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.

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'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.
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
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.
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.
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. 👍
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.
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.
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.
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
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.
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
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
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!
Very cool! One thing I think you were mistaking is it would be .040" off on the 2 center bores and the same amount on the 2 outer bores, not .020", but still very doable that way. Here's why, the F300 has a bore center of 4.480" and the LS has the same bore spacing as the sbc platform they replaced of 4.400". .080"/2 = .040". So you had to add an extra .160" in the center to make this work, good thinking to make it happen. I'm subscribed, can't wait to see this fire up! Are you on Inline 6 I think it's called IIRC? Cool stuff.
Yes you are right, I wasn't thinking the chevys were 4.440" for some reason. That is the reason the smaller bore 5.3 heads are better fit the the 6.0 4 inch bore heads. But they still might work. I would like to use the 823 ls3 heads if they will fit.
@@fiskshopworx1541 So are the outer bores more misaligned than you thought they were? If you only added .080" in the center instead of .160", the 2 center bores would be the ones that are centered. And by the time you got to the outer bores they would be .120" off. In the video it doesn't look that far off, so maybe you lucked out and added more than .080" in the center? Did you know the Chrysler small blocks and the newer Hemis have a 4.460" bore spacing? If you're thinking about doing another one, a set of Hemi heads on one would be REALLY cool. I'm not sure what the valve orientation is so it may need a custom cam?(probably)
@@itseithergonnaworkoritaint7852 the jig build to weld the heads together centered the number 2 and number 5 cylinders. Yes ihave looked into a newer hemi heads, the valve sequence is backward and the pushrod spacing is wide I believe, IL like to get a junk head and line it up with gasket to see if it possible. Hemi heads flow very well with bigger displacement cylinder.
@@fiskshopworx1541 Sweet! so you accidently did add .160" to the center then, you can't ask for a better accident than that! Here's what I looked into for the F300, using the NASCAR R5/P7 Chrysler heads. 410 in. cfm with the very same bore spacing as the F300. The bad part is it would absolutely require a custom cam or to weld sections from 3 heads together. Instead I will use the 2 sets I have of those on a couple different big blocks I have. I have a MOPAR 383 that I can get over 500 cid with that those heads would do a good job feeding it air/fuel. The other one will be a BBB or a Buick Nailhead, probably the Nailhead because it's a stronger block but not sure yet?
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.
The 3/8ths pushrods will work fine if you order them with a thick wall. Schnieder racing cams have some wicked 300 Ford cams but I like your selection since I'm a fan of narrow lobe centers. Can you discuss your welding??? Machine used, gas mix, settings........???
My brother did the welding, I built a jig from 3/4 steel plate to bolt the head to when he welded it. He also heated the head up before and while he was welding using a l.p. fish fryer. It still warped about .015 but I hadn't resurface afterwards.
@@fiskshopworx1541 .015 warpage in a head that long is outstanding, just ask Brodix. They commonly have warpage in damaged customer heads that they have to weld and those heads only 4 cylinders long.
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.
That's pretty cool.Nice job. I have a '53 F100 body mounted on a '79 F250 4x4 frame with a 5 speed tranny and a 300-6.I have thought about doing this also. You have inspired me.Nice to see you are thinking outside the box.I'm looking forward to updates. I have several heads and blocks and wonder if a head or block could be used as a jig for welding?I weld aluminum and really like this kind of stuff.This could be pre and post heated with a tiger torch.
Do it to it! '53-54 are my favorite trucks. That would definitely be something to see at a show. Only so many LS and SBC swaps I can stomach anymore. If we're gonna have them, why not do something different with them?
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’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.
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.
I think I would use aluminum heads just for a better weld and eas of milling. But I really wonder why , down draft carbs ? I've wanted to do it for a long time. Maybe I'll get to it when I retire.
I think it's a catch 22 unfortunately. Not too many companies make performance parts for the 300 because it's not seen as a performance engine But the reason it's not seen as a performance engine is because not enough companies make performance parts for it.
