My grandmother (92 years old) heard Steve talking about "valve movement" and thought he was saying "bowel movement" and was wondering if he was having trouble with it lol I almost died, shorted out my keyboard with tears from laughing so hard. Poor granny..
At half sweep or half lift I set mine perpendicular to the valve centerline, whereas if I draw an imaginary line through the center of the fulcrum and the tip that line should be exactly perpendicular to the valve. That will be the longest point from the fulcrum to where the roller tip touches the valve. Similar to the dwell point at TDC, from that point up or down your moving back. From there to zero lift or full lift will set your contact patch width. If your patch is not centered you now know the contact patch width and can calculate how much offset you need for your stands. All the videos where guys show this make it look so complicated, if you draw it on paper you really start to see how simple it is, elementary school geometry.
Poor dog must not like Fords. One minute he's behind Steve working on a Ford and he's looking bummed. Next minute he's out venting his frustrations on some unsuspecting rube.
Ever see the part in the cartoon movie Shrek? When he walked into the city and notices the bigger then everything buildings. The next line he has is directly to boost and those manly push rods.
Always look forward to seeing you (and Kyle's) videos. You explain the science, geometry, and physics of it all in the simplest of layman's terms. Some may say that this much attention to detail doesn't really matter but it really does. Keep em coming. 💯 👌🏼🇬🇺
I love watching your videos, especially the sense of humor you have. You and Tim McAmis would be a great pair to tell us how not to do stupid crap. Lol
Hello Stéve, love your channel. Have you ever considered Jesel‘s rocker arm sweep, set up? What do you look for when setting roller geometry and sweep pattern? JESEL We set our aluminum systems with a low pivot geometry which results in the majority of the sweep pattern occurring while spring pressures are at their lower range. The majority of roller travel occurs from zero lash to half lift which results in minimum roller travel for the duration of lift when spring pressures are greatest. At zero lash, the roller should start approximately .050” behind the center of the valve stem, sweep across center and end near the center at full lift.
you do a good job of "practical" explanation... gives customers an idea of why a new build takes so friggen long and why it costs what it does.. Personally, I hate new stuff and especially so when they need it yesterday... Love the tapered pushrod.. We only ran .500 in the KB fuel motors.. But in all reality, the HP you are getting out of some of these promod motors is the same as a 20 year old fuel engine.. pretty amazing to see low 5's out of a door car of any kind...
I started using a piece of paper between the rocker and stem. It will mark itself and show the sweep of the rocker. You will be able to see if the sweep is centered.
I think it was the 94 Ilmor-Mercedes Indycar engine where they discovered that if they mounted the cam really high in the block and used a cam follower bottom rocker they could get away with using a 3 inch pushrod for a lessened valvetrain effort .. But really the main advantage was they could get away with running an extra 5psi of boost by running a 'stock block' , though what that engine had in common with any production engine is still not quite clear.
Does allison transmission make anything racers would be interested in I just landed a job there and want to know what to put in the lunchbox? Just kidding!
Funny how Jessel (in their instructions and setting tool) always had more sweep off the seat and others like T&D and yourself go with more of an even sweep. Danny said it was due to sideload with big springs and having less sweep when the spring forces were at their highest. I always went with even sweeps which always gave the narrowest pattern and most lift.
