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.

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.

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!

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!

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

[stellingbanjodude]

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

[TurboWorld]

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

[erniemathews]

Ford 7bearing bottom end and chevy top? Genius.

[Hitman-dsei]

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 😀

[marlobreding]

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.

[jram]

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

[dustinandtarynwolfe]

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

[sabgab]

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.

[danmeehan]

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

[SPEEDFREAK]

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.

[edsmachine]

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

[BoringFisherman]

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