Not enough of the folks left, that actually lived and drove with these engines. The ones still around, are getting on in our years, and forgetting a lot of the little quirks of specific engines, until we are blessed enough to come across someone with problems like this. Makes the memories come back fast. You will play hell chasing stuff all over the interweb, and never find that one hidden and forgotten quirk that finally fixes it. It takes the grumpy, ornery, old man to educate the interweb experts.
"An engine is an engine" is something I say often. It's true until you get into the details. The average guy can assemble any engine. The truly neurotic, obsessive, unrelenting attention to detail is needed for these "exotic" engines. Luckily, Uncle Tony is that guy. Man, I'd love to see UT build a hemi and beat on it like it ows him money.
It's the specifics that makes a master. I'm still 20 years on with 80s and specifically Mopar EEKs, and I'm still learning quirks. I've also archived about a dozen of pre 95' turbo Dodge specific websites. I don't trust digital. Some shit, the link is so old is was never trawled. AOL95 dial up shit
I knew that the Hemi engine was different. But I had no idea how different. You really need to build one for the channel. A series of videos on the build.
If you reverse the clevis pin on the brake booster and put a hairpin clip facing the inner fender makes it easy to remove the booster and master cylinder to the side, makes it easy also to change the #7 plug.
Well this is cool. I've heard a lot about the hemi but I've never watched anything about it. Just watched a teardown video on the newer 6.2 ford with the 16 spark plugs and one of the comments mentioned that there was similar architecture to the 426 hemi. Those great big valve covers look similar to me! Another comment mentioned similarities to the Ford 427 cammer. I just bought a 2012 with the 6.2 so it's really cool to learn about the heritage of the engine.
folks say "ground with too much advance" but it's really "drilled with too much advance" i.e., it's the rotational position of the cam bolt holes and dowel pin relative to the ground lobes, really, that is influencing that.
I’m 68 years old and I knew several friends who are not with us anymore that owned Hemi cars and they very seldom ran right but when they did they would put you in the seat.
So glad i found this channel. Did my apprenticeship in the 80s and 90s on datsun and nissans in Australia. Rebuilt a lot of engines did all the old school stuff. I have a lot of watching to do seen a few episodes and I know I'll love it great stuff
I work on a 69 Hemi Roadrunner once that had pertronix ignition, and that was the problem, the distributor was an original dual-point with the conversion kit in it, the problem was is that the pick up would go out of phase with the vacuum Advanced hooked up, the new style pertronix relies upon the points lobe as the reluctor and it just doesn't work properly
Those engines were originally designed for serious NASCAR racers and need to be set up , adjusted and percicely tuned because they are not forgiving like most passenger car engines. They run great for the people that know them inside out but most back yard guys need some tips to get the most out of them and keep them togeather .
I only use sealer or gasket shellac on the side of the gasket that sticks to the removable side, so like the covers will come off with the gasket stuck to it not the head...
Thanks Unk. Very interesting. On the timing of the #6 rockers. It seems to me you could get a ball park idea by setting equal lash amounts at tdc on the valves and comparing their closure with crank rotation
When ever a customer brought their Datsun into my old work with driveability issues due to tune, the first thing checked was cam timing, especially if head had been removed at any time. 7/10 would be wrong.
