I've heard that the sound of the Y is a result of it's firing order, 2, and 1 firing one after the other. A topic concerning 302 and 351 firing orders came up on slick 60s and so I started looking at them. I noticed that the 302 HO and 351 firing orders have the same characteristic, but for cylinders 6 and 5. The earlier 302 and 289 motors have 7 and 8 fire in sequence. If you convert a Chevy to the ford numbering scheme, it is the same as the early Ford small blocks. Other than those similarities, the firing order seems to be a good bit different. Obviously, many things come into play to make the sound of an engine. I thought that was interesting. I'm thinking that the firing order has little to do with it - or at least that aspect of the firing order.
