Part 1 Australian Chrysler Valiant Hemi 6 Pull Down. Response to UTG Chrysler 6 video. - Top end

Click here for the re-edited version, where I tried to remove some of the shakiness.
• Re-edit - Part 1 Austr...
Please go easy on your criticism, this is my first attempt, using a head mounted camera for most of it, so I couldn't really see exactly where it was pointed. As for the shocking editing, just a 60yo trying to learn new tech. I will try to improve the quality as I go. Hopefully plenty more videos to come, as I work out what I'm doing, so if you feel so inclined, please leave a like and subscribe.
Thanks for watching.

At 2:50 yeah I goofed, and added an extra intake port to the slant description 😆

[@eugenepolan1750]

...for better breathing!

[@sandgroperlivinginadelaide6998]

Well done. Great video

[@billjamison2877]

Interesting video! A HEMI Six! I remember quite well rebuilding my Leaning Tower of Power 225 Slant Six in my '64 Dodge 330 back in 1970. Had over 200,000 miles on it when I rebuilt it and got another 60,000 out of it and traded it in on my 1969 Roadrunner . Take me back to those days! Always loved tearing down and rebuilding engines of all kinds.

[@stevebooher7419]

Thanks for the video! Somebody needs to ship one of these to Uncle Tony and send him off on a whole new tangent regarding Mopar engines.

[@TAVOAu]

Yes, I did manage to extract the remains of that broken head bolt, without too much pain, and no damage to the block.

[@waiting4aliens]

Thank you for educating us.

[@lautburns4829]

Thanks from many UTG followers. Your effort will definitely go unrewarded .😂😂😂👍

[@johnmollet2637]

Thanks foe posting this, I've always heard of those engines, but never laid eyes on one. Did not expect to see that it was a reverse flow head or had ball stud rockers, very interesting. Thanks for doing this!

[@shelleyking8450]

Wait, WHAT? Australia got Valiant pickups? I want one too.

[@TAVOAu]

Yep! And we also kept the station wagon going until 1981.

[@scotcoon1186]

​@tavogarage7505 we still have them, now they're called an suv or minivan.

[@TAVOAu]

@@scotcoon1186 Talking Valiant Station Wagons. The US dropped them after the 66 model. Chrysler Aust developed our own for the 67 model onward. Those bloated bubbles called SUVs are all over Aust too.

[@aussieausdeutschland4245]

And a Panel van version of the Ute too mate, just not that model.

[@TAVOAu]

@@aussieausdeutschland4245 Correct. CL model only. Late 1976 to mid 1978.

Aussie Challenger with the Hemi6 running 6 Webbers.🥰 Love that ute! Man I miss my 78 El Camino.😔

[@MrTurk6988]

We have the slant 6.... this is a first for me....

[@larryschmidt977]

the design of the valve cover looks a lot like the 6cyl AMC engine

[@aussieausdeutschland4245]

The AMC/Jeep inline 6 do look remarkably similar to the Chrysler Hemi 6, which makes me wonder if Chrysler sold that engine design to be used under license to them?

[@larryschmidt977]

Ya know that's a good question because that design engine has been in the Jeeps since way back , but Ive never seen one of the original Jeep engines before AMC got them back when it was....what Keiser or something like that@@aussieausdeutschland4245

[@johnrebus1641]

Its amazing how well designed the head is for a late 60's design. Holden should have looked long & hard at these before it bodged the Blue motor head in 1980. It's hard to understand why GM stuck to 1950's rubbish heads until the 90's, with stupid side by side exhaust ports & filthy wedge chambers. Nice to see the reluctor in the distributor for electronic ignition in a 1976 engine - 4 years ahead of Holden & 5 ahead of the Falcon.

[@aussieausdeutschland4245]

Ahh yes but the Ford 6 went cross flow in 76, and that was a huge improvement over the old 250 logger head

[@buffdelcampo]

Good to see the inside of the head. Thank you!

[@timkis64]

i knew ford had aussie only engines & heads.but never considered the aussie chrysler divisions offerings. very interesting, thanks for the insight.

[@mauriceholder1386]

Tony says he wont use power tools to disassemble or assemble an engine bc he wants to feel how every bolt pulls out and goes back in so he does it by hand. I see you do the same, im guessing for the same reasons. I see so many chanels blow a motor apart with power tools, its nice to see someone take the time do do something by hand.

[@NathansMoparGarage]

That is a cool engine. Thanks for sharing.

[@garryhatchett775]

Thanks for the info. Is the bell housing bolt pattern exclusive to that engine or is it common to another Chrysler engine family?

[@TAVOAu]

It closely resembles the small block V8 pattern, but different enough to not be a direct bolt in. A very small number of blocks were cast and machined differently, and accept the small block transmission directly. These happened when a shortage of the Borg Warner transmission led to Chrysler building a number of cars with 904 and 727 TorqueFlites. See my other video, "So you want to swap an Australian Hemi 6 into your US A body" I've tried to cover it there. Cheers.

