eng build changed exhaust sound-bad
Stroked a 421 tri-power to 454 with a comp cam. Exhaust is an x pipe with Flow Masters and the 67 HO Exh Manifold and Flow master series 50 muffler. The only change was the stroked eng, but it made the sound terrible in the 1800 to 2300 rpm range. Before with the stock 421 the sound was a nice rumble but now in that range it has kind of a "vrrrrt" sound somewhat like the imports with perf mufflers. Gotta lose that! What to do? Like the sound of Flowmaster.
