I knew a kid that did this when we were in school for engine building. He used three-cylinder heads. One was just the center two cylinders and the other two heads consisted of the front version of the cylinders in the rear two cylinders. These were all cut down and then machined to get the spacing as equal as possible on the Ford block. Similarly he blocked off the water passages all of the head but he machined a hole through what he blocked off and then had a bung that was welded to the block off on the other side of the matching head which then press fit into the hole drilled of the opposite head. That way once the head was all machined and pressed together for final welding assembly coolant could flow without extra external lines. As for his intake he did something similar to you he bought a few carbureted intakes and chopped them up he did three two-barrel Holly carburetors. And he did a similar header style set up as you as well chopping up existing cheap headers. Overall it worked out really well. And if I remember correctly was making far over 350 horsepower. It was a very labor-intensive build but overall very unique and rewarding. The entire engine building school was involved and it was a lot of fun to see it take shape.

If the answer to A is yes, what's the benefit of an LS head that makes it preferable to an aftermarket high performance Ford 300 head, or a custom made & modified Ford Cleveland head fit to a 300? - Glad you asked! I could write an entire thesis as to why an LS design is preferred...but it's not that simple. To question why going through the trouble of making this head, you have to better understand how the Ford 300 or old American inline 6's work. The Ford 300's were designed for the sake of manufacturing, and ease of cost. You run into problems like un-even/poor distribution of airflow, fueling, and probably the biggest elephant in the room, and the bane of all American 6's is their..."Reverse Flow Head" . At this point you might be asking why bring up this fact? While the aftermarket heads that are currently available for the 300 come in aluminum variants, and are of high quality. Still the achilles heel of aftermarket 6 heads is that they still use a similar form of reverse flow. The LS head isn't the most magical part, it's taking the LS pieces, and turning it into a more efficient "Crossflow Head" design. The Crossflow fixes the biggest problem of the 6's, which actually is "Heat" . Why choose an LS head over a modified Cleveland? - This one is preference, while you could weld up a Ford head off their V8's which'll work just fine, but the LS flows better and is more efficient in stock form.
Did this with Cleveland heads a few years back after seeing someone else's old build doing it. Got curious and had to try it. Took a ton of time but the gains getting away from that log head were well worth it. It felt like no other 300 I've ever been around. As much as I hate Chevy, I'm stoked to see this. Always good seeing another Frankenstein style builder.

You sir are a dam Hot rodder of the first order. NEVER NEVER NEVER let any of the trolls bother you. 99 percent of of these guys can’t tie their own shoes. Looking forward to more updates please.
My hat off to the fabricator. I suspect that critter will breathe! I remember a magazine article or two back in the late 80s of the racer doing the same thing with iron Cleveland heads. Made for a formidable drag car.
I wish there was a company that sold modified LS heads and head packages for 302/351w and 240/300 I6s. 706/862 heads are certainly cheap enough, I would guess they could set up all the tooling and create jigs that would allow them to output quite a few of them in a working day and make a decent profit off of it.
I've seen Ford's in Chevy's and Chevy's in Ford's. Mostly LS's in Fox bodies but this should prove to be very interesting. I'm betting 400 hp and a vented block at 5000 rpm.
The reason to use a Chevy LS head instead of a Ford Cleveland head is that the valve sequencing on the LS is the same as the standard 300 straight 6 head. Therefore you can still use the standard 300 cams. If you use the Ford Cleveland head, the valve sequence is exactly wrong, so you have to pay to have a custom-grind cam. made. Standard cam vs. custom ($$$) grind cam. Plus, the LS heads can be bought from a salvage yard or GM dealership, whereas an aluminum Ford Cleveland head cost mucho dinero more when bought from a speed shop or distributor. I know its sacrilege to put a Chevy head on a Ford (or vice versa) but the relative ease and the economics involved make the head choice an easy one.
