To go with GT40 heads or aftermarket depends upon your budget. When I was in High school auto shop, one of my buddies was trying to save up $1500 for heads and cam on a minimum wadge job as his 90GT already had a full intake and full exhaust. As a teenager, a nice set of cylinder heads seemed like a big investment, and the GT40s would have been a viable option. As an adult who has more money to invest in a toy, I would opt for better heads.

[@Ski_zaBoi1776]

I know my podna Dovah gonna be mad but it’s them headlights making that thang stumble like that.

[@paulbalzarano]

Man talk about lack of transparency here. That's so clearly a dynamic graph that shows a car with tired worn out valvesprings. That's precisely why it's cutting out. Not to mention who brings a car to a dyno without fresh plugs and just a good tune up? And those colors regularly make 280 wheel without much work

[@pimpovic2]

Likely because the after video will make a bigger impact when the numbers show a significant increase.

[@TheNova64000]

50Tussin runs GT40 heads on almost all of his foxbodies. He has done videos in the junkyard that looked at various Explorers that had the GT40 heads and intake. You could take the heads intake and even the lower rear end gears out of an explorer and walk out of the junkyard for not alot of money.

[@bigbird7838]

Love 50tussin !!!

[@petemcpeterson6205]

You do all that you may run in the 13s 😂

[@Ares-jx4ep]

@@petemcpeterson6205 13's.. huh. Considering 5.0's were running high 12's with stock HCI (unported) and offroad xpipes to delete the cats when they were new, I'd guess you're about 20 y/0.

[@NGG1983]

that combo should make 260-280 at the wheels so there's something off for sure. Nice looking Fox though, love the Chrome ponies on black.

[@maroonsn95]

I think a trip back with it running healthy is a must video. The car obviously isn't going to dyno well if it isn't running well. It would be nice to see what it can actually out down and not just a speculation range because this combo has been done 1000 times. That's the point of making current content.

[@ricksanchez5696]

I'm doing a simalar setup and making 380hp on my 302 so these guys are messing something up

[@maroonsn95]

@@ricksanchez5696 agreed. This channel is just "ok". He's entertaining and all the fox content is great, but it's kind of all over the place, you don't really get a lot of answers or follow ups and you never see a reply. The other 2 big fox channels offers all of those. We'll probably never see a follow up on this car honestly.

[@danielpope5490]

I would clean the MAF first. Seemed to always make a huge difference for me on my past owned 5.0’s that I had just purchased.

[@BigRockyD]

Same here. I bought an 86 MAF car and it ran like hell in a bad way. Cleaned that first thing and it was like the car got a tune there was so much difference

[@brandonknight7240]

I thought 87 was speed density unless is was converted

[@RinerAutomotive]

I ran a very similar setup for almost 10 years in autocross and this is/was the allowed combo in NASA CMC class. Great, reliable combo that beat up on the bigger guys every event. My power numbers were similar to what you said 240-250 HP/270-280 TQ

[@kevindouglas3275]

Has anyone noticed there’s always an issue when they go to this dyno?

[@bigbird7838]

I agree find a new Dyno guy

[@VictorSanchez-kp9nt]

I was going to say the same thing

[@myeighty-nine7813]

For real! Every single video the dyno just isn't doing its job

[@hotrodray6802]

They're bringing a faulty car to the dyno. Driving it should have revealed the miss.

[@TooBrokeToWheel]

Every time

[@floppyseizure8615]

It definitely seemed like it was cutting out. There’s probably more HP there if it was running under load right.

[@grandspringdale1564]

That beard of doom rules, it RULES🤟

[@Joe-zt2us]

I almost got 300 hp with similir set up. Trick flow intake and shorty header with x pipe other then that same setup. Defenitly broke my heart seeing those low numbers. Get her figured out and try again if you can i feel like you can get 270.

[@harv1974]

Your misfire could be caused by the aftermarket MSD cap to your distributor maybe having a little play in it and at hi rpm it shifts... I know this because it's happened to me.... possibility

[@PeeterPuncher]

sure it is, 50Hp can mean the difference between being able to do a burnout or not.🤣 Would probably be a bit more with better valvesprings.

[@think1stproductions]

So true LMBO

[@nathanieljones7981]

The stock HP can definitely do burnouts. 2nd gear burnouts too.

