That was what one of the worst mis-diagnosis I've ever experienced. Car was very loud; especially when revving the engine. So Speedy Mufler removed the CC. (Back when you could.)
Turns out my problem was the fan clutch. In a RWD car the engine turns the fan in front of the rad, and a clutch slows it down to ~700 RPM. So at idle (around 700 RPM) it sounded normal. But rev the engine to 2000-2500 and it sounded like a jet engine. How I discovered the true cause; I heard a loud "THUNK" as one of the fan blades let go and shot itself through the rad.
Yeah, start asking friends who they recommend for mechanics. Get a good one, and treat him well. I've never met a mechanic who didn't like donuts in the morning, or a bottle of booze after doing a long job.
