Richard I'm 100% a CHEVY guy but I totally have to appreciate how awesome your work is. I mean talk about going above and beyond. Best "auto" channel on TH-cam hands down. Your dedication to the job is amazing.
Richard, you're going to love to hear this ... I hope ! I live in NZ, and have a 2001 Ford Falcon AU XR8 5.0 litre, 220kw(295hp). This engine came from the factory with Gt40p cylinder heads that were ported slightly to match the power of the GT40 Aluminium head, that went previously into the more expensive Tickord Version, Falcon. These engines were built at Tickford by 20 engine builders @ a rate of 20 per day. Other fantastic features were the --- factory fitted roller rockers, proper headers, 70mm throttle body, massaged upper and lower intake manifold, hot tested. Then, my Synergy V8 received a hand-engraved " Hand Built with Pride by.... J Neves (the guy that assembled it). MInes nearing 200,000 miles. I hereby declare this THE MOST POWERFULL straight off the production line 302/5.0 Ford pushrod V8 EVER ... Hope you enjoyed the read !!

I would love to see the same heads and same cam setups on the 351w short block just to compare how much you would actually gain with a "short block swap" I feel like a lot of guys would benefit from the knowledge of how much exactly you gain on the change in cubic inches alone all over the graph
Bascially, more power earlier, higher peak, and then the power would start dropping more a little sooner, if the 302 based engine couldnt work the head hard enough to show "choke."
I can tell you very accurate guess. You could count on around 450-460 ft/lbs and 415-425hp if a 351W short block with the same compression and camshaft were used. Hp would peak around 5500rpm

Older stuff of YOURS, but still a good watch and a nice relief from all the political talk. And I mean nothing bad in that as your info from then, is still just as real now. Over time you almost forget where we came from on heads. I still have my Windsor Sr from SuperShops in the garage. At the time, IF you couldn't step up to some highports it was about as good as it got for 1990. When 250cfm was great and 6500rpm of hyd roller was dreamy. Can you imagine telling some guy in 1990 that we'd be doing nearly 8000rpm with hyd rollers LOL. Esp the poor Chevy guys...... rem the helper springs on top of the lifters? Keep it coming, Richard!
Ive been digging through my old magazines. love seeing the info come back sir. i remember being 16-17 years old and digging through pick n pull windsor yard looking for a ford explorer engine. i ended up swapping in the trick flow stage 2 cam (.554 lift) as your recommendation from an article. funs times.
Two ways to look at the valve float issues with these heads: One is that they all provide insufficient valve spring pressure. Another is that the Comp XE series of cams push the boundaries of ramp velocity for street cams, requiring higher spring rates than most. All of these heads would work okay with a lot of aftermarket cams, including some of Comp's less-aggressive profiles. Choosing ramp velocities will always be a balancing act between increasing performance versus increased wear, noise, and valvetrain upgrade requirements. These days most folks are opting towards the higher ramp rates; as Richard suggested, head manufacturers mostly have followed the trend by increasing their spring rates. The takeaway is to match your springs to your cam maker's recommendation rather than settling for significantly lighter (or heavier) springs that happen to come on your heads. Economically, most of these heads can be purchased bare if a spring change will be required.
All of your data would be far easier to read in a spreadsheet than a text file like you have it. I've got plenty of extra time on my hands right now and would be happy to help compile it as such for future videos, even into a Google Sheets file that you could link in the description so that people could open rather than having to pause the video and transcribe.
Thank you thank you. I've always wondered what a set of gt40 heads were like compared to aftermarket. Would be neat to see what the iron gt40 heads would do on the same set up but with some porting and higher compression.
When are you going to do anything about the V10 Ford I would like to see some videos and there's probably a few other people that would like to see some videos on them too
@@tomstorino70 because it is a sweet engine except for the head bolts on the earlier years. I have owned 2 and never had a problem. A lot of horse power out of a 4.6L.
What does oil on the floor have to do with anything? BTW have you seen the V8 4.3 video he did? He could hardly keep it full of oil it was leaking so much.
PLEASE do a low budget head test. Ebay heads like NKB against flotek heads against basically everything under 1k/set and let's see what an average joe could do with a freshened shortblock and a good cam. All of these heads in this test minus the GT40s and the E7s are expensive as hell.
