Re: 4 - 7 firing order swap cam - Vibration reducer?
Hey guys, thanks for replies. I believe it was originally designed to balance air/fuel flow in certain applications, like carb and single-plane intake.
My car now has Accel fuel injection, so I can't imagine I'd get any more power. But it's always nice to reduce NVH (noise, vibration & harshness) and that's what I'd be primarily focused on if I was gonna do this mod. It seems like the manufacturers use the word "smoother" quite often when talking about the 4-7 swap. I am guessing "smoother" means less work for the harmonic damper, but not a noticeably smoother seat-of-the-pants feel in the car.
TexasPP, thanks for the quotes..........
