LOW-BUCK 302 FORD HEAD UPGRADE
HTML-код
- Опубликовано: 10 июл 2020
- WHAT'S IT WORTH? FULL DYNO RESULTS. BONUS TEST-FOUR DIFFERENT 302 INTAKES. Check out this test where I compared stock 5.0L heads to GT40P to AFR 165 heads. How much power do the junkyard P heads add? What happens when you upgrade further to after market heads like the AFRs (lot of good 5.0L heads out there). What about intakes? I compared four Edelbrock intakes, the Performer 289, the RPM Air Gap, the Torker II and the Victor Jr. How does your fasvorite stack up?

I could watch 302-based videos all day. Love the little 5L.
I like the 289 even better!
Back in the day, I did too. I really didn’t understand all the hub-bub with FE engines. Go look for the 68’ 427 Holman-Moody Mustang.
That video can do more to describe the exhilaration than my words ever could.
But, a 347 is a really good compromise....
Sounds awesome brother I have a 1996 Ford F150 with a 5.0L (302) Windsor V8 with 209,000 miles and still going strong.
CJ Colvin just bought a 00 explorer for a ranger swap, got it for 450 bucks and 285k, still running and driving just fine!
@@DylanC828 Awesome brother.
Richard- there is no need to apologize, we're getting information here that would literally cost thousands to obtain on our own. Don't be so hard on yourself.
Agreed, I was both surprised and exited when I found this channel dueto the content!
@@LandonRoy-cv9rt Yes. There is so much wealth of info in this channel.
Amen thank you
Well the reason he has such success and knowledge is due to how particular he is so i say YES! The apology is welcomed
Richard you should put this all into a book or sell research reports for gear nuts
Keep the FORD stuff coming Rich! Us Ford guys know who to come to for the right info!!
Damn dude, don't ever apologize. What you do and present is WAY more than expected.
Thank you!
Being a small block chevy guy, Im always amazed and pleased with the power potential of the sbf.
Even without the pictures you are still saving people thousands on what works and what does not.
Who cares about the pictures? Your testing and knowledge are why I am here. Cheers!
I am a Test Engineer and your scientific approach to testing and data analysis is 2nd to none. I am building a low-buck 5.0 and your evaluations keep me from making costly mistakes. Thanks for doing these excellent videos on the 5.0.
happy to help
Getting to see the graphs is really fascinating. It's neat to see just how a head swap can change power and how a cam swap changes where the power is. Excellent work
I like these tests. Gets rid of the guess work and makes choosing parts easy 🍺👍👍
I definitely don’t care about the photos!!!!! Your knowledge is the most valuable part of this channel!!!!
You, Sir, are a BEAST!!!!!! I can file rings, but would not have the patience to do all the testing you do. Great info.
Just bought a obs ford f150 5.0
Starting to look at videos to add some power.
Just as a project. And now I’m here. Great videos. Love the information. I’m sure by now the video production value has gotten a lot better.
Thank you 🙌🏼
Awesome data Richard, we would never be able to source the information you can supply in a 15 min video
Love seeing how well a great engineered head works! Great info, as usual!
Great video! You had all the pertinent information and visual aids needed, and presented it without taking all day.
Good stuff Richard! I can't tell you how many times I have watched your videos. Can't get enough of the 302 and 347. I also love the FE, but not many people have one of those. I have a 302, BP 347 and a 390 from Team C. Keep up the good work.
Recently found this guys vids over here in the UK and good straight to the point information , with no brand pushing
Video is perfectly fine, it helped me quite a bit. Richard, I remember reading your stuff in MM&FF with Jim, Evan & Bernie articles. I will always read everything you post and take it all in.
Awesome video!! Finally a good video and info on a 5.0/306. I'm just glad to see this combo made close to 400hp and torque.
This is an awesome test because you did all the engineering log work to get great outcome. Thanks Richard
Richard, you have to be the hardest working guy on RUclips! Thanks for the great content!
I remember those mm&ff articles when I was building my engine in my 84 gt
I had a set of 69 Windsor heads home ported a duel plane stealth intake with a XE274 cam and a 650 dp and a recurved dist.
Had a lot of fun on the street and surprised a lot of people. 3.73 gears and sticky tires
I miss those days 😕
I believe everyone has gotten what they came for without the pictures fella
Richard, pics or not, a great, informative video.
Don't go knocking yourself down Richard, It's very good information you give out, No one else on here gives more information then you do, Keep up the good work 👍
Thanks so much for doing this!
I'm an avid foxbody Mustang fan and have attempted a couple different engine combinations, so this was super informative!
I made a comment on this on one of your other videos a few days ago, I guess it just so happened that you came up with this now so my questions are answered. Glad to know my truck is making quite a bit more power and it's not the placebo effect lying to me.
