Thank you for doing 5.0L stuff for us Richard, many of us out here appreciate your efforts 👍
Yea fr ✊🏾
My pleasure
And the ford modified video was cool! It's an underbuilt machine and your proved it!!
Yeah, seriously I've been applying what you have found and shown on Ford stuff in conjunction with the stuff I've learned on Engine Masters and it is helping a ton when looking at engine math books and such to come up with my combination....this will be a mostly home build and I want everything to be as good as it is going to be and WORK. And I believe it will with what you teach and some of your colleagues teachm
Absolutely
Love 5.0 pushrod stuff 👌
GT40 intake, B303, Longtubes, Flowmaster 40s.
The meanest sounding 250hp ever.
Not to mention the best sounding 👍🏻
I used to eat those all the time back when i had my Taurus SHO, both the drag strip and highway pulls. They didn't stand a chance lol
Was that with e7 heads?
@@TommyboyGTP that 7k redline helps. And as does the part about Yamaha making some badass heads.. 220~hp and 215tq (according to a forum or 2) and that power comes on fast. Imagine if they'd have offered that little v6 in a rwd.. (it's doable buuutt..)
@@PureCountryof91 I'm pretty sure that was a very conservative power rating, and yea it pulled like a beast, and would go to 7,500 or a bit more before the cutoff. Used to rev the piss out of mine, it loved it lol
Awesome content keeping the old school 5.0 alive!! And it helps us guys who don’t have a dyno.. thanks Richard!
Thanks for great content. You have spent So much time to help others see what combinations work well. I think all of your followers would agree you are a phenomenal teacher.
I appreciate that!
@@richardholdener1727 if you could swap in a mild 302 in anything, what would you pick and why? Not for racing but just to have for fun on the street. Like a pinto, ranger, maverick, ect?
Thanks for all that hard work! Lots of great information there!
Thanks for all the time and effort you put into these codes videos
You bet
Absolutely blown away by the amount of content you crank out. Very interesting content!
Glad you enjoy it!
This is a great video on showing how important matching the engine parts combo is. I have so many friends that are disappointed when they do a string of bolt ons that are not matched or leave off some parts to save money and their cars are not much better than stock.
Thank you for doing actual informative videos. It gets really old watching people's attempts at movie making and crap reality show type stuff.
Awesome video! thank you for making it!
Thank you for this info, keep up the good work.
thankie sir, ya know you make it so easy to build a good engine due to real life testing i greatly appreciate your time and effort
Very welcome
Please test the Holley hi-Ram intake manifold on the 351w!! If possible put those r11 trick flow heads too
Amazing stuff you do thank you.
Another great video.
Thanks for showing us the 5.0 intake differences. I have a 306 with milled afr 165 heads at 54cc. Stock cam with svo rockers with close to 10:1 compression. I used the cobra intake. I was able to produce 355rwtq at 4000rpm. Great video, keep up the outstanding work :)
I have a 331 10:1 with a gt40 tubular, china heads, XE270 cam, aluminum china heads, shorty headers made 315whp/360 tq
Stock 5.0 cam in a 306?
Thank you Richard!
I would of loved to see some of the old 5.0/5.8 truck intakes included in this test
I second that! Us EFI 5.8 guys don't really have a junkyard option for the lower intake, unless you're lucky enough to find a first gen Lightning in the Junkyard, which would be like hitting the jackpot. Most have to spend over $900 for the Edelbrock stuff.
Love this channel. Would love to see a test on a 351 before and after port and polishing to see if it's worth the effort. Maybe a comparison at same compression between stock, stock with p/polish, then after market heads on same engine to see the cost/benefit of each. Thanks Richard
Gotta love those compounded HP gains. Don't forget the decal horsepower, either!
excellent info! i gave up trying to explain this, but maybe people will listen to you!
Great video
I have a Holley Systemax II, with Trick Flow 11r 190 heads and an Anderson N-41 cam. Goes like gangbusters.
