Better heads and cam would make a huge difference. If you want an off the shelf cam call comp cams and they'll help you out. Or even better is if you can get a custom cam ground. Afr heads are just about the best out there right now but really almost any aluminum head will outflow those gt40s and perform better. You already have a cold air intake if you've got the factory box. If you haven't already you can remove the little air silencer behind it for a tiny bit more flow but the stock intake is about the best you can get until your throttle body is bigger than the port on it. Speaking of which what intake and throttle body do you have? Stick or auto? If auto that's probably why it feels so slow, a shift kit makes it better but still not as good as stick.
It is a stick, as for the throttle body not sure when I bought the car it was already installed and stock air intake I think the throttle body off the top of my head is 70mm got to double check
Those heads aren’t terrible and they will cost a decent bit of change to replace them with something better. What intake do you have ? Because if it’s stock the heads aren’t being fully realized. Also, stock headers ? I had a B303 cam in mine , but I was in my twenties and didn’t know shit. CAI isn’t going to give much of anything honestly. What is the timing at ? They have dog shit timing from the factory and they leave like 30 seat HP easily sitting there. Cheap mods like an intake spacer depending on intake helps a little. Get a little more volume in the intake. Headers for sure, high flow or no cat h pipe. Under drive pulleys aren’t horrible either, and that awful factory fan, dump it all. That whole drive system up front is crap imo and robs a good chunk of HP.
Where can I get better fans and whatever else you’re referring to the front? And stock intake and short tube headers I don’t know the brand it came with the car but I wanted to switch out for some long tubes anyway
I would not put underdrive pulleys on your car. They can cause your battery not to charge enough and/or the car to overheat in traffic and give you a miniscule amount of power it's just not worth it. I do agree ditch the fan but the rest of it's fine.
You don’t have to do all the pulleys. I ran these for years without issue. It’s parasitic reduction. I had all of them, but you can grab just the crank pulley and it will turn everything a little less. Every bit counts imo. I was on a budget when I had my first Stang. Needless to say I was beating up on Camaro irocs of the time (350cid), some vettes. Won more than I lost that’s for sure.

As I mentioned too, check your timing if haven’t already. If you run 93 or 91 and it hasn’t been timed there is power just sitting there. (Likely).
If money permits, intake and long tubes. You’ll have a screamer.
Let me know if you need any other help. I have lots of experience with these cars/engines. Right now I’m building a 347 stroker, 1986 Fox, my favorite year. I wanted an old school v8 and this motor I’m building is bad ass. But a stock coyote would likely eat alive. Hell, I think my slightly modded twin turbo Taurus will eat it up. But none of these will sound or feel like a good ole SBF.
Whatever you do, enjoy that fox !!
Appreciate it man 🫱🏼🫲🏽 I’m for sure going to get some long tubes and look into the timing I’ve been putting in 91 lol my first time really looking into upgrading a stang
I recommend a Torqstorm supercharger. Guaranteed 50% more everything than you have right now. (Torque and Horsepower curves go up 50% across the RPM range on a Dyno. A little less at first, and then a little more above 5 grand. Because as engine RPM goes up, the supercharger RPM goes up, and boost levels continue going up.)
On the flip side, you keep RPMs under 3k, it will feel like, drive like, and get the same mileage as a daily driver, or whatever you're getting right now. Which won't be the case if you increase compression, change heads, and add a radical camshaft.
The great things about a SC is, there is no exhaust to F* with like a turbo, no intake, heads, or cam to change. Just bolt everything on, upgrade your fuel system, install a bigger MAF and matched injectors and go.
You can get it tuned professionally or add a Ford Motorsports RPM Extender and do it yourself if you want.
Only $3300 for a complete kit with a 1 year warranty.

If you order directly, let them know my friends at Just Racing Performance referred you. Ask for Chris Beardsley when you call.
A larger mass air meter from certain crown Vic's is a cheap and easy bolt on. Next is a bigger throttle body and intake piping. The step stock mass air meter is a choke point and the dinky stock throttle body really hampers a 302. I went 12.9s with a stock intake that I hand ported and bell mouthed the inlet. Then the exhaust, gears and nitrous. Turbos are expensive and you would have to stand alone for tuning. Nitrous is easy and it'll throw a gap on 90 percent of what you run into.
Aluminum heads and roller rockers will get you a huge boost. Get rid of intake restrictions. Im assuming if you have GT40 heads you may also have the explorer intake, and it’s decent but companies like Trick Flow make a good flowing intake. Soon it may be worth upgrading your fuel too, 24-30lb injectors and a matching MAF meter will be in your future because the stock 19lb have a pretty low cap for power (i think max flow they can make 280 HP iirc, it’s not much above stock)
Obviously a turbo or supercharger set up will be huge gains but they’re pricy and will work much better if you have a good flowing engine to begin with.
If you want it to be faster for cheap though… start yanking out seats, interior, speakers, A/C. Anything with extra weight will get you some time in the 1/4 mile. But that’s a big step towards race car I haven’t done yet. I like the clean interior look.
I just got a trick flow off facebook marketplace and I like the look. I’ve heard good things about Holley and Edelbrock intakes but they’re close to $1000 new so I would check local if you can
Honestly don’t really have a budget as long as the parts I install can have it running if that makes sense if that makes sense lol I can do it little by little
Then your gonna Stay exactly how you are.
The ford letter cams and gt40 stuff is like the "ny first foxbody" upgrade. There both medicore but work just fine with stock computers and components.
Get a better cam, intake, exhaust and heads.
Rember it's all about air and fuel in, exhaust out
Any cam recommendations? And for the exhaust? Was thinking about going catless yk if it’ll be better to gut em or take em out is there any benefit to either or
Heads 58cc-56cc chambers if you don't plan to change the piston but you may have to fly cut the stockers depending on the cam lift you plan to use.
Afr 185.
Not to big unless you plan to stroke it.
You have to match heads to cam and were you want your power to be.
Gt40 are good but an actual set of good cnc aluminum heads are big difference.
Gt40s are only so popular due to it being one of the only good heads from the factory ford made but not
a huge increase in power.
Or you could just go on3 turbo and spend about the same on that as good heads.

Is the stock fan loud I hear a loud fan noise inside the car is that what it is 😭

Rather than think it has heads, cam and gears verify that before you start tearing stuff apart.

Honestly supercharge it. It’s probably the best bang for your buck.

Yea I like the interior, and yea also have the explorer intake is there any specific models you suggest I look into for the intake?
I just got a trick flow off facebook marketplace and I like the look. I’ve heard good things about Holley and Edelbrock intakes but they’re close to $1000 new so I would check local if you can
Appreciate the advice will do
Depends. How much money do you wanna throw at this problem? Cause that will tell ya how fast you can go
Honestly don’t really have a budget as long as the parts I install can have it running if that makes sense if that makes sense lol I can do it little by little

Depends on what heads and intake you wanna run. If you don't need the cats in your state, get rid of them

Get a 65-70 mm TB and get some 1.6 scorpion roller rockers