Put silicone on the gasket surface. Smooth it out and keep it thin and even. Then let it dry. You can then take the valve cover on and off and it won’t leak.
@@Cstoreri sad but true, another sad reality is that this car will probably be driven only 20-30 miles a year with half the miles going on and off a trailer.
No, that motor should come out and not only gone through but also a correct solid lifter cam installed for period correctness. I know I wouldn't have any confidence in the build after seeing what I see there.
Uhh tony.. My amc 360 valve covers were sealed with rtv by someone.. and a simple rubber mallet bang it wouldnt come off.. i had to pry every corner with my screw driver.. bending the cover to get it off.... so this csn happen to normal sized valve covers
The solid lifter intake pushrods are 0.282" longer than the hydraulic lifter intake pushrods and the solid lifter exhaust pushrods are 0.281" longer than the hydraulic lifter exhaust pushrods. Sometimes they'll work, sometimes they'll throw the geometry off a bit. I wonder which pushrods are installed with these hydraulic lifters.
I'll add to that. They used the solid lifter narrow pad rockers in this engine. Hydraulic lifter engines don't give the tip of the rockers any breathing room to re-center themselves , which is why Chrysler went to the wide pad rockers in 70 along with the shorter pushrods. I looked to see if there were any blue marks on the pushrod cups, which would indicate contact with the bottom of the rockers, and didn't see anything.
@@UncleTonysGarage Yes, but the large pad rockers also became the service replacements for the solid lifter engines, using the solid lifter pushrods. The length of the pushrods goes with the type of lifter, not with the type of rocker arms. The pushrods for the hydraulic lifter 340 T/A are also shorter than the solid lifter 273 pushrods. The 340 T/A pushrods are 0.266" shorter than the 273 pushrods.
There's no detriment to using wide pad rockers on a solid lifter engine, but there is one in using narrow pad on a hydraulic. As for pushrod length, I no longer have any Hemi rockers in my possession to make comparisons with, but I'm pretty sure the reason for length difference has more to do with the rocker than the lifters.
@@UncleTonysGarage The pushrod length is different for the lifter type. Even the B and RB specified pushrod lengths for adjustable rockers are different for hydraulic and solid lifters, with hydraulic lifters always calling for shorter pushrods. With the big blocks, that don't have the offset lifter angle the small blocks have, the length difference is also 0.281".
@@mromatic17 nice choice man. For a truck? Mine is 74-76 F-250 4x4 longbed sitting on like 36 inch super swaper tsl’s 🤘oh! And its gotta be a manual. 4speed.
@@New_Jax_City nice i'd love a highboy! my grandpa had a 1976 f-250 4x4 360 4 speed but sold it in like 2005 i think. I should've bought it. I wasn't super into old trucks back then but today I'd kill for it.
Sounds like the lifters are shot. Probably the last guy over tightened the adjustments to make up for lifter rattle. What a shame that a car with THAT much effort put into it, didn't get normal engine treatment.
that will do it...!....check the mechical advance in the disturbertor ...just incase there frozen ...seen that alought...!..beutiful car,,,wow...wwwway outa my price range...plus like u said...were could u drive a car like that...?
The well of knowledge about these engines is small, and shrinks daily...these little issues are why I wouldn't spend a dime on old, worn OE hemi stuff. I hope that there is still a old pro around to teach me a few things when I'm screwing my 528 together...this would be a very expensive learning curve.
Just some advice, take for what it is worth, no biggie either way, Pitch them champion plugs, they are junk!!! Always have been... Will cure alot of issues also...