Thats a killer set of heads. Best overall on the market imho at least for a street car
So for those asking about extrude honing, i do not remember what year it became popular in hotrodding but early 90's seems to be close to my memory. It's uses a grinding media in a putty like form pressed thru passages to open up and clean them of blockages and in the automotive world to port efi intakes because some of them are impossible to port any other way. It can be used to great effectiveness to add power around a peak not change the actual peak power rpm. it's like porting but with silly putty and a big assed hydraulic ram.
it is industrial grade silly putty impregnated with silicone carbide (or even industrial diamonds on some applications)
Should do a intake shoot out. That would include trick flow as well
The hp on last test is nice but that torque curve is what I like.
Should have contacted Bigdogs porting and tried one of their stage 2 and stage 3 ported Explorer/Cobra gt40s. The results would have been shocking.
Run plenty of ported (and modded) Cobras and GT40s over the last 30 years or so-we know what they do
@@richardholdener1727 so you know a what a cut, runners shortened to peak at 6,500rpm, 2.4 mcsa, 320cfm bolted together average runner flow with a 80mm 1,100cfm throttle body tunnel flow gt40 would have made 30plus hp more than any of the tested aftermarket manifolds. To many that would be a better test because it's doing something different than buying what everyone else has bought and getting the same limitations everyone has. We have plenty of back to back testing and we have found it hard to beat a properly ported/modified gt40 manifold.
This is a good test though. Keep up the great work!👍
@@richardholdener1727I’d really like to see you do one of his intakes . Everybody in the forums would like to see it .
Really enjoyed the 302 and gt40.
Haha I remember everyone that was into mustangs 20 years ago did what you’re talking about with stacking the horsepower gains.
Waiting for the Aspirin giveaway for all the minds being blown...
It would’ve been cool to see what the factory ho intake and gt40 would’ve done when they had the extrude hone treatment. I’d bet the hp numbers would’ve been very similar without the tq loss on this mild combo. I love all this info. Also second a junkyard gt 40 head and intake combo with a Motorsport alphabet cam. Thanks for the vids.
The tube GT-40 can't be ported-but the Cobra version can
Awesome to see some of your 5.0l ford testing, what about a comparison between an RPM air gap carby manifold and an EFI manifold like the RPM 2 for those thinking of converting from one to the other, keep up the great content Richard, by far my favourite you tuber
Not a bad idea. I’ll guesstimate that the carb will make more power up top, above 4600 RPM, and the efi will make more down low.
I did that test
I realise that you have most likely ran this test in the past as well as tons more I’m just waiting anxiously for you to share the results keep up the good work
@@richardholdener1727 have you posted it here ?
@@brettkelly1436 he did share the results
I just saw one of the tubular intakes sell for $1200 on a FB group. People are nutty over these intakes.
I sold one I had on eBay for $875 two years ago. People definitely love them still. Not sure if it’s more for nostalgia or just the cool tubular looks.
@@CentralVAracer I’m new to the fox body. Just got one with shorty bbk, e303 cam and bbk cold air with flow masters. She runs out of breath at 5k rpm but feels great down low. What’s the best bang for the buck manifold?
One of the big 5.0 Mustang magazines in the day, did a dyno test of intake manifolds. Found the low riser OEM intake used in T'birds and 94 GT Mustangs wasn't as restrictive as thought. That an Extrude Honed stock HO intake could match a GT40--when they were new and expensive, it was a consideration, tho Ron Anderson Performance could port one out and really make some dyno numbers. I would imagine an Extrude Honed Cobra or Explorer could do better, since you aren't going to hone a GT40 tubular.
Holley's Systamax reminds me of the $1,000 Saleen intake.
Wow. Thats a big jump in power from an intake. I estimated 60hp for the exaggerated test.
Anyone see what the Foxbody Mustangs & the 1993 Cobra Mustangs were going for at Mecum Indianapolis 2022?? They are getting the appreciation they deserve, I'll just say that!
