Did you ever pressure check your evaporator to make sure there are no leaks? I was thinking about pressurizing it and spraying soapy water on it to verify no leaks.

question...I almost have my heater box out but it seems to be hung up on something. Are there a few screws that you have to take out from the heater duct that is to the left of the glove box opening? I was able to remove the heater duct that supplies air to the far right air duct. My thinking is the box is still somehow connected to the air duct in the middle portion of the dash. Any help would be appreciated.

What is the piece called that the carb mounts on ? Not the intake but the thing that has the lines that run into the exhaust?

WTF is happening with your camera ?

Nice job, step by step; thank you for the video😊

I think that's pretty amazing. Don't get why nobody has aftermarket 300 head stuff.. you just go make it.. amazing really..

Very well done, any air purging?

I need you to come do mine 😂. Thank you for the video. About how long does this job take for someone that isnt a pro? Also a lady haha

Random, im working on one as well, figured id see whats online bored and cant sleep and fojnd this, awesome stuff man!

Got a question. That battery wire from the distributor, where did you end up hooking it to in the battery area? If that makes sense.

Nicely done!

Good Video , nice job , thanks for posting !👍

Can you send me a link for the 2 parts

I have a 1966 ford truck 6 cylinder want to change distributor but dont come out does it have a pin?

There were rumors going around in the mid 2000's of a crossflow head designed by ford. They were experimental and tried for ups so the story goes. One surfaced on the forums for sale. There were less than 6 made total.

One way I see this working, is to use over head cam.

I had the idea to graft one and a half 7.3 IDI or 7.3 Powerstroke heads onto a 300. I wanted to experiment with making a diesel 300, and I realized that the 7.3 and the 300 both have 4 inch bores. I haven't gone anywhere with the idea, but I want to try it eventually. The tough part would be the head bolts since a 300 is 4 bolt, a 7.3 IDI is 5 bolt, and a 7.3 Powerstroke is 6 bolt. Either way, crossflow 300 is big mint. I love the 300, but I hate reverse flow heads.

Ford 300cu bore spacing = 4.480 inches Aussie Ford 250/250 crossflow & later bore spacing = 4.08inches Perhaps try to find an Aussie '74 to '87 crossflow head to scan OR stike lucky & find one online somewhere & re-scale it in CAD & feed the details into a CNC mill? If nothing else, it should give you some ideas for solving some of the problems you are or will face... Looking forward to see how you go with project, best of luck & thanks for sharing! ;)

I know there are a few guys mentioning LS heads in the comments, but another option with even closer bore spacing is the modern Chrysler Hemi motor. The bore spacing is 4.46 compared to the Ford 300's 4.480. The 5.7 Chrysler has a little bit smaller bore diameter. Could be a lot easier option if the bolt pattern lines up or is close.

Excellent idea and video. A lot of great thought processing. I'll be looking forward to seeing how this works out.

Yeah as stated in this post ! Ford Australia took the 144 through 250 ci Falcon Six and gave it Cross Flow Cleveland style cantered valve heads in 1979 , same valve angles and infact valves as Cleveland V8 . Later cast in Alloy and multi port injection in 1983/4 . The 200 ci and 250 ci six got this head . Alloy ones cast by Honda in Japan . These heads are a direct bolt on for any US 144, 170, 188, 200 and 250 six .

My new distributor came without the shaft

Original style head gasket would be required and is a template, Australia had the falcon 4.1 litre 250 cube crossflow 6 from the 70's. Remember that a fail is learning which leads to experience 😊 good luck.

Why couldn't he buy a head gasket

Did almost the same thing on my old 86 after the wiring harness had a thermal event...... I just used mid 70s Ford distributor and module instead of a HEI

It's impossible! Hope this helps you keep it going! I've been thinking about the same project. I like the idea of the factory exhaust manifold, and relocating the spark plugs and intake ports. I was thinking about mimicking the LS intake ports (tall and skinny) this would require a custom intake though

What about the new ford Godzila engine? They say it is basicly the same as the LS?

At this point doesn’t make more sense build an over head cams head? U can make it belt driven and have 0 problems with push rods

So much work anyway, why not go OHC?

Did u check to see if the Aussie later xflow Ford head would fit ?

i wonder if you could just let the pushrod holes interfere with the intake, and then press in a tube?

As many others have said, go get an Aussie 250 crossflow head You won't be able to use it because the bore spacing is 4.08" compared to the 4.48" spacing of the 300, but at least it will give you some ideas about a decent design Better still just throw the 300 in the bin and stick a DOHC Barra in your car !

You are a real Hotroder ! Maybe a Winsor head like trick flow will be😊 easier to cobble up.

I remember years ago that Clifford had planned a crossflow head for the 300, and never did it. It's really the only thing I hate about the engine.

It’s impossible, now get it done so I can get one as well lol. Honestly , I think you should reference the Cummins head, since they are both OHV , 12v design , injectors go on the driver side of the head , Maybe adding a little meat on both sides of the head would help centering those pushrods a little so you can initially make the intake and exhaust ports maybe cone in ? Maybe just an opinion

Couldn't you use a head gasket for the dimensions?

I agree with using the stock manifold configurations if possible. Have you concidered the boss 302/351C head design instead of the LS? The canted valve arrangement might solve some of the issuses you are having wth the LS? Never know....

Isn't fords pinto 4 cylinder a cross flow just add 2?.

I had a '94 F150 4.9 w/ M5OD for a few years. Loved that truck. I don't know how to use CAD, but I have a DOHC idea I can share with you. Will draw them up. Just need to know how to email them to you.

Those 300 heads are not easy to find. I was running a 300 about 20 years ago and cracked a head, nobody had one, one local shop even told me if I should find any to please tell them. They did service for UPS and thats what they ran in their trucks so they ran through alot of them. I got lucky and found one at an old closed down junkyard, they only had one.

Look at the FE Ford head cyl spacing is very close to the 300 cyl spacing go the the salvage yard and get 4 of them cut them up and weld back together with the correct cyl spacing then cut the assembly in half and get your water passage mold. Then find someone (like Edelbrock) to cast it in Aluminum

also look into the doge gen3 hemi head very close to bore spacing for a hybrid system

Don't wanna be a stick in the mud but, couldn't you use a head gasket for a templet a little sturdier than paper.

Waving your hand during the video is distracting, annoying, and adds no quality at all.

The rocker studs valve stems and push rods need to be in line. Off vertical push rods will probably bend

australia had a crossflow head on the ford 250cui six that preeceded the awsome barra,,,

Maybe a hemi head would work

There is a UA-cam video of a Cleveland head on a 300

WHAT is the attraction about hotrodding 300 Fords.Hardly ideal as a performance engine with a heavy crank and 4" stroke. Excellent torquey truck engine however. As it was designed to be. I have seen them used in 70s speedway Supermodifieds where they rasped around at moderate speed. The best had a one of constant flow injection. That car is still around though inactive. A few tried the 292 Chev 6 as well. To my mind a better engine BUT also obsolete. IF you want a good more modern straight 6 used a crossflow 250ci Falcon engine pushrod engine. Or better the same base engine with the twincam head, The Barra. Or modern Chevy 6 engines
