Better Performance Isn't Cheap

Earlier this year, I decided I would make a small change in my restoration plan to make a performance upgrade. I purchased a Wieand Stealth intake and Holley Street Avenger carburetor. This helped performance some but not as much as I expected.

Since the carburetor did not do as much as expected, I just installed new rear gears. I switched from 2.79 gears to 3.25 gears with a TrueTrac differential. I drove it for the first time today and it seems a little faster. However, it does not "feel like an entirely different car" as I've had others state. I would have gone with larger ratio but I a toploader w/o overdrive.

I've tried to stay away from internal engine components as I have so many other things I need to do with the Mustang. Since my Mustang already has dual exhaust, I'm not sure what I want to do next. I should probably stop before I blow all my money trying to make this rust bucket fast. :)
 
A 2.89 to 3.25 isn't that great of a jump, so you'll only feel a little more torque. Going to a 3.50 or larger is much easier to feel.

An intake and carb, without the matching heads and cam won't make much of a difference, IMHO.

I would agree, especially if it still has a stock cam.
 
The good news is that if you dump another $2k into it you can have one helluva engine. I still haven't found out where to stop putting money into my car. :$$$
 
Lunati cam, AFR heads, Aluminum intake :$$$
You have a monster.
Make a bucket in your living room ask your guests to leave empty change for the Stang fund. Just my 2 cents :)