2:04, Mr Morris, you're the doctor. I think the pistons on the trophy in the background are upside down. Just an extremely important thought from someone with apparent OCD. LOL. I love what you're doing for motorsports!
Great video Steve. I build a lot of engines and mostly for street engines IMHO the stock length pushrods are fine but I always check them. The LS's I build I have found really respond to checking the valvetrain for wear and proper operation. Even the junkyard 5.3's get worn rockers replaced and a new set of one piece pushrods. I have an old roller tipped rocker and look for a centered contact patch on the valve tip with a .020" or so wide sweep pattern at .550" lift. I have had to go slightly longer but the biggest problem I've seen is reusing worn valve hardware. You LS guy's wonder what that ticking noise is, check that pushrod tip and rocker pushrod pocket seat.
You do not sell cheap shirts. And your shipping is reasonable as well. a lot of people I won’t order from cause shipping is way too much for just a shirt. Appreciate you!
Damn detailed explanation with an awesome camera person following you closely point to point💪, Steve does moving up the stand higher away from the bolted position make it more unstable at high rpm? And does the "manly" larger heavier pushrods make it easier for high rpm tendency for float , since titanium retainers were used to lighten valve train operation? I didn't ask that right, hope you understood 🤔👍
Man thanks for this video, as crazy as it sounds. I race lawnmowers,and run a tecumseh engine that has a stand set up.. only difference is my rockers arnt roller right now. But having a small problem with the tips wearing kinda funny.. I can take this info and see if I can fix this little issue I have. Thanks.
Very informative and straight forward. I noticed in this vid and others I have seen, there are numbers written on the gasket surface for the valve cover. What do they mean?
Those LS pushrods look less manly then Slant Six pushrods,... Steve, do roller rockers like that still get positive valve rotation to reduce wear at the valve head ?
I bought a square body pickup that had a nice 350 engine someone spent alot of money on it.Iron Eagle heads ARP head bolts Comp Cams valve train ect.Ran like crap valve ticks and taps.Come to find out it had 351 Ford push rods in it which was a shorter and you couldn't get the valves adjusted.Put a set of Chevy pushrods in it problem solved.
Push rods are cylinder shape, cylinders are even cylinder shape I never did understand why no ones tried making cylinder shaped connecting rods ? Do they have to be flat surfaced becuae of the crank ? I didn't want to ask this question sounding stupid but you have a cnc and love thinking outside the box just always wondered.
They would end up being too heavy for the job they need to do. They only need the strength in one direction for the most part, all the material on the sides (the typically skinny part) would be overkill. Also, like you mentioned they need to fit down into the crank and up into the piston so they would end up flat on the ends anyways.
Big, like container ships, have cylindrical connecting rods, and piston rods. The need for wrist pin, and crank pin bores on these car engines leaves very little room for a transition from a loop to a cylinder, so the most efficient and effective shape is what you see, though I don't doubt a hollow cylinder could be made to work, it would probably be cost prohibitive, and have trouble at the welds. Push rods only need to push and resist buckling. Con rods need to pull as well.
Just a thought. Would increasing the roller diameter on the rocker arm make the contact with the valve better? Then it would have good contact thru the arc. Thanks.
Not easy trying to explain sweep motion when making videos..how to set rocker hight and find out required pushrod length. Thanks for your time enjoy all your vids. MAKE A SHIRT PUSHROD LENGTH MATTERS.