A lot of the head designs have been tweaked over the years as well as cam selection increase. I am talking about throwing a bunch of the NEW Ebay heads, Floteks (they have a new CNC version as well) and other heads that all are below 1k dollars/set (NKB and others) that are having a large impact on the scene where guys will go grab a short block out of a wrecking yard and throw H/C/I on it, maybe a little nitrous, and have some fun with it. The 7 heads that work test was also done on a lot of the harder to find heads that have gone up substantially in price Cite: World/RHS as well as were under 1200 not the 1K mark where you will find A LOT of these at. ALSO that test was not done on a wrecking yard engine but a DART block I believe and is NOWHERE near the same thing esp with pistons.
You should make a video getting the 302 to make max torque , lots of us guys with old 80s and 90s trucks and vans need more torque. Everyone always just says swap to 351.
I had a set of GT40 aluminum with the smaller combustion chambers with a Motorsport B cam. Car ran excellent. It was just a nice combo. Not the fastest but it did very well. Also holly systemax intake with 24lb injectors.
They had an episode of Engine Masters were they took a big 408 stroker and ran it with the little 165 AFR heads (they were starting there and comparing head sizes up to 220cc). The damn thing made 470 hp and 510 torque!!! As far as I was concerned that was the perfect combo for the street.
Amen! A good machine refresh and valve job, aftermarket springs if bigger cam, and real mild porting on the exhaust side to bring down that “knee” ridge... f’ers run real hard. And that iron will never let you down
@@xmo552 Has a C5 Automatic Trans, rebuild to a Super duty C4. 5000 stall converter, 410 gears, South side machine bar's, adjustable upper control arms. Competion adjustable shocks, 90/10 stuts on front. 50- 300 shot of NOS.
Regarding your question on spring pressure on HR cams. I came to the conclusion too much was better than too little. Less wear and chance of lifter failure from float was my conclusion. More power because no valve float. I went with a 450 lb/in rate spring. Its fine.
One option is to bolt on Cleveland heads. You just need to drill a water passage going to the intake. It might be difficult getting an intake. A Boss 302 is just a Windsor 302 with 4V Cleveland heads.
Perfect timing. Building myself a spare 305 at work with leftover parts. Got the block whole engine 50 bucks hydraulic roller block. Shooting for 400hp
I remember waiting for the next months magazine to hit the racks so I could buy it. This cylinder head tests series was the most informative things I remembered from any magazine back in the early 90s. I honestly didn't even know you were the one behind it. Thanks for all the time and effort you put into doing all the test and research. Just wondering, do they still call the dyno master himself " LL BRUEL J"
AFR builds good stuff but there are 2 better heads. One is the Yates nascar heads(BIG$). I don't think they're street legal. The other heads(king of ford Windsor street heads) are made by Jon Kasse. They are a canted valve design for better flow at high AND low lift. They made 499 horsepower on a stock 5.0 liter block with an intake and carb. Stock shortblock and i think the cam was too. These heads are called the P38 heads. I believe they sell for around 2400.00 for a pair which obviously isn't cheap but they ARE the best. If anyone has doubts about jon kasse, a quick Google search will show all the engine masters challenges he has won as well as lots of professional drag racing wins. He also custom builds the old school SOHC ford motors with brand new race parts for.......$55,000. He is a god. Anyway, I'm an old time fox body fan and Windsor lover and had to mention these excellent pieces.
Kaase heads don't make 499 hp on a stock 5.0L with a carb and intake-no heads do! Jon is a great guy and does amazing stuff-but he would be the first to tell you that you are misquoting the results of some test
Love what’s being done here lots of ideas. Would love you to do some straight sixes ie. Ford 300, chevy 290, dodge slanted etc. I’m a Ford guy and I have a few 300 L6 engines and would love to see what their potential is, and how they compare relative to each manufacturer. I’m certain that there’s a “small“ crowd of straight six fans out there that would love to see the same. Love the channel!Thanks.