[@ldnwholesale8552]

Many cop cars had Torqueflites, CH and some CJ 6s as well@@TAVOAu

[@JosephCowen-fz8vj]

Every Hemi Six can bolt to a LA engine box bellhousing , it's just the Six Bellhousing has the starter half way up on the side , I also had a 360 V8 with a manual 4 speed D20 Single Rail Borg Warner , it's Bellhousing had both six starter position and LA V8 starter cast on the one bellhousing .

[@shanew.williams]

A clever play on the name "Hemi" i must admit. The spherical combustion chamber of your 6 does rather closely mirror the classic Chrysler 318 "Poly" but by design, the true "Hemi" V8 engines of old have/had a central positioned spark plug to take advantage of intake & exhaust mounted OPPOSITE each other (across the head). Of course your cylinder head features the typical "side by side" valve arrangement of the Wedge head (and Poly).

[@TAVOAu]

But the bottom line is, that the shape is hemispherical, as in a slice off a circle. A polyshere is made up of flat surfaces, hence the name of the poly V8. So down to fine technicalities, the Hemi name is correct. The old V8 Hemis are only named such, due to the shape, and as you say, Chrysler exploited the shape by giving it those other advantages.

[@davef.2329]

Nice, very serviceable engine. Wonder what politics prevailed at the time that kept us here in the States from access to those Valiant, car/truck vehicles? They likely would have sold like hotcakes here. I definitely would have bought one, or more...

[@al_dente4777]

I too, if they would have been cast with cross-flow heads. TAVO's describing the inherent stamped rocker breakage along with poor quality headbolts is quite a dissapointment, given that the last thing an Australian owner would want to deal with is a breakdown somwhere in the remote Outback. Given the only one-barreled carburetor and the single exhaust extractor, the only visible advantage to this combustion chamber design is its improved efficiency of which benefits mainly cleaner exhaust emissions

[@BigJakesGarage]

I hear dodge will be remaking an inline 6 agin it be cool if they named it the “Hemi six” and marketed it like that.

[@TAVOAu]

I believe they've already named that the Hurricane 6

[@bishopcorva]

It's a fair shame that I6 engines weren't as popular here in the US. Seeing the ones that were in other markets, not to mention the vehicles as well for those markets kind makes one want to squint in irritation. Of course the same could be said for things that were effectively US only that folks from elsewhere would have given a toe or more for. Still though, that's one interesting looking piece for sure there guy.

[@davidbeard7842]

Love the rooster

[@thisisyourcaptainspeaking2259]

I'm guessing the Aussie market received better designs. Ford did the same.

[@aussieausdeutschland4245]

Yes we did

[@andyharman3022]

Calling it a Hemi was definitely stretching the truth. But if they had called it the "Cant 6" people wouldn't have bought it.

[@larryschmidt977]

how many main bearings does that hemi have?

[@TAVOAu]

7 There's a part 2 showing the bottom end.

[@ldnwholesale8552]

The correct amount,,7 unlike a slopey.

[@SLJ2137694]

Still don’t see why they call it a HEMI. Sounds like marketing talk to me!

[@TAVOAu]

Yeah, 80% marketing, 20% on its way to being a true Hemi. It's slightly domed and the valves are canted.

[@clutchkicker392ison5]

I'd like to watch but that camera shake is doin me head in . Sorry

[@TAVOAu]

Yeah, big mistake using a head mounted camera, with lots of bolt spinning. I'm learning and now using a tripod mount as much as possible. Sorry about the head!

[@TAVOAu]

Thanks for your feedback. This was my first attempt at making a video, and thought that the head mount camera would be the way to go. Not accounting for the body movement. Sorry you couldn't watch it through.

[@soloperformer5598]

What's a "Hemi"?

[@JosephCowen-fz8vj]

Any engine with a half sphere ( sometimes less for compression like this six it has 35 percent of a sphere ) for its combustion chamber , the plug absolutely does not have the come down from the top , a shovel Harley Davidson motor is a Hemi and the plug comes in from the side so does the Ford 427 Cammer V8 , and it also don't need to be a cross flow , the Valves in this Hemi are tilted front to back of the engine at 18 degrees , if you get a chance to look at pushrods they form a V from the cam .

[@mschiffel1]

Doesn't look like much of a HEMI to me.

[@jamest.5001]

Not much hemi about it is there,

[@JosephCowen-fz8vj]

Again only those who don't know what Hemi means say that , By definition Hemispherical means a a slice of a Sphere up to 50 percent , this chamber is 35 percent of a Sphere a 426 Hemi is 43.7 percent of a Sphere , the plug location has nothing to to with it being a Hemi , a Shovel Head Harley Davidson is a Hemi and it's plug comes in from the side , so does the plug on a Ford 427 Cammer motor it's also a Hemi , the Valves are tilted front and back at 18 degrees and the push rods form a V from the cam reflecting this , a 426 Hemi the valves are tilted left to right at 44 degrees , the six's front to back arrangement allows a non cross flow head that this is , and also has nothing to do with being a Hemi . All Hemi means is up to Half Sphere combustion chamber. No Hemi is ever half a sphere as it just would not work chamber is too big ,

[@ThirteenTwentyRepair]

I’ve looked for a Hemi/6 here in California for awhile. I found a couple in L.A. but they were not for sale. I’d love to port a 245 head with 2.08/1.60 valves and slap it on a 265 bottom end with a small turbo. Should have no problem making 550hp.

