Want to have some fun? I just clicked on 3 of the utube videos at the same time and you can listen to all of them running at once. Takes me back to the 2003 Ford Carlisle 40th Anniversary of the 63.5 Galaxie Lightweights (Reunion). They had about a dozen of them inside a building then fired them all up and drove outside for a photo op. One was a SOHC. These FE's sure sound awesome in concert!
