I've used Precision Machine Service in Pigeon Forge, Tenn. for my last two Ford motors. Dennis Hawkins is very knowledgable and honest. He has a complete machine shop and dyno in a relatively small shop. It's either just him or one other machinist he hires when things get busy. He primarily builds race engines, prefers Fords, but does it all including antique engines. The shop turns out about 50 engines a year. Dennis was a protege of the late Joe Mondello and was doing Mondello's machine work before Joe died. He's a very straight shooter, kinda humble, charges a fair price, and does excellent work.
