Id be crazy imagine fitting a 7.3 godzilla head on a 300 ford

This is hot rodding at its purest. Incredible work! Thank you for uploading this!

Reminds me of seeing when they did the Cleveland head on the 300-6 This is going to be a neat project. These heads have some advantages over the older style head, especially with the amount of compression you can run or boost very efficient. Can’t wait to see how it turns out.

Calvin (NIVLAC 57) pointed me in this direction. Lemme start by saying I have ZERO interest in building straight sixes, Ford or otherwise.. That said, I'm hooked.. The sheer BALLS on you guys...no million dollar CNC machines, just a buncha hand held tools and the sketchiest looking saw on yootoob..and I have no doubt you will be successful. Keep it up, very cool work!

I've done this a few times. What you have will work...sometimes. The end cylinders will have issues with the valves tagging the bores unless you cut the bores oversize, if you only make one cut-and join in the middle. To get the bores centered up on the valves, you need to make a cut between each set of head bolts, and weld it up. It isn't that much more work and allows proper porting to make BIG power. Also the stock 300-6 cam will put valve lift WAY up, as it had a pathetic rocker ratio with the stock head. You will need good quality aftermarket springs, as the 300 will rev HARD with 862 heads and the stock cam, and if you get a good balance job done the only limiter is the pistons holding up. With forgings, it is trivial to hit 7500RPM, and with a good quality damper and as light a flywheel and smallest diameter clutch you can live with, 8300RPM was as high as I had the testicular fortitude to go with mine. Mine has the forged HD crankshaft, there are a few left out there if you call the rebuilders and ask for one specifically. Stock rods are good to about 600ft-lbs of output at the crankshaft, then they start to bend. DO NOT trust the stock rod bolts.

That's pretty cool, I am working on a 351 Cleveland head on top of a 2.5 Jeep engine. The ultimate goal is cut a pair of Cleveland heads, weld them together and put it on a stroker 4.0 Jeep 6 cylinder.

I absolutely love Frankenstein stuff like this! Looks like you’re doing good work. Can’t wait to see the final product

And I'm over here still wishing they would make a modern Cleveland but now that everyone is jumping on the ev bandwagon and killing off the ice engine sadly it will never happen.Sorry,great idea and video.

Like I need yet another channel to peak my mechanical curiosity! I like this project! Would have loved to have been there for the question that started this project!

There’s a company in Australia that makes a v12 ls block, I bet you could buy a head from them that’s solid and ready to bolt on

Ford 7bearing bottom end and chevy top? Genius.

If it works RUN IT brother 👍

If I m not mistaken wood chippers, forklifts, etc all used the forged crank

I have seen it. Awesome technology at work here. Great content. Thanks EM.

In here from the Driveway Engineer group. Nice work! Looking forward to seeing how this works out. 👍

Love what your doing, just wish you had been able to use Yates heads for the purist in me but I get the value difference, I was amazed in the 70s when this was done with Cleveland heads and we had some ford trucks with these motors and we upped the compression when rebuilding them I tjink with Windsor pistons and they were rocket ships in comparison 😀

Ambitious - I love it and really looking forward to the next segment!

I noticed that scraper your were using, it reminds me of how I made my own scraper using a very heavy ga stainless steel Hyde scraper I squared up the edge to something like 87° not square but perfect for scraping aluminum heads and blocks.

Your so much more patient than I am cleaning that deck surface, I would have a disc or something cleaning it up in a few min

Try a few Australian sites… they’d had a guy build a DOHC for one, wish I could find it for you. Like you’re work 👍👍

I really hope for your sake that this works. Ls heads flow almost certainly better than anything else from that era.

Love stuff like this! Want one!

I want to put two volvo 4 banger 16 v heads on a LS. Funny I run into you here!

They USED to take 351 Cleveland 4V heads and cut one in the middle the middle and cut the ends off the other, then turn the middle section and weld it all up for a 351C 4 bbl headed 300L6, of course they used to bore and stroke the hell out of them as well.

I'd love to see this done! Cross flow 300-6. Should be a slick runner.

Love the carbon scrapers! Nice video

got me thinking of adapting 2.2 k car heads to a slant 6 overhead cams and all

I'm putting a Ryan Falconer V-12 (aircraft racing engine) head n my 6-71 blown Chevy I6 292.