Thanks for the info it really helps picking out components great work you do Richard.
I had AFR 165 heads with an E303 cam. Huge seat of the pants difference. The rockers were always really noisy at high rpms. This might explain that. I also broke 2 ARP rocker studs on the same rocker. Got tired of studs breaking so I sold the heads. I bought the knock off 190 heads and sent them to get ported and stronger springs. Never had the problem again.
Thank you for all the time you put into this work. I really enjoy watching your videos. I love the aahhaa moments like this that explain some of the problems I've had.
For me it didn't matter that you were missing photos. You always provide great info. My regret with my Ford 306 putting on the afr 165 instead of the 185. After hearing you say the 185 does not kill tq down low. Keep up the great content.
Man I just love the little 302.. always have. Solid presentation.. we got great info.
Thank you for the great information, no one has great data on the gt40p head upgrade and this really helped. I'm building an f100, and will probably copy this to some extent, but with a weiand intake and a normal holley 650
Thanks Richard! Just what I was looking for! That is, until I saw your 351 video, lol. Made it hard to decide between the two.
Great video I like seeing what the different parts will do in H.P. and Torque.
I appreciate that you did all the legg work for us to help make a decision 👍
Thank you for your work. It’s helped a lot with my 93 fox and my 95 impala
Your the man Richard! This is the one I’ve been wanting to see! The good ol Gt40s 👍🏻. This kinda lets me know my HP 🤓
Thanks so much for the data bro I think u did very well. I love these fords keep up the good work.
You are doing a great job and yo don t have to apologize.We got all the info we need.
You only think you did wrong it was excellent as always. Tons of suggestions, knowledge and ideas. Thanks Richard
Great videos Richard. I'm learning a ton of info
Thanks for what you do have, and am willing to share. Most people that have knowledge forget to pass it along. Awesome test like always. I have actually had that same set up with gt40p heads with that cam but ran an edelbrock 1406 for years in a bronco and loved it. Always wanted to know what power it was at. Thanks again.
I've been looking for a mild gt40p dyno graph for awhile now, Thank you
I appreciate all your. Work and love your videos. I watch all your. Stuff
Thank you Richard! I have been deliberating on dropping a 5.0 in a Dodge Ram 50 or into a Mazda RX-7. Both of these vehicles have bad engines. Either way, your well done video will help me to make some decent horsepower in whatever platform I decide to go with. Now the hard part will be to make up my mind as to which one gets the V-8! LOL! Who needs pictures when you explain all your research and methods so thoroughly!
Thanks for all the hard WORK.
Great little engines, amazing what they’re capable of with 300 cubes. 👍🏻
4" is the "correct" size bore!
Hey Richard, great comparison, shows dual planes and factory heads best for mild to medium street motors with up to 230@ 0.050” duration cams. Single plain for bigger heads and cams… it’s a no brainer really!!
Always interesting stuff.. keep it coming!
Jon from down under
Your videos show us so much. It’s crazy. When I have the $$ I’m definitely going to an AFR with the 274cam. Currently running comp210s and the xe270 cam. Some day haha
I am building a 302 as we speak , so now I know exactly what to do . Thanks for the video. Brilliant
Yes sir spend that money for the AFR and a air gap
Glad I could help
air and air
I love all of your videos. Thank you for this one.
I love a photo of a tight timing chain.
Love the low buck videos. Keep up the good work!
Dude, your data is the gold... don't apologize over a few photos... if we really need to see what it looks like, there are thousand of pictures to look up... independent dyno testing results are what's rare and hard to find....
Can't wait for the sbf cylinder head compare video. Getting ready to buy a set.
You and Matt Happel put out the best hot rod info on the internet
Matt does good stuff over there
I have many 6.9x slips with a exploder long block and a small shot. I love these heads because they are so cheap and thats all alot of us budget guys had for a long time. Its been years now so I don't remember times exactly but from just a minor bowl blend and exhaust clean up was good for a few numbers. The stock spring in the e7 head isn't horrible, but the exploder heads have really bad springs.
This is one of those things that even happens occasionally to the top dogs in the business. I don’t mean to suggest that you’re a dog Sir Richard, but you are definitely the best at what you do. The test results clearly illustrates the performance advantages that are easily available without getting too radical with the combination. Nicely done AGAIN !
And by the way, you did something that most guys would rather die before doing...you publicly accepted full responsibility for the minor mistake that you made. It’s a sign of impeccable integrity and that’s a trait that is in short supply nowadays.
definitely not a top dog-just a junkyard dog
Good show! Keep the Ford stuff coming!
Thanks for all the hard work you put into your videos! I’m a Ford fan and all this info is priceless !
You bet!