[@JosephCowen-fz8vj]

The 215 Hemi Six is the Smallest chamber , try that one , it was the 3 5 litre then the 245 at 4.0 litre and 265 at 4.3 litre , there are Aussie company's making forged stroker cranks to take the 265 ci out to 302 ci or more .

[@ThirteenTwentyRepair]

14:25 generous amount of unshrouding around the valves 👍🏼

[@brucegrunewald8423]

I think better lighting would make the most improvement to the videos. Very good for a first time effort - congrats!

[@TAVOAu]

Thanks for the comment and advice. Yes, just working with the very basics, I need to invest in some portable lighting and decent cameras, if I plan to keep making content. Cheers.

[@ldnwholesale8552]

Blown stove gasket and exhaust gasket, typical Valiant. The manifold will IF you can split them milling to make them square again.

[@vintagesawyer6246]

So if that "vertical " six fits under the hood , why was the slant motor needed? Or is the hood on that Ute higher than a Valiant ?

[@111000100101001]

I think the real reason for a slant design was because the engineer was loaded.;)

[@TAVOAu]

Slant 6 is taller, having a much longer stroke (in 225 form at least) See the link in the video description, Tony explains the slant there. The ute shown, is heavily based on the US 1967 on Valiant, and has the same hood height. Thanks for your comment.

[@vintagesawyer6246]

@tavogarage7505 Thanks. I love those old Utes and Wagons. Seen a few Fletch's show . First car I ever drove was a 63 Valiant 170 slant with push button auto. 4 door. Dad also had a 2 door convertible 3 in the tree.

[@johnrebus1641]

The Hemi 6 has a much shorter 3.68" stroke than the 225's 4.125". I've only driven a couple of 245's but they didn't seem to have the same low end grunt the 225 had, esp 160HP 2bbl version. Perhaps that glorious inlet manifold on the slant helped the long stroke too. I bet the Slant 6 has more even mixture distribution than the Hemi 6.

[@neilfromclearwaterfl81]

@@johnrebus1641 The Slant or Wedge 6 had its place and it did allow for a lower hood line than the GM and Ford offerings at the time. You put them side by side with the others and that slightly thinner front fender line became more apparent. Without the slant with the 225 with its long stroke would have needed a taller hood or to be dropped too close to the ground. The 225 did have enough grunt to work even in a Power Wagon pushing a snow plow and many made it to 300,000 miles which was not that common in the 1960's. Best!

[@stuartphillips430]

Cheers dude. First time for me inside a valiant six.keen to see more.thanks.

[@recondrone6826]

Interesting... I see nothing really special other than the Hemi stickers on the breathers.

[@JosephCowen-fz8vj]

Again please do some research before opening mouth , the definition of Hemi in engine terms it up to half a sphere , no engine is a full half sphere combustion chamber as its to big , the six has a 35 percent of a sphere chamber a 426 Hemi has 43.7 percent of a sphere chamber , the valves are tilted front to back at 18 degrees in the six and a 426 Hemi they are tilted left to right at 44 degrees , the six,s push rods form a V from the cam , the front back tilting of the valves allow a non cross flow arrangement, again nothing to do with it being a Hemi nor does the spark plug comming in from the side , a Harley Davidson Shovel Motor is a Hemi and the plug comes in from the side , so does the Ford 427 Cammer and it's also a Hemi , as far as nothing Special this engine held a record in the 1970s as the most powerful NA inline production six at 302 HP standard ( on the chassis Dyno it always produced more than that at the wheels ) , it was as fast in a Charger as a 351 ci Cleveland 4V in a Falcon , Chrysler tryed a 360 and even a 340 V8 in the same car , they were duds , slower , heavier and used more fuel , the Top Performance Charger Motor was this Six not a V8 , factory triple side draught 45 mm Weber carbies and tuned length headers off the factory floor 302 HP.

[@7s29]

Nice work. 👍

[@maceurbi2842]

Nice video "mate"! Do those use the same 904 transmission and starter as a slant?

[@TAVOAu]

No unfortunately. The standard bell housing pattern is quite similar to the small block V8. During the mid 70s, a small number were cast with a slight variance, to accept the small block 904/727 directly. Standard fitment for an automatic, was a purpose built version of the Borg Warner 35 transmission.

[@rexmasters1541]

Thats NOT a Hemi since the spark plug is NOT located between the valves.
