Any plans for a heat shield under the intake?
Supercharged Ford 300 Engine Build

I remember reading in an Hot Rod magazine about a drag racer that used 302 heads cut and spliced together. Apparently the oil and water passages lined up. If I remember correctly it took three 302 heads to make a 300 head. Of course this was drag racing so durability may not have been an issue.

Yes this has been done for many years though Cleveland heads became the choice in Comp Eliminator.
There was enough of a demand that Allan Johnson (the top fuel crew cheif) who has a business whittling billet heads did a full billet head for the 300 6 cyl.
The straight 6's are till competitive in Comp, Steve Ambrose won a race in the last couple years with one and he regularly qualifies very well.

Thanks for the info Mario. I have always been a fan of Fords 300. I just kinda wondered if the 302 heads would make it easier or harder to supercharge.

I would think easier, many choices and lots of used ones out there. Plenty of aluminum one which would be much easier to cut and weld.
Also end up with a crossflow head, no intake exhaust interference.
Lot of machining and fitting to make it work

Would a 4.0 Aussie six crossflow head fit on a 300?

Honestly, I have no idea just went with it.
As far as heads go, I have had mine CNC ported and will flow right up there with the 302 heads. The only issue becomes everything on the same side of the engine. Even with that I have designed some new flanges that fit much better than anything stock and will work with the aftermarket intakes.

From what I've read and seen, the heads are the "choke point" on these engines. Other than that, they make a TON of torque. High torque engine + a Supercharger = Lots of fun.

Inspired by your efforts and having driven one in an F250 years ago, I've been reading about other Ford 300 six cylinder builds. Some pretty amazing work out there.

He used to work for Ford. I believe he said Ford had a pallet of them scheduled for destruction but one of them 'fit into his lunchbox'. He's a member over at fordsix.com.
I love your project, 1956f100!

Thats a pretty slick looking piece. This project is too cool.
Here is another Ford 300-6 that has some pretty interesting engineering.

Great job! Hope it runs as well as it looks after all these mods..The 300 is a great engine, no surprise it was used as industrial engine around the world.

Very cool project. What will the rest of the drivetrain be like? Standard or automatic? What is the intended use when finished?

Manual T5 for now, I have been debating rebuilding it with an Astro kit, or just selling it and buying a tko-500. You can pick up a tko for not much more than the cost of astro rebuild.
It is just a driver, 1956 F100.

Back in the 60's Ford had 2 inline 6 cylinders. The small block (144, 170, 200, 250) and the big block (240, 300). The Aussie 6 cylinder engines are a direct decendant od the small block.
Having said that, I don't know if any of the key dimensions (bore spacing, head bolt locations, etc) have been carried forward.

once ford oz developed the alloy heads and x-flow heads full compatability was lost - US I6 block interchangeability was lost after the Oz XC Falcon developments (circa 1976-77)
I know of a number of US friends who used to import the entire engines because it was the best way to go about it
I think US NDRA changed the rules for inline 6's at one stage as the Oz x-flows were seen as unfair competition.
The last classic Oz small block I6 with US heritage was in the Aust XC series falcon and TE series Cortinas.
The largest Oz classic 6 was the 250 CID. Australian 200 and 250 CID I6's also ran separate heads and inlet manifolds - whereas US legacy 170 - 221's ran a logged head (ie inlet man and head were single cast).
Delogged heads on Oz falcons started circa 1970. The blocks were similar, but the heads were completely different - although Oz 200 and 250 CID heads will fit on US 170 and 221's
I ran a few worked 221's with delogged 250 heads
BTW the wiki entry on Australian falcon 6 development is incorrect in a number of areas
these are far more accurate references

Oz 250 x-flow sixes were also interesting in the fact that they used some Cleveland V8 bits

Nothing as of now........
Between the little odds and ends projects that pop up in daily life, the shop build, and this truck things are slow moving.
I hope I can get the shop buttoned up this year and moved in. Then I can devote my attention to the truck!

I just found your thread and think it is very cool. I race these motors along with the 240 in vintage modifieds