MMFF Ultimate Guide to Cylinder Heads - tested so many tests it had to be done in several issues. I remember it well, and probably still have the issues in my archives. That was an epic effort! I struggled with data overload for months before deciding on the AFR185's. Then got hung up on whether I should go ahead and build a 392 from one of the articles in one of the issues. I'm not sure if you saved me money or cost me a ton!!! LOL!
That was a magnificent series of testing and data. It was absolutely revolutionary at the time. I'd never seen anything like it, despite all enthusiasts having NEEDED it for at least 10 years, by then.
I am personally more concerned with the hard numbers and dyno results. We all know what the different heads and intakes look like. You don't need to apologize for leaving out in what I consider insignificant details. Great content btw.
Super information, Keep up the good work Richard,
thanks for the info
Ive got a 306 with Fcam and with GT40p heads also have changed the valve springs i put the TFS spring kit on the heads have 2 choices of intakes performer RPM or summit intake also have the msd dist and 6al with mac long tubes dont have the motor in the car yet it will be carbuated
My '79 F-150 has a 302 and I'm pulling it to rebuild. I'll be doing it myself because I want to learn about everything. I'm glad the dual plane intake is better. But it'll be a slow process to rebuild, but it'll still have a stock bottom end just with new bearings, but then I have choices of heads. I thought about an RV cam. Might still do that. But thanks for your info.
Thank you Thank You Thank You much appreciated being a 5.0 owner great real world info that can be applied!
Great info - as always.
I would like to see a straight up comparison between the stock '87-'93 5.0 HO EFI intake & heads & swap them for the Explorer heads & intake - with a cam/spring upgrade, of course.
I snagged the "P" heads, intake & 65mm TB for $150 off a Mountaineer from the local JY to put on my daily driver '89 GT. It has a valve tap & if I have to take it apart anyway, figured why not?
That was one hell of a comparison, thank you.
Love the 8200 deck Fords ,I ran one back in the day forged pistons , lunati roller cam Canfield high port heads , rpm manifold , demon carb long tubes mad ignition and distributor , and a little spray . that combo i n a 2800 lb fox produced mid 10 second slips and a really fast street car .
Great video work , I havent owned a 302 in almost 20 years but still wondering how to make them run better and seeing all my old HP mistakes. Biggest one i see is the valve springs and a commitment to my original torker 289 . it ran so good on my stock 66 289 GT back in 1971. I ran a set of 351 heads off a Mach 1 on a 302 for my last build , never broke on me in 20 years of racing and street use. except one day floated a valve and had to replace it , Biggest change in Et came from a set of flowmaster over axle 2.5 inch exhaust , picked up 5 mph in the quarter.
Just remembered one super cheap thing to prolong engine life is I glued a speaker magnet to the outside of the oil pan , after pulling the pan a year after building the motor to check out a noise which was the fuel pump luckily,, the inside of the magnet area in the pan had a layer of fine dust , most likely shavings from the cylinder walls and prevented them from going thru the oil pump , cheap protection.
"Back then" lol this man was running tests on fred flintstones whip changing shoes and seating positions hahaha.
302's are my favorite car engines. (Chevrolet DZ's, too.) So I'm *really* interested to find out about that big, detailed MM&FF test you mentioned.
This pair of tests was interesting, too. The big surprise for me was how well the RPM 289 did. In fact, that whole test series seems to have had a reasonably stout 302 running.
Not an RPM.
Just a Performer 289.
Can’t wait for you to release the results of the giant head testing you did for MM & FF’s!!!!
I will-lots of work
Is that video posted?
I have some World/Roush heads. I wonder what to expect from them. I'd like to run them as efi on an '88 GT.
It’s a multi part series now
Loving your videos!
One thing. The average guy grabbing gt40s knows by now stock springs are weak in explorer trim.
Dyno God should never apologize. Come on , your production is better than 3/4 of Videos on tube, besides its information and knowledge we are after
When I was younger, it was all about the cam, Want more power? get a bigger cam. Always flat lifters btw. When the aluminum heads came on the market, it was hard to believe how much power difference a head could make. They were quite expensive though. But its hard to believe that a head swap was worth nearly 100 horsepower given everything else was equal.
Now a days, for a mid RPM truck engine, it can make GOOD power AND have a smooth idle with aftermarket heads and a roller cam
Im running a mild 327 stock bore stroked 302. Gt40p heads. I just cleaned up the intake side of the heads and a very mild touchup of the bowl area and exhaust. Upgraded the springs added a comp roller, new pushrods 1.6 rr. Trackheat intake, 70mm tb. Its not no hotrod but makes for a great little street motor. Faster than i want to go. Great torque as well. Ive never dyno'd it but im thinking somewhere between 300 and 320 horse. Still gets respectable gas mileage on the hwy with 373s
Not a problem for me. If you hadn't mentioned lacking the photos, I wouldn't have complained. The most important thing is the dyno graphs.
