My dB readings
Stu, dB readings with a 351W, using an auger style muffler, Car Chemistry 3 discs w/o the steel wool packing, no plug in the CC center pipe before the muffler , and a Vortex cone after the muffler. dB Readings are at 50 ft, on hardtop from the side:
Idle: 70
RPM range:

3000: 85
Quick full throttle and immediate release: 89
Used the MAX HOLD setting to retain on the meter the max dB