@@richardholdener1727 I have a 84 Ford 300 industrial in my engine stand that I want to build and a 84 in a shed that needs to be built also, just in case you need one to monster build 💪🏻👍🏻🙏🏼
With the popularity of ported factory LS heads these days, it would be interesting to see a set of CNC’d set of the aluminum factory Ford heads compared.
Piecing together my dream list. Are the Trickflow wedge Heads the end all be all? Best of the best all rounder? Just wanting a fun, fast, cruiser/weekend car. Not hitting the drag strip.
HI, RICH.... Ever consider using a 2V cleveland head setup.? I say this asa good friend, Donnie S. did such a conversion... The biggest hurdle was (30 yrs. Ago) finding an ibmntake soecific. The result was a rynnin little SBF. PMoeak ho was (with a set of O'briens truckers headers) avout 420. Hust a thought.... God bless. BRIAN.
I own a mustang and yes these combos appeal to me greatly and Thank you for taking the time. My mustang is a twisty car. I want to build a vehicle for drag racing and that is my 05 Nissan Frontier. (It’s paid for). I also have seen a large following in the Nissan. VK series motor for drag racing. Really strong crank and block. I could use an LS and just be done with it but this VK56 is cheap, Titans and suvs have them. They are prevalent. Can you consider taking a look at it? You’ve done Honda’s and I think there’s a group that might open up to you. Big Thanks
Just saying, there is absolutely no way you could build the VK to rival power of an LS for cheaper as you say lol. Have you not seen the simple heads/cam LS motors that make well over 1000-1200 HP? That DOHC Nissan motor will take thousands of dollars more to be competitive in power production. Yes it is a capable engine, but there is a reason you see 100 LS builds at the drag strip for every 1 5.6 Nissan you might see running down the 1320 (or 660).
just subscribed to your channel...I have a lincoln mark 7 5.0 engine im building for my mustang. and the e7te heads have a plastic washer thats on the valves that sits on top of the valve seals its got a D5 on the plastic shim and i broke one and can't find it anywhere and nobody knows what it is either...do you know what im talking about?
Your videos are awesome and so informative. Makes me think of going through all the magazines back in the day before we had youtube to find the best combos. With this video I was kinda surprised you didn't have a set of trickflows....I have the trickflow trackheat 170 heads which were the most common used by renegade class back in the day along with the AFRs. I know there are tons of different heads but would have loved to have seen a set of trickflow in the mix. Anyhow, keep up the great videos. 👍 Just saw the other video you posted with twisted wedge. Nice to see, great data.
@@richardholdener1727 yeah thx, I updated my reply after watching video 2...lol Also, since I'm sure you have tested both, how do the trackheat 170s compare to the twisted wedge, I think mine are 61cc , can't remember it's been so long since I put them on...haha
@@richardholdener1727 oh, ok. Might want to check them out sometime if you ever address 302 heads, they were the most winning head type in nmra for I believe the renegade class. Even lists its history on Summit when you look them up. I just happened to be told about them at one of the many NMRA races at Bradenton I went to and after researching in magazines I found they and the AFR were the two top heads then. Anyhow, might want to check them out sometime. Thanks for your videos, makes life easier when considering different combinations.
I love Windsor content! Question for the field, and Richard if he sees: What "IRON" head would you choose for a 289 endurance motor? Limited to iron heads by class regulations.
It would good to know the flow from professionally ported factory heads. But hey, thank you Richard for your very considerable effort which produced a lot of good information!
David Vizard has a TH-cam where he said he did 2.02 and 1 6 valves in a e7te head with extensive port work and got 280cfm. It was him saying it. I don't think you can count on getting that number but many ported e7 heads are around 220 to 230 cfm or around some cleaned up gt40 iron heads.
I'd love to see a budget 302 setup --- Home ported GT40P heads, Explorer intake mani (if EFI), budget cam, 1.6:1 rockers, better valve springs, and some mid range headers (as exhaust flow for a 302 is rough).
@@richardholdener1727 I mean a low buck option that doesn't require additional changes. Hydro flat tappet from Speedway? They have a mild 219/233 that works with the 1.6:1s if I remember right
What this test affirms in my mind is why people would take a stock engine 5.0 Mustang in the early 00s and supercharge it to make power. That 264HR really is a great cam for how mild it is looking at the numbers.