Sure would be nice to see the power curve down to around 2k rpm. Looked like the single plane jumped up quite a bit above the dual plane below 3,000.
For some reason GM used a single plane intake on their HT (high torque) 4100 Cadillac Engine...
BTW, the 4100 gets a bad rap, but I really like them, for something that size.
The engineers really broke out of the mold when they designed that engine. If you haven't already, you should take one apart and check it out sometime.
richard, enjoy your vids.. really love your tshirt here!
I’d love to see a comparison using the early Ford 351w C9OE /D0OE heads. Years ago, they were the “go to” for inexpensive street builds.
That's basically a fat spark plug GT40 head.
Same ports, chambers, etc.
Let me know what you think it’ll do!! Thanks for this valuable info!!
Richard we absolutely love your dedication regardless of how the vid appears. Your enthusiasm for all types of engines is quite refreshing especially since the ls swap the world stuff is everywhere.
No apologies needed sir. Your AWSOME
Nothing wrong with this, you still can get the point👍
Dont be sorry, i love this info. Its hard to find reliabale info on this stuff
I'm still trying to decide what to put under the hood of my late uncles 71 Pinto.
My cousin has the 72 my uncle put a Chevy driveline in, back then.
Don't sweat the small stuff....very informative video.
P-heads are decent...upgraded springs, port and polish, and milled .020" yielded me 65HP on my setup years ago.
93Cobra, what header are you using on your 302?
@@israelfranco5332 I had a custom set of full lengths....1 5/8 primaries.
I'm building this same combo right now for a Ranger, liked seeing what the Explorer gt40p head did for a bit more power than stock e7's. I love the low buck, practical builds that don't break the bank. Great job.👍
50Tussin. RUclips. Do it.
Thanks for your time, Great info!!!
The data is what's important, and you produced / showed that. Kudos. What your data tells me that unless you're one wanting to run around at 6K rpm, the P heads are fine.....and the spendy aluminum ones are not worth it for the extra 30-40 horsepower (at least to me).
Awesome content, one of my favorite videos you've done so far.
Richard recommended an xe274 cam for my 302 (ofc lol) however I decided to go another direction for now. I bought a running and driving 00 explorer for 450 bucks, and I’m rebuilding the motor for a ranger swap. I’m trying to stay on the cheap for now until I can get back to work after this corona crap, then I’ll go for the gold. For now though, I just want it to run and drive while keeping my 5 speed 4x4. With the explorer motor, I can do a valve spring upgrade, HO cam swap, and 1.7 roller rockers. That combo will let me safely rev higher (approximately 6500), hold power throughout the rpm range, and give me a total valve lift of .472. Couple that with a bit of a port job, I’ll be able to flow an approximate 215 cfm intake, and 147 cfm exhaust. Math tells me that will net 305hp at the flywheel, not bad for under 1k. Later on when I have the money, My parts list includes upgrading to trick flow 11r 190cc heads, and a custom grind cam allowing for .550 lift intake, .575 lift exhaust with a 112 lsa netting a very healthy 470hp at the crank (if my math serves me right) and a very streetable rpm range (keep in mind this is for a 4x4 truck) of 2700-6300. My biggest question really is if I should buy those heads bare when the time comes or if they actually ship with quality valves and springs? Does anyone have experience with 11r heads?
At almost one and a half horsepower per cubic inch, my truck hauling fruit to the farmers market would get there in time. Excellent testing and time spent.
Have had 7 Mustangs with 302’s....love the V8 and compact size (compared to the new DOHC 302’s). Best 302, I have is Balanced, Blueprinted, Forged Pistons, Ported GT40p heads, Explorer GT40 intake, bigger throttle body, GT40p shorty headers. Has a E303 cam...a little lopey for the AOD (not enough LSA for Fuel Injection)....really strong above idle speed. Love it, will never sell it.
Great content regardless of photos. I was thinking a video on detonation and what promotes detonation and what starves it off, more on the mechanical side, like do wide lobe centres help in running higher boost, how does squish affect detonation on the limits. Maybe running the test on low octane fuel and exploring pushing the detonation envelope on a turbo engine.
Who in their right mind would intentionally detonate an engine over and over? You realize it's literally like hitting your piston with a sledgehammer don't you. Perfect way to put piston skirts in you oil pan.
When mustang 5.0 magazine took out babe of the month I quit reading them lol.
I would like to see best low buck set up like, gt40 heads, explorer intake, 65mm tb, 36lb injectors N/A or b303 vs e303 camshaft, etc..