I wanna see more 4cy and even 6cyl motors. CMON RICH , your roots are in 4 bangers man. Let's see some honda big bangs and how about a supercharged mini 1.6l big bang
Look at the Big bang Honda video that is up-along with many others (including V6s)
I would like to see what a stock 5.0l truck intake is good for
I would like the carbureted efi intake tests with like the spyder intake, pro m intake, Victor junior , trickflow. All of the carbureted style efi ones.
can you compare differences between throttle body injection like Fitech vs a port injection style like the one used in this video?
I'd love to see a nmra factory stock motor with all the tricks done up on that dyno 😉
That would be cool!
I think you could achieve the same sort of power with far less money spent by using a single four barrel carby and Victor Jr or the motorsport intake on a 351 or 347ci stroker, and stock GT-40 heads with a bowl blend.
Right on
For the bank that was involved in one of these I think I'd just turbo it until it split down the middle then do a 351W in its place. Ford really did do the intake right though in terms of being able to modify it, GM had the TPI which looked cool but wasn't that great overall.
Hey Mr holdener i wanted to say thank you for your time i have learned so much. I think iam decided on my 351 and parts combo TFS top end kit with the 11r's and there efi and a cx gt45 turbo . the only thing is i don't know much about tuning especially with a turbo . where's a good place to start?
11:1 AF and very low timing
@@richardholdener1727 thank you
Richard, have you ever dyno'd a 5.0 with the old "pistons-in-backwards" trick to actually see if that adds the magical 15hp that people used to talk about?
Ever tested any fabricated "box" upper intakes? Curious how they stack up. Have a friend running a ported/extrude honed GT40 lower with an aluminum box upper on his 331 stroker. It seems to work well, but the new Holley hi ram for the SBFs have him looking at other options. I think it will give up too much under the curve unless he goes with a big solid roller and larger cylinder heads.
Hi would be better than box
Would love to see some truck 351w stuff or some 302 truck stuff, not alot of dyno numbers or dyno proven upgrade items on the truck Windsor motors
there are a few 351W videos up
Do ford 300 4.9 build up
I built one found rare industrial ford 300 had 4.120 bore I placed common crank 4.00 stroke came to like 320 ish. I was young found out later it also had forge crank. And I made custom intake and exhaust dual I think 70mm throttle body one on for runner each and twin turbo , h beam rod full roller timing systems, and fully hand ported stage4 like port and polished and port matching and over sized valves
In these test that made the most power.. what size injectors, throttle body and mass air meter were you using?? Thanks for the videos!!
no maf-it was speed density-36 or 42 pound injectors
What intake for a 363 Stroker for the street? What is the hp limit on the gt40 or the Holley? I want one that has the leaned over runners like stock that flows enough for a big Stroker.
these intakes have been around a long time, I need to see what a Holley HI RAM with a side mount ford throttle body can do, can it beat the gt40 under the curve? can you borrow a professionally ported lower for the gt40 so its potential can be seen.
I just sat on the toilet, perfect timing! Haha
TMI
Lol
Haha i can relate 😂
Me too! 😜
so basically the e7's are the bottleneck that need to go first? intake and cam do little with stock heads?
A intake comparison with forced induction would be nice primarily a centrifugal blower or turbo setup.
Intakes do the same thing under boost-tested that many times
@@richardholdener1727 Thanks for the info
Whats your opinion on holley Systemax heads? I'm aiming for around 300whp stock 94 bottom end, holley systemax heads, XE276HR Cam, GT40 intake and long tube headers with Mac prochamber exhaust. Think I'll be close ?
No dyno sound? I missed the "Weeeeeeeeeeeeeeeeehhhhhhhhhhhhhhhhhh! Lol
You might not notice 24ft lbs missing, it's lots but it's like 7%. You will definitely notice 40hp especially when you can run it 1000rpm higher. You would only see that rpm once on the strip, and even then maybe never.