Ive been looking into buying another of my original car, way back in the 80s… a 78 LTDII, that had a 351M, and had the option of a 400. Same for the next car, a 78 Cougar XR7 with a 351W. I was also scouting for a better engine/trans option, like a 351w, that doesnt require a lot of money, and I just discovered there is a Ford 534, late-50s thru early 70s, I think, that was used in big trucks and even used as a tank engine. Of course, I had to investigate this new thing. At something like 1300lbs, obviously its a MONSTER, and obv too big and heavy for most cars, like a mid-70s intermediate. Then I saw, in marine form, with dual turbos, it made a max of 400hp, so they already made a sort of performance version. Im curious if anyone has hotrodded one of those. Aside from the weight, it seems like it would be a natural to try beefing it up.
Ft/lbs is easier to say, but ft/lbs refers to linear torque, lb/ft refers to twisting torque. So lb/ft is what you should be saying-being an expert like you are!
I would love to see some of the budget ebay heads on a windsor. Plenty of info in sbc ebay heads, but none on ford's. There are heads for $550 on eBay. AT racing 175cc heads.
He's telling the truth! Spent last September in California and people thought I was weird wearing a T Shirt in 60 degree weather lol. Cold in California = warm to Wisconsinites
California has some of the coldest and hottest temperatures ever recorded in the US-all of California and all of Wisconsin are not the same temperature nor are the people the same-a T shirt in 60-degree weather is normal in any state
Sure, but I've never seen so many people complain about riding a bicycle outside while it's misty and 60⁰, they had hoodies and winter hats lol. To be fair, these were all people who spend 90% on the coast!
I noticed all the heads dropped off at 6000 rpm and that is due to the cam, manifold and carb being limited to there air flow that manifold can only flow 660cfm, I would like to have seen a single plane manifold and a 800cfm carb used, I believe the good heads would show way better numbers, It was not the valve springs fault.
Richard, Can you make an account on Rumble? I think you would be an amazing addition and this forum is now the enemy of free speech. I really don't want to miss any videos!!
Thank you Richard, I know a bunch of us Ford guys appreciate everything you do for us. Awesome information ,now all we have to do is pick a combo!

PLEASE do a low budget head test. Ebay heads like NKB against flotek heads against basically everything under 1k/set and let's see what an average joe could do with a freshened shortblock and a good cam. All of these heads in this test minus the GT40s and the E7s are expensive as hell.
this was done 10-15 years ago
A lot of the head designs have been tweaked over the years as well as cam selection increase. I am talking about throwing a bunch of the NEW Ebay heads, Floteks (they have a new CNC version as well) and other heads that all are below 1k dollars/set (NKB and others) that are having a large impact on the scene where guys will go grab a short block out of a wrecking yard and throw H/C/I on it, maybe a little nitrous, and have some fun with it.
The 7 heads that work test was also done on a lot of the harder to find heads that have gone up substantially in price Cite: World/RHS as well as were under 1200 not the 1K mark where you will find A LOT of these at. ALSO that test was not done on a wrecking yard engine but a DART block I believe and is NOWHERE near the same thing esp with pistons.
Rich!
I'm a little sad you didn't throw on the Ebay Chinesium heads alongside all these!
The Holley Systemax heads are chinesium.
@@zombieninjatedsmith1301
But they're not the ultra generic ebay heads. If it has holleys name on it it doesn't count.
Thanks. I have a few pairs or gt40s for my 351s. Kicking around Skip White though.
Love to see a E5TE vs E6TE vs E7TE shootout!!!!!!
Very cool 😎!!! I’m looking at one of these sets of heads for a F4TE 351w .
You should make a video getting the 302 to make max torque , lots of us guys with old 80s and 90s trucks and vans need more torque. Everyone always just says swap to 351.
I had a set of GT40 aluminum with the smaller combustion chambers with a Motorsport B cam. Car ran excellent. It was just a nice combo. Not the fastest but it did very well. Also holly systemax intake with 24lb injectors.
Definitely a proven combination on the streets back in the day!
Anyone know what whp would be on that set up?
