225 Hemi head

-
No what I sent you was Chrysler stuff. The Dodge stuff is a good bit smaller.
 
I think it would be interesting for someone with the backing like wild or Rumble to look one over and see what they think the biggest issue is, valve size or runners. I say that because a lot more valve could be stuffed in there than people want to work for.
 
more fake stuff

What about Mitsubishi 2.6L / G54B / 4G54 Heads grafted together to get 6 cylinders? (Don't mind the Pulley on the back of the head, it came from a Caravan and the pulley was for the Power Steering Pump in FWD applications)





They're a Crossflow Overhead Cam Aluminum Hemi Head, Pushrod location no longer means diddly crap :D Someone would just have to figure out how to drive the Overhead Cam, and obviously it'd require a custom cam and longer Rocker Shafts (but you're gonna need just as much going to pushrod route)

4.02" Bore Spacing

1.81 / 1.55" Intake & Exhaust Valves (stock).

Oh and they're still available in Aftermarket castings, factory heads are a dime a dozen too (I had probably 10 of em here, couldn't even give em away, started hauling em in for scrap weight). And did I mention there's also 16V DOHC versions out there too?


I don't have any /6's here any more to compare a 2.6L head to, the biggest Issue I can imagine would probably be Bolt Holes & Coolant Passages not lining up. Can something like that be relocated on an Aluminum Head??? I imagine it'd be possible, if people are going as far as welding heads together.

The other issue. (LOL) The spark plugs don't come up through the middle of the valve cover like our beloved Hemi's :D but it's still a Hemi Head.


EDIT : My bad, the DOHC version is a 12 Valve, not a 16. Sorry.
 
seems to me there was a chrysler engineer who got his hands on a mould of some sort that Chrysler was experimenting with

thats what the story is anyway

if its the story im thinkin about the eng. developed a single OHC head in which the cam was driven from the crank flange (gear driven)

Was on craigslist (Detroit?) a few months ago. Chryco engineer fabrication.

I don't think its photoshopped. I think its a real hemi head with the outboard cylinders added to keep script intact. That intake looks a little shaky but bolting it up...bigger challenge is: where are the pushrods coming from?

From someone who has done the research (or, read about it,) what is the short answer to the question of, why can't a Toyota 24-valve head from a Supra Turbo be adapted to a slant six block?

Looks like the bore-center spacing might be close... Is it?

If they can put a 351 Cleveland Ford head on a 300cid Ford-six, This MIGHT be possible with a lot of work...

Is it not????

Thanks for any information...
 
He had all that on Ebay a while back. Cool stuff.....but I gotta say it. The slant six is a marvel in and of itself because of what it is. Putting a hemi head, OHC head or other exotic things take it away from what it is, IMO. It's not a slant six anymore. Stuff like porting the head, bigger valves, better induction and exhaust and even EFI don't really change the root of the engine. That's my opinion, whether you agree with it or not.

Yah, some people get bored easily and have to fiddle.....I agree the slant 6:prayer: is a marvel just as Ma Mopar intended.
 
I say if ya got the $$$$ find ya a damn good machinist and a block of Aluminum, and get a /6 225 block and for Christ sakes have at it......... a GOOD machinist CAN make that happen with the right $$$$ to grease his palms a bit.

I've seen stuff done that we all would NEVER even imagine, some of which I do myself.... but this? I'm NOT that good!
 
wanna see another wild hemi project,, on ly 3 exsist if i remember correctly and only 1 runs,, i seen it at chrysler at carlisle in the old tom hooovers mover notch cuda at that time currrently owned by dick landy 2008 its called the ball stud hemi,,, chrysler ran out of money to do further testing,,, but i like the slant 6 hemi fake or not,,

not sure I completely understand this version of the Hemi. I know it was done or well was going to be, for cost of manufacture, BUT wasn't, not sure why, BUT the real deal is just that. A legend these days and will continue to be, BUT why? I really mean WHY? you know? It was pretty much untouchable for its time, why make a "different" version of the V-8 when the original was so great to start with? All due to money?

SO being said that, WHY did Aussie (no offense guys) get Hemi-6's and not us in the USA? IF the design for its time was so good, WHY didn't they mass produce them everywhere? Some law restrict it? Can't say I understand that due to the much larger beast we all love and would cherish if we had one.....

THEN, if you had a 225 and a 245 block what was the difference between the heads in so as much to have a 225 head, "Hemi" milled? They were doing it by the head "placement" in the shops at Mopar anyway, so. mill out a 225 head to be Hemispherical.... BUT this also says something, I to date have never seen the underside or piston side of a normal /6 head, OR the Hemi version to see if that machine work is even possible!

BUT, with the bore, stroke, and the distance from one cylinder to the next, I'm not sure if I'm looking at this correctly. I know the whole rod connection from the cam, or through-ways might be an issue due to the angle they are in the Hemi head.. BUT the OHC would cure that issue, wouldn't it?

Bears the question, what (if this would work) what sort of Horsepower and torque might something like that, have? I mean the |6's are known for their torque ratings, what might a Hemi version be like?

Then you got those that are purists......The Hemi |6 is a "U" head flow......The Hemi purists would have it be a cross flow, how would that fit in a car from a \6? And even if either was good....... what sort of difference would the "U" flow to the cross flow have on any one single engine CID?

Even say it was possible. BUT, limited space for a \6 Hemi 225 or so....Whats to say you reverse the flow? Mostly, you have the head, flowing on a in-line 6 cylinder from the left side.....(that's is, setting in the drivers seat) WHY, suppose to have this cross flow. OK? You got the manifold/header on the left side, and the intake from the right side, reverse this, put the exhaust on the right, (you can ALWAYS make pipes fit a bit better even if factory Mopar manifolds were used....SO, this would open up the point of intake, to get a "Ram Induction" set up, if more power was seeked out, and would allow a bit more room for aftermarket parts for even higher HP ratings, and torque as well......

The engine would still fire the same, just being fed from a different side, to exhaust from a different side... I'm not sure a space issue was the issue along with the cam issue as that can be remedied by an OHC system. be a good power point as this motor type I bet would produce V-8 HP on In-Line 6 gas mileage.....

Down Under we had our Hemi six. We raced this engine. It did very in New Zealand.

Great motors but they are not a hemi, i dont think they are even a canted valve.
 
Here are pics of engine blocks.....Slant 225, Hemi 245, and a Holden 202.
The 245 and the 202 have 7 main bearings.