Hello brother JT here was wondering your take on the Coyote ford motor that they are putting in the F150s
they make good power
Hey Richard... Could you test the Holley High Ram or Sniper intake for Ford please? I'm interested in how much of a difference that makes.
i have one
Well stated sir. It's like buying an air filter that promises up to 45 hp gain... lmao Love the videos. keep em coming. Kinda wondering about the results of changing nothing more than LSA on an already somewhat efficient combo. I'm used to the 106 to 104 LSA cams even thou idle quality isn't very good unless compression is real good. In a street car though a vacuum brake booster becomes worthless. (maybe a hydraboost system would fix that idea though?) Just a thought.. Thanks again sir..
the lsa video is up (on an ls application)-tighter can improve power low and mid but does lose idle quality
@@richardholdener1727 how do i find that lsa vjo?
@@jlfastride1 Search for "lsa" on his channel. Here it is: th-cam.com/video/JUHwVCDjonU/w-d-xo.html
When my mom passed I got her 95 GT convertible 5.0 5 speed, it's pretty soft I mean it scoots along nice but definitely isn't "fast" plus it's blessed with 2:73 gears! Woohoo. I do like the cruise rpm but the gears seem so tall you can turn it to around 55 in 2nd! Anyway I've been researching engine mods and I'm a little discouraged at the gains and all out HP of the 5.0, I'm used to the gains of chevy 350s where 350hp+ is effortless. With 302s 300/325hp isnt as easy and 400hp seems pretty stout for a 302. Am I wasting my money trying to make the 5.0 powerful...? Seems like the only way to have decent power without spending alot of money to get that little 302 is cam n turbo the 5.0 for around 400hp or building a 350 to 375hp 351... I would think even 350 NA HP or 400 HP mild turbo in a sn95 would be pretty respectable street car...maybe where a has a T5 a little deeper gear like a 3.40/3.50 so I can still have a comfortable cruise rpm.
I would like to see the same engine with a carb vs efi challenge. My 1994 5.0 was carb swapped and people say it makes less hp than stock
depends on the intake. The long runners of the EFI would get whipped by a single plane, above 4,500 RPM. But a carb cools the intake charge with the venturi effect of its "barrels", while the typical EFI intake has so much surface area, it soaks up a ton of heat. And with the shock towers in the engine compartment blocking airflow from rad to firewall, there's a lot of engine heat to soak up.
Anyone put the Sniper EFI from Holley on the 5.0 HO??? I Love how all V8 Engines look with those types of EFIs on them. I think you would need the cowl hood to install in a foxbody tho. I would get the hood just for that!
Hey Richard. Have you ever done any tests on a 351 with a map sensor that Has to go through smog. I would like to get more torque out of my 94 truck ?
there should be smog legal parts for that application
I’d like to see the Holley efi vs a victor jr and a rpm air gap
I tested the RPM II vs RPM Air Gap
This engine is such a boat anchor. Over 3k for less than 100hp gains 😂 thats ridiculous. Todays Modern modular ford V6 engines make more than that on just actual bolt ons. Intake , throttle body, headers , exhaust and a tune. I wouldn't spend any money on this engine personally. Go with the coyote 💪🏻
Can you use that xe274hr cam with factory pistons? I'm assuming you would need rockers and springs with it regardless...?
yes with piston-you need springs, rockers are a good idea
Curious what the power differences are between carb and stock Efi on the 302, always ran one with a carb and dual plane intake.
dual plane carb is a lot better than stock H.O. EFI
@@richardholdener1727 cheaper too, procomp intake and distributor on a 302 swapped in a 240z back in high school.
@Jeff Kopis they do make carbs for mod motors they have for years and years. You dont see it alot but they do make em.
I bought a full lunatic balanced 408 stoker kit for my 351w. I had to cheap out on the pro comp 215 heads. Sent to machine shop for springs and a good look over. Used a Ford single plane high rise. Z 303 cam tried to stay all Ford I was dumb at the time. Any way my buddy ran a 79 sunbird with a 383. We both ran a glide with 4:56 gears. Stock suspension. Tubular k member on my 89 fox lx. 2007. They were all Chevy hardcore never even built a Ford. When they saw I had to do no block grinding for my rods to clear they were amazed. Stud girdle on mains and rockers. Very similar parts on both. They thought for sure my Windsor stood no chance. That Ford made no power crap was all I heard. Double the money later on my Ford even I was questioning my route I chose. We were on small tires. Foot braking no trans brake till later. Straight cut planetary for the glide killed my trans break budget and his. Any way we went to twiggs in Macon and Savannah before it closed and ran 6.10 all day no tuning no test. Once the mustang started to come around the economy fell out. I had to sell my engine for 5,000 to a cop in Atlanta. He said straight bolt up in his 91 he ran 9.80 in the quarter. These were N/A cars. Needless to say I noticed how much power and torque that 408 made which I'm not good on the cubes it was .40 over. It was a very impressive engine. Then I drove a built 347 and man the power band would kill that 383. Anyways just reminiscing the good ole day off 2005-07.
