Very true. In my specific case it's not really the noise, more the feel of having to use more throttle to keep the car at a steady speed and how much engine braking there is when I let off the gas. For me it's more the knowledge that my engine is spinning way faster than it needs to and I'm basically just wasting gas and wearing the engine faster. I know these engines (360/5.9L SBM in my case) were designed to run at 3k RPM all day but I'm sure the Magnums in the '90s trucks were able to last 200k+ miles due to having overdrive and much lower cruising RPMs, in addition to port EFI. Just my $2.00 ($.02 adjusted for inflation lol).