They had an episode of Engine Masters were they took a big 408 stroker and ran it with the little 165 AFR heads (they were starting there and comparing head sizes up to 220cc). The damn thing made 470 hp and 510 torque!!! As far as I was concerned that was the perfect combo for the street.
On the 165s?
@@xmo552 Yep, probably the best general purpose Small Block engine I've seen. You could put it in anything and be happy.
AFR165 heads despite being the smaller option tend to flow very good for their size at reasonable lifts. The unsung hero
Got GT40 Ps on my Stang. Real Cobra intake, cobra computer, 24 lb injector's. It's out ran stang's with aluminum head's. It runs good for what it is
Amen! A good machine refresh and valve job, aftermarket springs if bigger cam, and real mild porting on the exhaust side to bring down that “knee” ridge... f’ers run real hard. And that iron will never let you down
What's the set up
@@xmo552 Has a C5 Automatic Trans, rebuild to a Super duty C4. 5000 stall converter, 410 gears, South side machine bar's, adjustable upper control arms. Competion adjustable shocks, 90/10 stuts on front. 50- 300 shot of NOS.
300 giggle juice horsies 💪😁
Regarding your question on spring pressure on HR cams.
I came to the conclusion too much was better than too little.
Less wear and chance of lifter failure from float was my conclusion.
More power because no valve float.
I went with a 450 lb/in rate spring. Its fine.
One option is to bolt on Cleveland heads. You just need to drill a water passage going to the intake. It might be difficult getting an intake.
A Boss 302 is just a Windsor 302 with 4V Cleveland heads.
You still have to plug the square water ports in the heads that flow from the Cleveland block.
Thank you for the hard work and data!
Perfect timing. Building myself a spare 305 at work with leftover parts. Got the block whole engine 50 bucks hydraulic roller block. Shooting for 400hp
Easy with carb.
Use the Joe Sherman tricks.
I remember waiting for the next months magazine to hit the racks so I could buy it. This cylinder head tests series was the most informative things I remembered from any magazine back in the early 90s. I honestly didn't even know you were the one behind it. Thanks for all the time and effort you put into doing all the test and research. Just wondering, do they still call the dyno master himself " LL BRUEL J"
we do
@@richardholdener1727 glad you've stuck with it so long, you don't know how many people you have helped with all your work . Thanks a lot.
AFR builds good stuff but there are 2 better heads. One is the Yates nascar heads(BIG$). I don't think they're street legal. The other heads(king of ford Windsor street heads) are made by Jon Kasse. They are a canted valve design for better flow at high AND low lift. They made 499 horsepower on a stock 5.0 liter block with an intake and carb. Stock shortblock and i think the cam was too. These heads are called the P38 heads. I believe they sell for around 2400.00 for a pair which obviously isn't cheap but they ARE the best. If anyone has doubts about jon kasse, a quick Google search will show all the engine masters challenges he has won as well as lots of professional drag racing wins. He also custom builds the old school SOHC ford motors with brand new race parts for.......$55,000. He is a god. Anyway, I'm an old time fox body fan and Windsor lover and had to mention these excellent pieces.
Kaase heads don't make 499 hp on a stock 5.0L with a carb and intake-no heads do! Jon is a great guy and does amazing stuff-but he would be the first to tell you that you are misquoting the results of some test
Man I know it was tough but I appreciate it. I feel like I owe you money at this point
thnx-it was a ton of work-but good data is valuable forever
Wow that's impressive! I could just hope that my 306 combination can be on the top of that chart. Great info and thanks for sharing with us Richard!
You bet!
another great 5.0 video, thanks and keep them coming
Wow, the AFRs were the CLEAR winner, with the Edelbrock, Canfield, Brodix, and Holley all vying for 2nd.

Love what’s being done here lots of ideas. Would love you to do some straight sixes ie. Ford 300, chevy 290, dodge slanted etc. I’m a Ford guy and I have a few 300 L6 engines and would love to see what their potential is, and how they compare relative to each manufacturer. I’m certain that there’s a “small“ crowd of straight six fans out there that would love to see the same. Love the channel!Thanks.

With the popularity of ported factory LS heads these days, it would be interesting to see a set of CNC’d set of the aluminum factory Ford heads compared.