what happens when you add boost to the torque numbers at the bottom end that you lose naturally asperated with a freer flowing intake? Do you gain more or does the it still lag at the bottom compared to the more restrictive intake?
Stop thinking in terms of flow-the intake is not flow-its reflected waves that enhance cylinder filling (like boost) at specific engine speeds
What if I go from a 2 barrel to a 4 barrel intake on an otherwise stock setup? More likely to see a decent gain?
yes-about 25 hp
Was it Comp Cams that made some crappy black plastic upper manifold that bolted onto the stock lower ?? “ not for supercharger or nitrous !”
Hartman powerbox, then Comp bought them I think.
I have duplicated those results. An ebay systemax intake was worth 58 rwhp over a GT40 tubular.
Lies.
Not tuned ?
The car is ' 92 LX with a T-5. The long block combo at the time was 306 similar to the video. The cam was an E303 with 1.7s and AFR 165 58cc heads with shorty headers, off road H pipe, & electric fan.
With the unported GT-40 it made 274. With the Systemax it made 334rwhp.
I did port the GT 40 lower and ran that for awhile but it was a mess.
It was THIN in the runners and sucked alot of oil.
It made 316rwhp with that setup.
Trickflow used to make a complete top end kit for the SBF from 88-96.
I tested their top end kit
@@richardholdener1727 results/verdict?
What was the compression ratio of that test mule.
Richard, you achieved 261 HP on your stock 5.0 opposed to the factory-rated 225 HP. Is this due to the lack of the mass air system/intake, accessories, and the addition of headers?
yes
Are the Systemax intakes and heads still available? How about extrude honing?
A lot of intake stuff is based upon finding the right length to the runners, longer runners make peak torque lower and affect the rpm the engine makes power, shorter is vers visa, extrude honing doesn't change the tuning range or very little as the runners get bigger, the nice thing about extrude honing is getting to places that a traditional porter can't get to and fixing any casting flash and stuff in the runner itself, you can extrude hone a set of heads and intake till they start showing holes, and all it'll do is broaden the power around the peaks. So get the length right then hone them out.
What compression was this engine Richard?
I wish I.could.send you my ported upper and lower explore intake.. youd be very impressed I think. We'll find out here soon what it does to the rear tire.. couple.other things was.ported.as.well.. bone stock 142k mile bottem end explorer engine.. i did.change the cam.
With flat-tops and assuming 64cc heads right about 10 to 1
I've run lots and lots of ported and modded Cobra and Explorer intakes over the last few decades
Seemed like a lot of torque to lose at around 3500 rpm with the Holley
I remember back in the olden days [late 1990's ?] in the Summit or JEGS catalogs there was a "BOX" that would eliminate the runner's top section on OHV 5.0 and 5.8 EFI intakes.
I twould basically transform your stock 5.0 intake to a GM 1993 LT1 intake length and size wise, T/B remained at stock location.
Have you tested it before ? Have you seen in action ? Was it any good ?
If you haven't, would you consider testing one ? I always wondered if that thing was a sham or if it actually worked.
Downs, Cartech, Comp and TFS all made those Box uppers
@@richardholdener1727 was it any good ? Did you test any of it ? 🤔
The box intakes are mainly used for boosted applications.
@@Bird76Mojo76 I thought as much.👌🏻😊👍🏻 Way shorter travel for that additional air and acts as a surge box too.