Im a ford but have messed with sbc and bbc engines too but first time I worked on an LS it felt more like a sbf then a chevy. Even the distributor conversion uses a ford distributor and mounts at front of block.
The 300 has 4.4" spacing as well instead of 4.38" like a SBF/335 engine. I have seen LS heads work on a SBF though so I guess that isn't a total deal breaker.
Man that is awesome you are building one of the coolest 300 I've seen in a long time a lot of ideas you're incorporating I've heard kicked around before but never actually done or certainly not done together
392 style Hemi heads also have a close enough bore spacing to do this and there are lots of aftermarket high flow units around. If you bore .040 you can offset cylinders to match head centres. You can use a custom copper gasket to keep the gasket lined up with the bores.
@@mctigmctiggy1475 Some of the franken Cleveland 300-6s used 3 peice pushrods to get the monkey motion around the ports. Original 392 hemis have pushrods.

I have a 300 project as well as a pair of LS heads from a truck motor that spun a bearing. I am seriously considering doing this same operation. I have a 350amp TIG here in my shop so welding it is not an issue.
I love how this video has over 8k views and none of the big names in performance have come up with a cross flow cyl head for the Ford 300 yet. Or even a performance cyl head. Clearly there's an interest. You hear stories of people who've built their own and how crazy powerful they were. I honestly think there's a market for it...
I have been saying for years that there are willing buyers for this. Lotta inline 6 trucks out there with no real performance potential because the stock 240 heads can only do so much for one. I am a BBF guy, and people used to say there wasn't enough takers, but now they sell over 30 different cylinder heads for them. There are lots of Ford fans and just plain 300 six fans that would buy an aluminum cross flow head. Make some forged stroker cranks while we're at it!
I'm glad i fast forwarded to the end to find out that this guy was still talking with the camera still aimed at the same stuff as in the beginning of the video. It'll probably take him another 10 videos before we get to see this thing running.
6 in a row. Love the 300 6. I was sure this was all bull. Till I listened to you till the end. I can not wait to see what you do with it. How it acts. The surprises the short comings. Dam I wish I knew you bro.
It’s a monster! Due to the lack of after market parts for these truck in their prime I can’t wait to see where this goes, hell if it goes well enough you could probably start selling these
Those old 300's were so awesome. Run forever type engines. I think thats why they got away from them. My buddies 08 3 valve just imploded. No problem being too reliable here. Never missed a fluid change either.
I'd love to see this thing on a Dyno when you're done. It reminds me of the old 300 inline that was built with a Cleveland head modified for drag racing. I can't remember what racer did it but it was pretty impressive.
Power Nation has a series of vids where they did something like this in a few stages, plus a turbo. End result IIRC, was well over 500 horse on the Dyno.
@@artfranz2273 Not that I'm aware of...looked like a stock head. The selection of parts + turbo is what gave the figures...turbo is the great equalizer. 👍
Can’t wait to see this thing run!!!…..this thing is gonna be epic………do they make roller cams for these motors…..and a centrifugal supercharger or turbo would make this thing even more EPIC…….good luck my man
That's a real cool project. I always thought way didn't 1 of the big 3 didn't make a 350 ci. 4 valve straight 6 engine. 1 na .1 turbo with 4 bolt cross bolt block
I’ve heard of a couple of these but I’ve also heard that they usually have a big issue keeping the two parts of the head together and keeping all the water in the right places. This will be killer if this works.
Im interested on seeing how this goes… im gonna be building a 300 myself but i got the CNC promaxx head that was advertised on powernation… ill be ordering pistons here in a few weeks to bump up the compression ratio to right around 10:1 and will be getting better cam to go with it… im going to be shooting for 300-325 hp and hopefully 400 tq
if you get this to work there's no doubt it's going to make massive power we've all seen it done before with the Boss 302 heads but I think it's awesome that you're trying it with cathedral port LS heads I wouldn't be surprised if somebody starts making heads for the Ford 300 based off of this or the original design with the Boss 302 heads! if this was my project I would dykem the head and scribe out all the passages to match the head gasket or better yet get it o-ringed and use a copperhead gasket and do the same thing! this thing is going to be nuts if you can get it to work which it's definitely possible!