Ford never offered alum factory heads on the 5.0L

Incredible amount of work and your time thank you
My pleasure!
I’m running AFR 185s on my 89 LX. I don’t have any complaints.
Piecing together my dream list. Are the Trickflow wedge Heads the end all be all? Best of the best all rounder? Just wanting a fun, fast, cruiser/weekend car. Not hitting the drag strip.
there is no end all be all-but TFS heads are good
Awesome! Old fuelie cylinder head shootout 👊 Thanks for this series richard, you’re a legend Bro!
HI, RICH....
Ever consider using a 2V cleveland head setup.?
I say this asa good friend, Donnie S. did such a conversion...
The biggest hurdle was (30 yrs. Ago) finding an ibmntake soecific.
The result was a rynnin little SBF.
PMoeak ho was (with a set of O'briens truckers headers) avout 420.
Hust a thought....
God bless.
BRIAN.
Thanks Richard, nice work and excellent presentation 👍 wish I could hit like more than once.
I own a mustang and yes these combos appeal to me greatly and Thank you for taking the time. My mustang is a twisty car. I want to build a vehicle for drag racing and that is my 05 Nissan Frontier. (It’s paid for). I also have seen a large following in the Nissan. VK series motor for drag racing. Really strong crank and block. I could use an LS and just be done with it but this VK56 is cheap, Titans and suvs have them. They are prevalent. Can you consider taking a look at it? You’ve done Honda’s and I think there’s a group that might open up to you.
Big Thanks
Just saying, there is absolutely no way you could build the VK to rival power of an LS for cheaper as you say lol. Have you not seen the simple heads/cam LS motors that make well over 1000-1200 HP? That DOHC Nissan motor will take thousands of dollars more to be competitive in power production. Yes it is a capable engine, but there is a reason you see 100 LS builds at the drag strip for every 1 5.6 Nissan you might see running down the 1320 (or 660).
USA aftermarket heads are so good. But CNC machined GT49Ps are 215 to 22
Another great one Richard, thanks.
I have a set of the GT 40P's a set of J302 heads as well. Always wanted either the Canfields or the AFR's but never enough $

@@unicornsteaks6769 U.S. ............Very informative, something to look in to ?????????
just subscribed to your channel...I have a lincoln mark 7 5.0 engine im building for my mustang. and the e7te heads have a plastic washer thats on the valves that sits on top of the valve seals its got a D5 on the plastic shim and i broke one and can't find it anywhere and nobody knows what it is either...do you know what im talking about?
YOU DON'T NEED IT IF IT SITS ON TOP OF THE SEAL
@richardholdener1727 that's what I was thinking is it something from the assembly line to hold the valve in until the spring is installed
@richardholdener1727 and thx you for your fast response
Why no TFS Twisted Wedge? Those were among the top back in the day, and respond very well to porting.
THOSE WERE TESTED, IN ANOTHER GROUP (THERE ARE 4)
@@richardholdener1727 Thanks for enlightening me, and for your hard work!
Your videos are awesome and so informative. Makes me think of going through all the magazines back in the day before we had youtube to find the best combos.
With this video I was kinda surprised you didn't have a set of trickflows....I have the trickflow trackheat 170 heads which were the most common used by renegade class back in the day along with the AFRs. I know there are tons of different heads but would have loved to have seen a set of trickflow in the mix.
Anyhow, keep up the great videos. 👍
Just saw the other video you posted with twisted wedge. Nice to see, great data.
check out part 2 of the head test-the tfs heads are there
@@richardholdener1727 yeah thx, I updated my reply after watching video 2...lol
Also, since I'm sure you have tested both, how do the trackheat 170s compare to the twisted wedge, I think mine are 61cc , can't remember it's been so long since I put them on...haha
not sure on those exact heads
@@richardholdener1727 oh, ok. Might want to check them out sometime if you ever address 302 heads, they were the most winning head type in nmra for I believe the renegade class. Even lists its history on Summit when you look them up. I just happened to be told about them at one of the many NMRA races at Bradenton I went to and after researching in magazines I found they and the AFR were the two top heads then. Anyhow, might want to check them out sometime.
Thanks for your videos, makes life easier when considering different combinations.
I love Windsor content!
