What heads are you using. Small port 3v type heads will give you crisper response. So will a small vacuum carb like a Holley 1850.

The Edelbrocks are mechanical secondaries. They aren't necessarily the best idea with the stock 4v heads.

Cam timing and muffler changes will change the growl and sound of the engine too.

The FI Mustangs with the same equipment, i.e., headers, Flowmaster mufflers, agressive cam sound identical to the Holley equipped ones.

The biggest advantage to the FI is tuning with the computer and better cold weather startup and running. Other then that I see little advantage.


Heads are CHI 3V that expand up to the 4V profile to match the IR manifold.
I see FI as far superior in many ways to a carbie.
I had the advantage of having the car tuned by a friend who spent the time on the Dyno setting up ignition & fuel curves at 200 rpm increments at low revs & 500 rpm increments at higher rpm.
So it’s very finely tuned to stay in the 14:1 Air/Fuel ratio & the ignition set accordingly.
What car is still sold off the showroom floor with a carbie?
Sure there are as many economic & production related reasons why car manufacturers all fit injection.
But injection is so much more efficient, not only can it be tuned much more precisely right through the rev range to optimize the engines characteristics, but also more reliable.
Set up correctly it has to produce more power compared to a carbie.
How could it not do so when you have almost infinite adjustment of nearly all the parameters.
It’s simply a more precise & finely tuned tool.

Tony.