Piston ranch channel is doing the same thing except his is going to be fuel injection with turbo. Maybe y’all can get feedback from each other. I like this what you are doing.
I think I would put another set of coolant holes on the exhaust side. The ones on the intake side will flow coolant but were meant for steam to get out of the head. You may get a hot spot by cylinder 3 also because no coolant is flowing there like there normally would be.
here is to hoping that someone with a 5 axis will see this as a prototype and will start making heads from scratch. equipment is out there, smart people, too, just give them a reason
It appears that you've done your homework, thanks for sharing your idea. There's just something about an inline six for smoothness and balance; the Ford 300 (4.9 liter) is a great example of a stout piece; I hope that it produces up to your expectations. You made me subscriber so that I can keep up with your progress. Good luck.
You can get the bore spacing very close by offset boring but I decide to center cylinders number 2 and 5. So cylinders 1,3,4 and 6 are about .020 offset from the head. I dont believe it will be noticable.
Every once in a while we get to see something amazing on UA-cam. Keep us updated. I’m definitely interested. Love the big six Fords.

Laying the stock head gasket on the head and having it line up so close made me smile. Good luck with frankenstien!
Would like to see where this all ends up in torque, fuel economy, and driveability. Can't wait to see it all come together

Can’t wait to see this run would love to copy it for my personal truck if works. Hopefully the it’s stays cool enough for a daily driver.
I'm glad i fast forwarded to the end to find out that this guy was still talking with the camera still aimed at the same stuff as in the beginning of the video. It'll probably take him another 10 videos before we get to see this thing running.
This is absolutely nuts. Bravo.
Finally a unique LS
Very interesting build... I looking forward to what this head will do...🤩👍
6 in a row. Love the 300 6. I was sure this was all bull. Till I listened to you till the end. I can not wait to see what you do with it. How it acts. The surprises the short comings. Dam I wish I knew you bro.
It’s a monster!
Due to the lack of after market parts for these truck in their prime I can’t wait to see where this goes, hell if it goes well enough you could probably start selling these
Lmao please lol I'd give my uncle one as a gift he loves his 300 just put a head gasket in it though lol
This thing will be a TQ monster.. sub'd and looking forward to seeing it run.
Awesome work sir love to see more of your work on this
This is awesome can't wait to hear it run!
Those combustion chambers look eerily similar to the chambers in a Dodge/DeSoto/Chrysler polysphere 318/313 smallblock....
This is just too cool. Cannot wait to see it in action.
Those old 300's were so awesome. Run forever type engines. I think thats why they got away from them. My buddies 08 3 valve just imploded. No problem being too reliable here. Never missed a fluid change either.
I'd love to see the finished product and possibly some number
I'd love to see this thing on a Dyno when you're done. It reminds me of the old 300 inline that was built with a Cleveland head modified for drag racing. I can't remember what racer did it but it was pretty impressive.

I was thinking Bob Glidden made one thank you for the info. I clearly wasn't remembering correctly which is why I said I couldn't remember who did it.
Sherman Sligh built the first one, several followed after that.
Power Nation has a series of vids where they did something like this in a few stages, plus a turbo. End result IIRC, was well over 500 horse on the Dyno.
@@artfranz2273 Not that I'm aware of...looked like a stock head. The selection of parts + turbo is what gave the figures...turbo is the great equalizer. 👍
Love new ideas!! Can't wait to see it run!
It would be really interesting to see a stockish rebuilt 300 with this head package. I wonder what the before and after dyno results would be.
That is awesome! Subscribed. Can't wait to see the Dino run.
