One ht eold Carbs, they worked great for better top end...but they don't do
much, if anything, for our FI engines....unless it's a TBI.

They had TB spacers for the 5.0L Mustangs and GB TPI Motors years ago and
they didn't show anything more than a couple of HP. Waste of money unless
it's installed with a carburetor.