I use a 1/2 inch spacer under my upper systemax intake for valve cover clearance. Will making the runners longer will that increase the torque a little bit?
Bobby4v - most likely the answer is yes, it would theoretically shift the usable power band down a little bit in the Rpm scale and bump your TQ if I’m not mistaken.
1/2 inch changes it very little
What kinda power do you think you'd be looking at with a 351 with gt40 heads and intake?
400 with a cam
How about a vid on a 9.5 deck. TFS box R vs. Vic and super vic. Both N.A. and boosted.
same thing happens NA and boosted
@@richardholdener1727 Did the box r make more power?
Have you done a 4.6 2V intake test between the Dorman, procomp/speed master, and Ford performance oe replacement intakes?
no not that test
Richard Holdener
I was just wondering since it’s hard to find a comparison between the three common intakes people swap into their 4.6 pi motors.
Great video, a lot of people still run and modify 5.0 mustang motors. Would have loved to have seen what a newer Holley Hi-Ram “LS” style intake is like in the same sort of tests.
stock bottom end 1985 5.0, added speedmaster heads, e303 cam. Power seems good up to about 5,000 RPM, then falls off(SOTP dyno). it is just my street cruiser, but of course, I'd like it to pull up to 5500-6000. does that mean better springs? thanks for any advice.
Don't know much about the heads you bought. 20 years ago I ported a set of E7TE heads and ran a set of beehive springs. 75mm tb and 70 mm mass air. E303 and ported Cobra intake. The 19lb/hr injectors were causing a problem above 5000 rpm. Used a Crane interceptor to find it. Also, I hope you ditched the factory epoxy core coil. On a mostly stock car with 3.73 rears, the engine used to nose over in first gear earlier than all other gears. An MSD coil fixed that. Factory coil hated revving high real fast.
Can you do a 5.0 from a Ford Explorer next?
I have run those
👍👍👍👍👍👍👍 x million
Can you do something with the tfs 205 11r Heads vs others on a 363
I second this! 👍
I've run those-they work very well
On an EFI engine like this, where the intake is "dry" before the injectors, would polishing the runners do any good?
porting them does-polishing them just makes them shiny inside-Extrude Hone porting does both
@@richardholdener1727 Is this because of the "boundary layer" to steal an aeronautical term? Basically the layer of air between the surface and the main column of air that is moving. Porting increases the main column of air and thus the volume of air for the same velocity. Maybe. Or maybe I should shut up and drink some more beer. Yes more beer.
@@richardholdener1727 I've had extrude honed intakes but they seem controversial, I'd love to see a test with and without to see if they actually help much.
weird request, I'm curious hw a gt40 intake would compare to a carbed edlebrock performer RPM airgap
gt-40 will make less
@@richardholdener1727 by a substantial ammount?
I love unsponsored real world testing. This is literal proof that I don't need new heads or intake to increase low end torque in my 5.0 equipped bronco. I'm going to spend that money on lower gearing!
👐
Have you done a test with the Holley hi ram on a 351w based mill?
not yet
Id be interested to see if there is a torque loss with the high ram on a stock bottom end 302.
Bobby4v yeah curious to see how much torque is sacrificed, pretty short runner length but +10 for aesthetics haha!
Does anyone know if a 92 f150 can be tuned if yes how?
Would love to see some 289 engines, 2bbl vs Hi Po vs Shelby
Jeff Kopis if you would have read what I posted I was wanting to the see 2 bbl 289 vs the Hi Po vs the Shelby. Not just him putting these same parts on a 289. It would kinda be like another other guys cause to many people forget about the 289
There is a HiPo 289 video up
Richard Holdener I went back through the videos and didn’t seem to find it
So, let me get this straight, one mod produces small gains but if you stack a bunch of mods on top of each other it produces big gains?? You don't say.
Hey, Richard. Where do you get your T shirts?
My wife makes most of them
Richard Holdener does she sell them?
Where were you 15-20 years ago when I was in the 5.0 game? Haha
doing this test (2003)-started back with my 1988 5.0L LX (original owner-still have it)