Sweet the 300 big six is one of my favorite engines ( 300 is very Chuck resistant)…..
Love this
Can’t wait for the results
Damn man. I love it. You should get an engineering award.
Can’t wait to see this thing run!!!…..this thing is gonna be epic………do they make roller cams for these motors…..and a centrifugal supercharger or turbo would make this thing even more EPIC…….good luck my man
This is AWESOME, nice job!!!
Wow. Excited to see this progress.
Very cool , can't wait for the results
That's so awesome. I need to try this for my 4.0 jeep
Love it! Keep it up brotha 👍
That's a real cool project. I always thought way didn't 1 of the big 3 didn't make a 350 ci. 4 valve straight 6 engine. 1 na .1 turbo with 4 bolt cross bolt block
Bruce Sizemore would be proud.
I'm excited to see the rest of the built!!!!!!!!
great job , i hope this motor pumps . i can't wait to see it done. i think i have seen this with a cleavland head .
Congratulations on making the 300 breathe!
I’ve heard of a couple of these but I’ve also heard that they usually have a big issue keeping the two parts of the head together and keeping all the water in the right places. This will be killer if this works.
Sounds like shoddy workmanship...
Super cool.. Subscribed! Need to see this work
great video dude, ive been meaning to make one of these for a awhile
Im interested on seeing how this goes… im gonna be building a 300 myself but i got the CNC promaxx head that was advertised on powernation… ill be ordering pistons here in a few weeks to bump up the compression ratio to right around 10:1 and will be getting better cam to go with it… im going to be shooting for 300-325 hp and hopefully 400 tq
Sin miedo al éxito papá!
Very cool! Subscribed and waiting for updates.
Cool project I would definitely reeled aluminum is tricky you could have tiny pin holes you can’t see
if you get this to work there's no doubt it's going to make massive power we've all seen it done before with the Boss 302 heads but I think it's awesome that you're trying it with cathedral port LS heads I wouldn't be surprised if somebody starts making heads for the Ford 300 based off of this or the original design with the Boss 302 heads! if this was my project I would dykem the head and scribe out all the passages to match the head gasket or better yet get it o-ringed and use a copperhead gasket and do the same thing! this thing is going to be nuts if you can get it to work which it's definitely possible!
This is awesome just imagine if it had 42lb injectors in each port!!!!
Badass work brethren
I'll be your 13th subscriber. Love the product. Looking to do this with a spare 300.
Really cool project , that’s real hotroding
subbed for this, wanna see more
Love where this is going! Maybe call it the Double Double, use in n out font.
Years ago, the hot setup on a Ford 300 was a head made from 351C 4V heads. And those were cast iron!
Piston ranch channel is doing the same thing except his is going to be fuel injection with turbo. Maybe y’all can get feedback from each other.
I like this what you are doing.
Awesome work.
Not sure if any boost would be wise. But love the thinking.
I think I would put another set of coolant holes on the exhaust side. The ones on the intake side will flow coolant but were meant for steam to get out of the head. You may get a hot spot by cylinder 3 also because no coolant is flowing there like there normally would be.
Nice project, 300 will take insane abuse with good rods.
here is to hoping that someone with a 5 axis will see this as a prototype and will start making heads from scratch. equipment is out there, smart people, too, just give them a reason
It appears that you've done your homework, thanks for sharing your idea. There's just something about an inline six for smoothness and balance; the Ford 300 (4.9 liter) is a great example of a stout piece; I hope that it produces up to your expectations. You made me subscriber so that I can keep up with your progress. Good luck.
Thats got some cool factor!!
4:48 I was wondering about the bore centers. That's an interesting solution.
You can get the bore spacing very close by offset boring but I decide to center cylinders number 2 and 5. So cylinders 1,3,4 and 6 are about .020 offset from the head. I dont believe it will be noticable.
Thats cool as heck!
Good going getting on Motor trend
The ultimate sacrilege. I love it!