Question for the field, and Richard if he sees:
What "IRON" head would you choose for a 289 endurance motor? Limited to iron heads by class regulations.
Richard sees every comment-the dart windsor maybe? or iron TFS high port
@@richardholdener1727 Thank you!
Heard great things about the high ports, and the Dart 180cc Iron Eagles look to flow >220 @0.500
It would good to know the flow from professionally ported factory heads. But hey, thank you Richard for your very considerable effort which produced a lot of good information!
David Vizard has a TH-cam where he said he did 2.02 and 1 6 valves in a e7te head with extensive port work and got 280cfm. It was him saying it. I don't think you can count on getting that number but many ported e7 heads are around 220 to 230 cfm or around some cleaned up gt40 iron heads.
I'd love to see a budget 302 setup --- Home ported GT40P heads, Explorer intake mani (if EFI), budget cam, 1.6:1 rockers, better valve springs, and some mid range headers (as exhaust flow for a 302 is rough).
what is a budget cam?
@@richardholdener1727 I mean a low buck option that doesn't require additional changes. Hydro flat tappet from Speedway? They have a mild 219/233 that works with the 1.6:1s if I remember right
Those afr heads are pretty wicked. I need those. 90 hp gain ???
Use the 351w 1969s too even the 302 trucks 1969 heads
Awesome video man, just missing a trick flow head
see part 2
thank you so much for your time! rich
Thank You Richard! Great data again!!!
I think you should show all the work that goes into your videos.
it would be hours long
Excellent! Loved this back in the day. Looking forward to the series. I still run the old school GT40-Y’s lol
What this test affirms in my mind is why people would take a stock engine 5.0 Mustang in the early 00s and supercharge it to make power. That 264HR really is a great cam for how mild it is looking at the numbers.
Now I want to pull my aluminum gt40 for some afrs and a 274 cam of course.
Ive been looking into buying another of my original car, way back in the 80s… a 78 LTDII, that had a 351M, and had the option of a 400. Same for the next car, a 78 Cougar XR7 with a 351W. I was also scouting for a better engine/trans option, like a 351w, that doesnt require a lot of money, and I just discovered there is a Ford 534, late-50s thru early 70s, I think, that was used in big trucks and even used as a tank engine. Of course, I had to investigate this new thing.
At something like 1300lbs, obviously its a MONSTER, and obv too big and heavy for most cars, like a mid-70s intermediate. Then I saw, in marine form, with dual turbos, it made a max of 400hp, so they already made a sort of performance version. Im curious if anyone has hotrodded one of those. Aside from the weight, it seems like it would be a natural to try beefing it up.
Those afr heads are impress, I have edelbrock performer on my 347, looking at 11r for my next build
Thank you Richard. Isn't this the same test as MM&FF magazine did years ago ? I still have all the magazine's. Nice to see it in video form now.
Ft/lbs is easier to say, but ft/lbs refers to linear torque, lb/ft refers to twisting torque. So lb/ft is what you should be saying-being an expert like you are!
Do a mopar small block next please i wanna see all the aftermarket heads available please 🙏
I would love to see some of the budget ebay heads on a windsor.
Plenty of info in sbc ebay heads, but none on ford's.
There are heads for $550 on eBay. AT racing 175cc heads.

He's telling the truth! Spent last September in California and people thought I was weird wearing a T Shirt in 60 degree weather lol. Cold in California = warm to Wisconsinites
California has some of the coldest and hottest temperatures ever recorded in the US-all of California and all of Wisconsin are not the same temperature nor are the people the same-a T shirt in 60-degree weather is normal in any state
Sure, but I've never seen so many people complain about riding a bicycle outside while it's misty and 60⁰, they had hoodies and winter hats lol. To be fair, these were all people who spend 90% on the coast!
Thanks for the sbf content definitely need more ford videos
I noticed all the heads dropped off at 6000 rpm and that is due to the cam, manifold and carb being limited to there air flow that manifold can only flow 660cfm, I would like to have seen a single plane manifold and a 800cfm carb used, I believe the good heads would show way better numbers, It was not the valve springs fault.
VALVE FLOAT IS THE SPRING/CAM'S FAULT
