up about 3 weeks or so,,,,depending on what you are needing and cater to the racing crowd so you know they do good work .
Also,,,they do a lot of crank work,,,,they can weld your crank and regrind it into a stroker .
They grind all the cranks for some rebuild place in Nashville if I remember correctly.
