I have thought about this today as I drove my tractor around. Just a couple of things to consider.
Personally, at the dragstrips with cars with no mufflers, I have often thought I noticed a difference in the sound of chevy and ford engines of somewhat comparable size and power. I have tried to convince myself that this difference I am noticing is purely anecdotal. Maybe it is anecdotal, maybe not. Like most here I am a bowtie fan and thus I am biased.
I will list the firing of each engine to see if there is a pattern. But first we need to renumber
the cylinders so that we are comparing apples to apples.
For simplicity I will use the sbc/bbc pattern to label the cylinders in both engines, which willindicate numbers 1-3-5-7 on the driver side, and 2-4-6-8 on the opposite side. So forget about the order that Ford used to number their cylinders. The factory numbers are just for identification. What we are after,imo, is if there is a difference in the firing of consecutive cylinders in each bank. AND THERE IS!!
I will use 8 revolutions for each engine as an illustration (2880* cranktrain revolution total), which means there will be 4 fires in each cylinder for this experiment.There is 90* of cranktrain revolution per fire. I will start with cylinder number 1, which is identified the same by both companies (8 is the only other cylinder that fires in the same actual order for the trivia buffs)

Ford LLLRRLRRLLLRRLRRLLLRRLRRLLLRRLRRLLLRRLRRLLLRRLRRLL LRRLRRLLLRRLRR
We see that the driver's side bank fires three consecutive times in the Ford in 720* of cranktrain rotation. The Chevy never does this. The right bank of the Ford has 2 cylinders that fire consecutively twice in each 720* of cranktrain rotation, the Chevy fires a single cylinder in the right bank twice per 720*, and fires 2 consecutive cylinders in the right bank once per 720*.
If there is actually a difference in the sound of the exhaust in these engines, this is the likely cause of the difference. And I think Occam would approve
This was quite a mind bending effort. I think it is only fair as compensation for such effort that someone rewards me with a numbers matching '69 pace car in immaculate condition