Im doing something similar for a Ford 200 using individually cut Chrysler pushrod v6 combustion chamber head sections all welded together... To make a cross flow head... I have a question regarding your welding procedure... Did you have to re-heat treat your aluminum head to a T6 grade after joining the heads with welding? I definitely think I will since it's definitely gonna soak up heat when I either braze or tig weld them together... But perhaps I'm over thinking it ... Love to hear your wisdom on the matter... -Evan
Would 317 heads work well being a 4" bore, the larger chambers would be milled down some to true up after the welding and why not cut holes in the plate for coolant Flow
One cool idea...I wonder if a tri-Y header would work well on that set up? Basically have 3 pairs of corresponding cylinders Y together to aid scavenging then merge into a 3 into 1 cone collector, I would guess a single 3" collector would be plenty. I have seen tests where a mild LS engine with a single 3" collector performed better than 2.5" duals, that was on Engine Masters or Richard Holdner I believe, maybe a 2.5" or 2.75" would be better with lower displacement? It would be cool to see it with port injection, LS coils and a single 92mm TB. I would guess a longer runner length would produce the the most TQ and mid range without effecting peak HP since a long runner TBSS intake on a cathedral port LS is the best performing factory intake.
Your header idea might work, I kinda just used what I had and the 2 collectors will be merging into a 3.5 inch and one single side pipeon the car. A crank sensor and ls coils would be a nice setup also.
That is way to cool and u are probably the first one to ever make a LS 4.9 ford head . I can't wait to see this thing run .did u have to get a custom cam :made?
@@fiskshopworx1541 oh ok that worked out perfectly then, i know that they have put them on some v8s and had to get a custom cam ground for it so i was thinking that would be the same. Have you got it running yet?
Awesome job! Can hardly wait to hear it run! Any templates available fir cutting the heads? What kind of aluminum rod was used for welding the heads up? Any other details, templates etc you could share?
4043 1/8 rod, I built a plate to bolt the heads to for the heating and welding process. I just used a big band saw for cutting. Cut a little big and can mil off to get were need to be for length.
I would love to talk with you sometime about this, I have a very similar build going on right now with the exception of doing efi. Your doing a great job!

@@trillrifaxegrindor4411 Bruce Sizemore was only guy i ever heard doing this.
@@trillrifaxegrindor4411 so ur letting it be known that ur policing up the randoms because you know how many there is & where they are & ur telling random ppl this to get the word out ur the law on these so called randoms & they are not gonna be allowed to steal another person’s glory because they made there story up or are ridding on another man’s shirt tail claiming they invented this amazing drag engine that no other person could ever fathom putting it together & making it work & that this engine was his only precious & him & the engine was one together as you showed him how fast you could throw large random objects up ur a**
@@chadsmith8418 🤣🤣 I am nearly crying damn that was funny
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.
Those heads cost a LOT more than 706/862.
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.
I feel that's pretty amazing that most of the machining was spot that on I wish you luck I'm looking forward to seeing the next video
Wow. I can't believe you actually did this! This is crazy! looking forward to a finished product!
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
Seen this done with boss 302 heads and it worked fantastic. Good luck dude. Can't wait to see more of the build.
Congratulations on making the 300 breathe!
OK, this is some heavy dedication to an engine-series. I assume you got tired of everyone saying "just stick a 351 in it" :)
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.
If you do it film the fitting and welding please.
Sweet the 300 big six is one of my favorite engines ( 300 is very Chuck resistant)…..
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.
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.
Bruce Sizemore
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. 👍
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.
I did the same but did it in three pieces for better bore spacing, haven't tried it yet
This is SUCH a great idea. All of the big sixes need a crossflow head SO badly. I hope this runs like a scalded dog....
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.
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 is awesome to finally see one off the block. Curious to see how it runs.
Now this is something different! A cathedral headed Ford 300, inline 6……. Don’t see that every day
Excellent. I've talked about a similar setup before but haven't had the opportunity. Great job.
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.
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.
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
This is fantastic, cant wait to see a video of the engine assembly and running
I'd love to see the finished product and possibly some number
Love where this is going! Maybe call it the Double Double, use in n out font.
Damn man. I love it. You should get an engineering award.
you REALLY need to get this stuff to Richard Holdner!!!!
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.
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 .
Awesome work by the way. I'll be waiting for an update on this project for sure.
Really cool project , that’s real hotroding
This thing will be a TQ monster.. sub'd and looking forward to seeing it run.
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.
For sure gonna be interesting to see the finish product.
A machine is a machine.
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.
Fascinating.
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.
This is wild! Can't wait to see how it turns out! Props for doing something different!
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
That is a work of art..quite special for sure,thanks for sharing
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
Cool project I would definitely reeled aluminum is tricky you could have tiny pin holes you can’t see
This is awesome just imagine if it had 42lb injectors in each port!!!!
That is amazing. I can’t wait to see the finished product
I subscribed and can't wait to see this in the future. I love this kind of stuff.
