Any benefits of running taller velocity stacks/air horns on my 69S MFI?
I have a rebuilt 69S motor and currently going through the MFI system.
The 69S stack openings are huge (largest of the 69-73 MFI variants) at 46mm. It currently has the original plastic air horns which I won't use. It's old plastic that's fragile.
The car is going to be a weekend toy. Likely will have individual mesh filters and fiberglass rain hats.
Curious if there is any benefit to taller or shorter air horns since I need a set.
Thanks.