[@cf88gt]

So here is the thing a lot of people are starting to run into with foxbodies…. Parts are NOT CHEAP anymore….. my combo makes over 370rwhp out of a 306, I have ported victor jrs, a ported systemax, and High rev dual valve springs, Ed Curtis .600+ lift custom grind cam… most of my parts are over 20 years old, the top end alone would cost Over 5k to replicate in today’s dollars…. The cars are expensive, the parts are expensive , and the cheaper/ budget parts are not going to do the trick…. You absolutely have to be above 300rwhp to begin to start having enough power to hang with these newer cars… A lot of guys have the money to throw at them, and buy all the fancy parts… but it’s just HARD to do nowadays on a budget!! As soon as I heard that car had 40p heads, I knew it most likely wouldn’t make over 240rwhp.

[@VictorSanchez-kp9nt]

Richard Holdner

[@cf88gt]

No doubt, I didn’t say it was impossible, just not like the old days where you could easily slap a cheap fast combo together. Everything is more expensive these days, and that changes the way people feel about “Bang for their Buck” I LOVE Foxbodys, but if I didn’t own mine I’d just start with a newer faster platform, you can literally buy a 12 second 2012 5.0 GT for what a decent Foxbody is going to cost now.

[@midnight347]

It should def be doing more. 260-280 shouldn't be an issue with a setup like this it has an issue that is causing power loss. You seem to have a solid comb 370 is very respectable out of a 306 but you can easily make 300 or better with a budget hci setup and fbo with say a ported explorer head and intake Combo with a decent cam.

[@cf88gt]

@@midnight347 I’ve built dozens of combos, I’ve seen it all… I made 297 at the in 1999 with aluminum heads, a cobra intake and a b cam….300 at then tire used to be the gold standard an easy combo , I made 325 and trapped 116mph in 2004 with afr 165s, a custom grind, and a performer 2 intake… gt40p heads just don’t make power… a gt40p head ported by big dogs or someone like that, and a fully ported explorer intake, with the right cam, on the perfect day can make 300…. I have NEVER seen a gt40p headed car make an impressive number… I not saying it can’t sound good, and be fun to drive… but people have to be realistic and no what to expect…. 280-300 at the tire is a HUGE goal, that MOST , not all, but most combos will not accomplish without a solid head and at least a longer runner style intake…. You can do it on a cobra/gt40 but it will be hard.

[@angrygaragemechanic]

Something is seriously wrong with the car. I've seen similar combos get close to 300

[@95Sn95]

The sn95 5.0 Dyno runs I've seen have been down in the 175hp range and the GT had the bigger fox cobra maf. I think the only other difference is that gooseneck on the intake and a more powerful ECU. One of the coolest diy mods I've seen was a video where a guy put a micro switch on his throttle (it was an old Mopar but doesn't matter) that when it was at WOT it shut the alternator off so it caused no load on the engine by grounding the regulator or whatever. But being only at wot there's no voltage problems, great idea imo.

[@Mustang5L5]

Had a similar issue on my car. Anything over 3k RpM would have the car fall on its face feel like it was misfiring at higher RPM. Pulled my hair out for a year chasing it thinking it was fuel. Ended up being the crappy Accel coil. Swapped it out and it ran beautifully after that.

[@ilike9s]

I wanna see the tractor on the dyno.

[@kpsgarage]

Things I try to do before heading to the dyno: Oil change Fresh spark plugs (confirm correct ones) and inspect plug wires New fuel filter Inspect timing Maybe one of the above causing the cut out???

[@johneldorado]

Seriously, why waste expensive dyno time before getting the basics dialed in first?

[@chrisbarnes8887]

Something seems off to me. I know the 89 coupe I used to own had a similar setup. E cam, the aluminum gt40 heads and I had the BBK ssi intake and it put 290hp and 305 torque to the ground on a mustang dyno and the car ran mid to low 12’s all day long.

[@pimpovic2]

Sounds worth it to me!

[@michaeldemos6816]

No gain it torque?

[@hotrodray6802]

THAT IS NOT a similar set up

[@randumadventures]

Did they upgrade the junk factory P head valve springs? With a alphabet cam and stock springs I’d put my money on there is the miss fire and low power

[@thacutoff6226]

Think there is issue with the springs, if they are stock gt40p springs that can make a big difference. Nice upgraded springs diy valve job and home porting on heads and intake and your in business

[@CalypsoCoyote]

Plan on getting my gt40 intakes and 3 bar heads ported and running with that combo.