That’s really cool.

Does this make the engine a Chord?

It's cool to watch creations like these come to life. Looking forward to the next videos. After this build what other builds you have in mind. Maybe a power adder to the "Franken 300"?

Make the head where I can just bolt it right on my Ford 300 engine. Make it gain at least 200 horsepower and I will pay pretty much what you ask.

This is what I like to see.

Pretty cool idea. Hope it works.

Hell yeah!

Ten speed is he GM/Ford combo would be perfect for this build

Dang man, that’s something I would never attempt!! Cudoes to you sir!!👍👊

damn, that is cool, now I really want to do a Slant 6 with a Hemi head!

Amazing!!! 😁

I'd assume the head halves will be bolted to the block and torqued to spec before welding to ensure they stay lined up... This is a really exciting idea and I'm looking forward to following.

Crazy but I like it!!😁

Hey after your all done you should 3d scan it and make it open for everyone to download we can revive forgotten straight 6s with 3d printed mockups then after you get it perfect you can send it off to a machine shop to be milled properly or you could try lost pla cast heads 😂

This is greaaat

have you considered leaving the head in 2 pieces and just welding shut the water jackets at the sawn ends? I am concerned about warpage and expansion is why I mention. Should be a way to tap in and connect to allow for coolant flow that can be easy to work with. I'm not familiar with the ford 300 head design, but it must be pretty bad for you to consider doing something like this.

Is that a Cologne block assembly over in the corner? What's that all about? . . . anyways, I'm putting together a plan to do a similar cross-flow Frankenhead on a Jeep 4.0L six. Just getting some ideas. It will be a while before I post any videos. Looks good, carry on. I love odd ball engines and engine mods. Greetings from Alaska.

Good job, you did it! What are you going to do with the coolant passages?

I know Cleveland heads have been adapted to the 300 six with amazing results. What kind of power are you aiming for? I would guess 350 to 400 hp is very possible.

Would love to see power figures for this project, and for someone to make ready heads available to purchase.

As an avid 300/6 lover (best Ford Motor ever), once you finish this and get everything completely together; have you or would you start building and selling kits for the 300?

LS swap Everything. In your case, each V8 has two heads, so only one LS had to be beheaded to make one Big Six 4.9 liter. Now, if three LS engines had to die to save one in line 300 six...that's would be Justice. what ya gotta doo Tall Man...

Will u try a toyota 20r/22r block next 🤔

Bore spacing different by 4.47 verses 4.40 inches for each cylinder.

What pistons are you planning to use? I heard that if you vote your block 390 feet pistons will work nicely.

I bet you can do this to any engine, even a 750 cc Reliant or Austin B-Series. What would it take to put LS head on the Austin B-Series?

almost looks professional.... you gonna have josh weld it? lol

Was this similarity stumbled on or what? Enquiring minds want to know.

What size carb you plan to run ?

What heads are you using? It seems like everyone doing this is using 706/862 heads from a 4.8 or 5.3 which yes it's cheapest and plentiful but wouldn't it be better to use 6liter heads so it's a matching 4" bore? I read the bore spacing on the 300 is 4.48 which is damn close to the ls 4.4 so I'd think that would work better but Id love to see it with both to know. I always wanted to do this since I read an article about a fellow who did it many moons ago but haven't had the time yet.

Didn't the aussies used to do this with Cleveland heads ? I think they would cut them up and leave them NOT joined so you ended up with 3 separate heads ? or maybe I was drinking that week ........

I seen a video of a guy who already done that

Can I buy a head thks

$100 says you don't make anything close to the HP I've seen other channels make from a real Ford 300, ;-)

But why??

Whut the hell

Great idea , terrible camera work, can’t see what you doing without repositioning view

I never understood why Ford didn't make a decent set of heads for this engine.

Foolish They made a Boss 300 with Cleveland heads in the 70's that made almost 700HP. That you will never come close to.

Wy Ls it over rated useFord Boss head

Your just making a ford gooder

If your going to do that much machine work why not go with a hemi head or a overhead camshaft arrangement? Chevy heads aren’t worth that much work/money.

dude....... you cut right thru the valve seat....... its never gonna be true again especially under heat and load......... HAVE FUUN!!