Nicely done sir. I look forward to seeing it running
This is an awesome idea. Looking forward to seeing the final product
Finally a unique LS
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...
Look up "Boss 300“
Look up Clifford Performance. They make performance parts for old inline sixes, and the lima 2.3
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!
It would interesting to see the performance and cost comparison between this and a Ford Barra I6.
I'm working on a couple of Cleveland headed projects. One is a Jeep 2.5 4 cylinder and the other is a welded together set on a Jeep.4.0.
That's cool project.
This is absolutely nuts. Bravo.
This reminds me of when someone on TH-cam put a set of LS heads on a 351W search 351LS if anyone is interested
Very cool! One thing I think you were mistaking is it would be .040" off on the 2 center bores and the same amount on the 2 outer bores, not .020", but still very doable that way.
Here's why, the F300 has a bore center of 4.480" and the LS has the same bore spacing as the sbc platform they replaced of 4.400". .080"/2 = .040". So you had to add an extra .160" in the center to make this work, good thinking to make it happen.
I'm subscribed, can't wait to see this fire up! Are you on Inline 6 I think it's called IIRC? Cool stuff.
Yes you are right, I wasn't thinking the chevys were 4.440" for some reason. That is the reason the smaller bore 5.3 heads are better fit the the 6.0 4 inch bore heads. But they still might work. I would like to use the 823 ls3 heads if they will fit.
@@fiskshopworx1541
So are the outer bores more misaligned than you thought they were? If you only added .080" in the center instead of .160", the 2 center bores would be the ones that are centered. And by the time you got to the outer bores they would be .120" off.
In the video it doesn't look that far off, so maybe you lucked out and added more than .080" in the center?
Did you know the Chrysler small blocks and the newer Hemis have a 4.460" bore spacing? If you're thinking about doing another one, a set of Hemi heads on one would be REALLY cool. I'm not sure what the valve orientation is so it may need a custom cam?(probably)
@@itseithergonnaworkoritaint7852 the jig build to weld the heads together centered the number 2 and number 5 cylinders. Yes ihave looked into a newer hemi heads, the valve sequence is backward and the pushrod spacing is wide I believe, IL like to get a junk head and line it up with gasket to see if it possible. Hemi heads flow very well with bigger displacement cylinder.
@@fiskshopworx1541
Sweet! so you accidently did add .160" to the center then, you can't ask for a better accident than that!
Here's what I looked into for the F300, using the NASCAR R5/P7 Chrysler heads. 410 in. cfm with the very same bore spacing as the F300. The bad part is it would absolutely require a custom cam or to weld sections from 3 heads together.
Instead I will use the 2 sets I have of those on a couple different big blocks I have. I have a MOPAR 383 that I can get over 500 cid with that those heads would do a good job feeding it air/fuel. The other one will be a BBB or a Buick Nailhead, probably the Nailhead because it's a stronger block but not sure yet?
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.
The 3/8ths pushrods will work fine if you order them with a thick wall.
Schnieder racing cams have some wicked 300 Ford cams but I like your selection since I'm a fan of narrow lobe centers.
Can you discuss your welding??? Machine used, gas mix, settings........???
My brother did the welding, I built a jig from 3/4 steel plate to bolt the head to when he welded it. He also heated the head up before and while he was welding using a l.p. fish fryer. It still warped about .015 but I hadn't resurface afterwards.
@@fiskshopworx1541 .015 warpage in a head that long is outstanding, just ask Brodix. They commonly have warpage in damaged customer heads that they have to weld and those heads only 4 cylinders long.
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.
That's pretty cool.Nice job.
I have a '53 F100 body mounted on a '79 F250 4x4 frame with a 5 speed tranny and a 300-6.I have thought about doing this also.
You have inspired me.Nice to see you are thinking outside the box.I'm looking forward to updates.
I have several heads and blocks and wonder if a head or block could be used as a jig for welding?I weld aluminum and really like this kind of stuff.This could be pre and post heated with a tiger torch.
Look up "300 boss"
Do it to it! '53-54 are my favorite trucks. That would definitely be something to see at a show. Only so many LS and SBC swaps I can stomach anymore. If we're gonna have them, why not do something different with them?
Just put a Chevy ls in it🤣
I think a properly executed turbo setup would be much easier ...
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 project, definitely following!
I hope it turns out great.
I would seriously drive this to an LS Fest event and dare them to throw me out !!!!!
Got a LS½ in here, what you mean I can't come in? Do I look like Rob Dahm to you?!
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...