He actually did a rebuild on a 426 GTX about a year ago, it's a great series,dig around you can probably find it

Uncle Tony is my favorite Uncle!
He’s way better than Uncle Touchy
Isn't it Ralph that has the blown 440 Roadrunner?
Good Lord, that car made me tingle, lol!
It sure seems to be a common theme among really nice looking Hemi cars that the engine has been poorly assembled.
I hope he buys you a big rib steak like Fred Flinstone. You deserve it. The world will be lost without that kind of knowledge. Great content again.
Another amazing tech vid from UTG!👍

Just in case anyone was wondering early hemi dodge desoto Chrysler also don’t use the spark plug washers
the knowledge Tony has just blows me away...
I’m 68 years old and I knew several friends who are not with us anymore that owned Hemi cars and they very seldom ran right but when they did they would put you in the seat.
I learned something! And I got many things from that! Thanks.
Ah my goodness what a nice shop thanks Ralph and UTG if anyone can be a Mopar Whisperer you are on the right channel.👍
Looking forward to that test drive.
So glad i found this channel.
Did my apprenticeship in the 80s and 90s on datsun and nissans in Australia. Rebuilt a lot of engines did all the old school stuff. I have a lot of watching to do seen a few episodes and I know I'll love it great stuff
So much knowledge in that head of yours, thanks for sharing
This is by far the most technical ive seen Tony get on an engine. Nice
If I were going to buy this then the engine is coming out.
There's not one hope in hell I trust the builder of that Hemi.
Outstanding!!
That was a nice red Sebring behind you guys.... Oop my bad it's a 98+ Camaro😂... Fourth Gen guys hate me!
Always loved the R/T over the super bee in 68. The taillights....
But I have a special place in my heart, my 70!!!
Not only the valve cover, but the number 8 plug too. I had a 66 Coronet 500 with a HEMI.
What a great collection of cars!!!!! Wow
I work on a 69 Hemi Roadrunner once that had pertronix ignition, and that was the problem, the distributor was an original dual-point with the conversion kit in it, the problem was is that the pick up would go out of phase with the vacuum Advanced hooked up, the new style pertronix relies upon the points lobe as the reluctor and it just doesn't work properly
Looking forward to that ride.
Never knew that about the spark plugs in the slant six must go and change mine 👍
Thanks for the lesson on hemis, Uncle Tony. I'd like to see more on the hemi and its quirks.
Those engines were originally designed for serious NASCAR racers and need to be set up , adjusted and percicely tuned because they are not forgiving like most passenger car engines. They run great for the people that know them inside out but most back yard guys need some tips to get the most out of them and keep them togeather .
Dude!!! That's so exciting that you diagnosed the problems of that hemi!!! Now don't f/u The paint up!!! Lol!!!✌️
I only use sealer or gasket shellac on the side of the gasket that sticks to the removable side, so like the covers will come off with the gasket stuck to it not the head...
Wow《☆》👍🏾🍺🤳My guess would have been the janky Fuel Pressure Regulator Uncle Tony showed us on the last Video✌😎☯️
A friend of mine has a couple of HEMI's it pays to know the right people when Building a Hemi Engine, he knew a few Super Stock and Street Racers too.
again: super-interessting!
Thank you Tony!
I thought at first that it may have the super rare potato in exhaust option
Good old streetside classics up on the hill in lavergne Tennessee
Just up the hill a little bit from the Volvo dealer up in the industrial park.
Great detective work Uncle Tony!

Interesting stuff. It is only "boots on the ground" that will tell you these things.
Put silicone on the gasket surface. Smooth it out and keep it thin and even. Then let it dry. You can then take the valve cover on and off and it won’t leak.
It might be nice to see the "cam card". just an idea. Also on early 392 hemi, Donovan made a hardened exhaust rocker arm. fyi
Is that color butter cup ? That is a absolute beautiful car.
Cool video Tony. Thanks!
Are there supposed to be washers on the rockerstand hold-down bolts?
Is anyone intending to use more than 300rpm getting it on and off the trailer?
What model was the green car that drove by?
Uncle Tony too the rescue 😊
Well done sirs! .. hopefully it fixes the issues. I hope there's nothing deeper. Good vid UT
Good Luck to You Sir.
Uncle Tony, shouldn't the heater hoses cross, i have a 67 hemi and they cross according to the manual.
UT, isn't that rocker screw issue the same thing that was wrong with that Daytona you tested in Cars Illustrated back in the day?
Nice work UT
For the amount of money that car is going for they need to replace that rocker and check the rest of them.
But we know the the reality… dealers will do as little as possible to move a car down the road!
@@Cstoreri sad but true, another sad reality is that this car will probably be driven only 20-30 miles a year with half the miles going on and off a trailer.
Hemis we’re notorious for that, it needs a set of properly fitted rockers, the machine shop should’ve done that.
@@alanmeyers3957machine shops quite often aren't the ones who assemble engines, they likely didn't have the rocker assembly at their machine shop.
No, that motor should come out and not only gone through but also a correct solid lifter cam installed for period correctness. I know I wouldn't have any confidence in the build after seeing what I see there.

I have seen that on some fords and some sbc. Shame too, cause it really makes a relatively easy job, suck.
I would also check for a restricted exhaust.
We most definitely learnt somethin outta dat
5:58 is that thing knocking?!?!?!?!
or was that just an exhaust leak???
Is this the same Coronet for sale on Dolphin (Maple) Motors :P
Let’s do a community poll to see if you should buy this
do you remember ,
Hustle Stuff ,
chop sticks ?
Ralph Rochhhhhhhha with the 10 second blown rv 440 with valve job
This reminds me why the Hemi is really only for hardcore racing. Too much complexity for just your average street engine.
The devil is in the details !