[@Robx5.0]

I got the exact same setup,+ X-pipe. It's reliable and fun for a daily. Today my sve throttle body and cold air kit came in, idk if it's gonna hurt it or wake it up.

[@floydmarseeii4007]

Cool, with a little tuning and maybe some valve springs, I believe it will take off.

[@utahcountypicazospage5412]

Might be better to save a little more money and get something better because the cars/trucks today are hard to compete with if you don’t have at least 330 wheel or so fox can have a little less because it’s light but 400hp wheel is usually what you need for 3600lbs or so

[@hotrodray6802]

Oh, you're building to please somebody else. Got it

[@roythomasjohnson2341]

thanks, carb and intake going on...

[@markstruck7517]

Why would you want “crank horse power” on a Dyno?

[@grandspringdale1564]

I would argue that anything more than the 225 she has from the factory is a decent improvement🤔

[@centraltexasfoxbodies]

Makes me feel better about about my 4.6 2v in my 79 mustang, I ran mine on the dyno and timing stuck on 10 degrees and I made 196hp and 240 ft lbs, that's with pi head swap and comp xe274h cams and stock manifolds catless h pipe, and 75mm throttle body, I have since gone terminator x and saving up to get it dyno tuned again. Hoping for 260 whp so seeing this makes me happy that I should make the same if not more power than a HCI 5.0

[@chrishansen7004]

Get the trickflow top end kit for the 2V, night and day difference, I'd imagine it could get ya 400rwhp even more bored and stroked too a 5.3L. the cylinder heads are a huge bottleneck on these modulars I imagine a hand ported set of pi heads and a short runner intake you could easily break 300rwhp

[@centraltexasfoxbodies]

@@chrishansen7004 for the price of the trickflow heads I can piece together a blower kit.

[@joshhuffine4522]

My identical LX made 222.3hp on a very very similar setup.. I didn't have the true tubular intake, I just had a explorer intake.

[@The83turbo]

If I was throwing rocks at the issue I’d bet it’s the SUV valve springs giving up in the high RPMs 😬

[@hotrodray6802]

Valve bounce in the mid range too

[@Bacongrease00]

If I’m slapping heads on it at least go with the budget TFS170 or AFR enforcer series

[@jakew2350]

The most you can make with that combo is about 240-250 whp. The heads and intake really won't flow any more.

Average stock P heads can support 360 HP. (180x2) There's other limiting factors.

50 horsepower is doable. Just some loss odds and ends need to be ironed out.

Great video.

[@JoelFJB]

I would have been disappointed

[@msk3905]

Not sure why you wanted to run it higher than 5,600rpm the B or E just won't make power past there. I ran a ported E7 with larger vlv's with a B303 and GT40 intake lower ported, made peak power 5,400rpm...made 268rwhp 304rwtq on dyno-jet dyno. also, please tell me that the 15.51 afr is wrong or I am reading that wrong

[@BIGDMEDIA]

Good Video!!

[@autofox5.067]

I have never had my car or had any experience on a dyno. But having said that wouldn’t the power curve be more valuable information than the actual overall output numbers? If Im wanting more power on the street then getting higher numbers in lower rpms is more important to me than at higher. Im just asking/saying that this combo may feel better than the numbers show if it starts making power earlier than the stock heads. I have a set of GT 40 3 bars that Im hoping to get on mine soon.

[@johneldorado]

Great video, beautiful car, but really poor numbers. I just don't think it's worth all of that work for like 40hp over stock. If I had a classic 5.0 like that, I'd just maybe throw gears in it and call it a day. Have fun in a classic and dont worry about losing a drag race.

[@zip1233]

tldr unless you get these heads and such for basically free, no it's not worth it. for 3500ish you can get an on3 kit and everything you need to make double the power reliably.

[@matt6951]

And people wonder why these cars get ls swapped.

[@midnight347]

Dude similar combos make close to 300 all day long there is clearly something wrong with the car. You can make well above 300 to the tire with a good setup on a stock bottom end low compression 5 liter. This car is clearly down on power because something is wrong. There's plenty of ways to make power with a ford there is absolutely no need for an ls anywhere near a mustang.