That is awesome! Subscribed. Can't wait to see the Dino run.
That's so awesome. I need to try this for my 4.0 jeep
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.
I'm excited to see the rest of the built!!!!!!!!
Years ago, the hot setup on a Ford 300 was a head made from 351C 4V heads. And those were cast iron!
I think I would use aluminum heads just for a better weld and eas of milling.
But I really wonder why , down draft carbs ?
I've wanted to do it for a long time.
Maybe I'll get to it when I retire.
Looks sick man, nice work
This is hot rodding @ it's best. I still wonder why eldebrock or someone has not made a head like this , there are tons of these engines around
Seriously, they make one for the jeeps. Just as many 300's and 240's
I think it's a catch 22 unfortunately.
Not too many companies make performance parts for the 300 because it's not seen as a performance engine
But the reason it's not seen as a performance engine is because not enough companies make performance parts for it.
@@prtyof4156 A crossflow head?
Please give us an update! This is such a cool project!
Im doing something similar for a Ford 200 using individually cut Chrysler pushrod v6 combustion chamber head sections all welded together... To make a cross flow head... I have a question regarding your welding procedure...
Did you have to re-heat treat your aluminum head to a T6 grade after joining the heads with welding?
I definitely think I will since it's definitely gonna soak up heat when I either braze or tig weld them together...
But perhaps I'm over thinking it ...
Love to hear your wisdom on the matter...
-Evan
Excellent idea but it might be worth looking at getting a second hand one shipped from Australia (with intake manifold).
But what's the fun in that?
Would 317 heads work well being a 4" bore, the larger chambers would be milled down some to true up after the welding and why not cut holes in the plate for coolant Flow
Going to run electronic ignition? LS coils and whatnot?
Might look kinda funny with the plug wires running up and over the valve cover 😁
One cool idea...I wonder if a tri-Y header would work well on that set up? Basically have 3 pairs of corresponding cylinders Y together to aid scavenging then merge into a 3 into 1 cone collector, I would guess a single 3" collector would be plenty. I have seen tests where a mild LS engine with a single 3" collector performed better than 2.5" duals, that was on Engine Masters or Richard Holdner I believe, maybe a 2.5" or 2.75" would be better with lower displacement? It would be cool to see it with port injection, LS coils and a single 92mm TB. I would guess a longer runner length would produce the the most TQ and mid range without effecting peak HP since a long runner TBSS intake on a cathedral port LS is the best performing factory intake.
Your header idea might work, I kinda just used what I had and the 2 collectors will be merging into a 3.5 inch and one single side pipeon the car. A crank sensor and ls coils would be a nice setup also.
@@fiskshopworx1541 coil on plug is nice
Very interesting build... I looking forward to what this head will do...🤩👍
That is way to cool and u are probably the first one to ever make a LS 4.9 ford head . I can't wait to see this thing run .did u have to get a custom cam :made?
No the valve sequence is the same on an LS and the ford 300. So an off the shelf camshaft works.
@@fiskshopworx1541 oh ok that worked out perfectly then, i know that they have put them on some v8s and had to get a custom cam ground for it so i was thinking that would be the same. Have you got it running yet?
@@79beans347 no,I am waiting to get the bottom end back from the machine shop.
I like it !! I have a 292 with Cleveland heads injection
Exactly the combination I was thinking about in my head but I was to de stroke it to 3.85
Cool. Wonder id the 2014 and up LS based 4.3 heads would be easier to fit? Not many in the junkyard yet though.
One of the reasons it's better to use the V8 heads is because you want to lop one end off each head to attach 6 together.
Thats got some cool factor!!
Awesome job! Can hardly wait to hear it run!
Any templates available fir cutting the heads? What kind of aluminum rod was used for welding the heads up? Any other details, templates etc you could share?
4043 1/8 rod, I built a plate to bolt the heads to for the heating and welding process. I just used a big band saw for cutting. Cut a little big and can mil off to get were need to be for length.
@@fiskshopworx1541 thanks for the information.
The ultimate sacrilege. I love it!
That is some old school hot ridding right there.
This is awesome can't wait to hear it run!
Was looking at an LV3 GM V6 with the intake off thinking those heads would only need about an inch shaved off each one to fit on a 300....
Awesome work.
Not sure if any boost would be wise. But love the thinking.
Sin miedo al éxito papá!
I would love to talk with you sometime about this, I have a very similar build going on right now with the exception of doing efi. Your doing a great job!
This is just too cool. Cannot wait to see it in action.