Her flapper valve is worn out
By the sounds of things? 🤔

Haha Tonya Harding push rod had me cracking up 😂😂
Real knee slapper...
@@HighwayMike too soon . . .
Boost fixes everything, if it ain't broke, it can fix that too. 👌
I've never been one for looking at other mens pushrods, but you might have just converted me 🤣🤣
Let’s not go there😂

The Manley push rods in my sbc look just like your Girly push rods.

love the Dereck from VGG reference! Love your channel and content.
Thanks for all you vids Steve Morris . Would you do one on Cleetus’ refresh when you get it? Like you and all your motors , big time winners. Thanks
Yep will do
I'm really looking forward to seeing this. It should be fine but you never know.
This is what sets you apart from other channels. I love this stuff !
Love my All the Freedom shirt. Wish I needed a set of Tonya Harding push rods. But I don't. Dammit,!!
Thanks, Steve for showing me how to get my measuring technique down Now I wont start with my taint!! good deal!! i got an 1.5" Killing it

Steve thinking nitrous guys know how to read is pretty funny.
Thanks for this, Steve. As luck would have it I need to measure my pushrods and get them ordered.
The shirts are actually really nice i got a couple i like them
just ordered my shirt an cups love the content man
“Just do it, trust me” 👀 coffin on top of offices. Me: ok Steve, no problem 😅
I saw in Cleetus’ last video he is finally going to send you Mullet’s engine, can’t wait to see your video on the refresh of it.
My wife says i have a nice push rod!!!🤣🤣🤣🤣

Glad you like them!
I've bought a few of your shirts and the first thing I noticed is the quality is way better than most.
thanks
Dewey is the only one in the shop that can see ghosts, so cut him some slack. He's protecting all of you.
I love watching your videos, especially the sense of humor you have. You and Tim McAmis would be a great pair to tell us how not to do stupid crap. Lol
I have a very strong suspicion that you could not carry-on the manly pushrods when taking an airplane.

Smart a$$ lol,nitrous guy still saving for boost and hoops!,so forgive me if im not ready for a shirt
Custom engine building at it's finest. Thanks Steve.
Manton will make you pushrods to the .001. I order them all the time.
Awesome video Steve , thanks for sharing
The Tonya Harding Push Rod... 🤦🤦✊🤣🤣🤣🤣🤣🤣
So funny my dog started Barking 😊
Awesome video, you show us the correct and easy way to do it the
First time!
Thanks 👍
Every video of Steve Tech I learn how to build engines better. Thanks for all you do for the industry brother. 🇺🇸
Totally agree with you on how nice your shirts are! Love mine, especially love how long they are

It's all about geometry 👌 I love watching your tech videos Steve, the way you explain and demonstrate what you're doing makes it super easy to follow.
You need a "Methanol burns everything" T-Shirt too 😁
Or " i love meth"

Loved the “cup in hand” example discussion with the nitrous Buddy… mfriggin funny az fuk !!!!
I like how the dog really doesn't get more than 5 feet away from you!

3👍's up Steve Morris thank you for sharing
The Tonya bit was funny shit. Had to back up to watch what I missed while laughing
The red cup can also be used to take up a donation for your buddy's nitrous inflicted broken parts lol
I know Jesel has a tool for setting the stand height that they include in the kit.
Thanks Steve for the info. It was very helpful.
So cool to see Kyle following in your footsteps. I hope one of my kids has enough interest to learn the stuff I have to teach
thanks for sharing your valuable time and knowledge
The Tonya Harding!!! Takes a real man to handle lol!
Steve that’s so manly of a pushrod STROKING IT comes naturally!! 🤪
Ear phones on, I thought my dog was barking!
Thank you. Clear and understandable show and tell.
Great information. Much appreciated.
What is a good metal choice for your shims?
Steel
You do not sell cheap shirts. And your shipping is reasonable as well. a lot of people I won’t order from cause shipping is way too much for just a shirt. Appreciate you!
3:35 Those are some "10 year old girl" valve springs!!! LOL!!!
Hell yeah brother thank you
I would’ve cross threaded those bolts with the impact 1000%… very impressive
Lol love these videos
I was going to order a new SMX, but I refuse to do business with anyone that can't discipline their dog for filming. phht!
Are you going to clearance the pushrod holes in the head, or is the actual pushrod smaller than the checking pushrod?
Very entertaining and informative!
Gonna have to grab that bundle!
😁
Am I the only one that notices how the manly pushrod looks like a drumstick for a drum?
Thanks brother
Steve is a Riot 😂😂😂!
whoever made the intro didnt think about a car shifting from redline to 2,000 rpm lol
Damn detailed explanation with an awesome camera person following you closely point to point💪, Steve does moving up the stand higher away from the bolted position make it more unstable at high rpm? And does the "manly" larger heavier pushrods make it easier for high rpm tendency for float , since titanium retainers were used to lighten valve train operation?

another great vid sir, Man those Ferd heads look like they flow r they stock or have been loved on
Dewey doing Dewey things as always. Gotta love it. LOL On a more serious note, can you build a NPK rules compliant SMX that produces over 4500HP?
Yes
Amazing how much goes in building a awesome engine thanks for sharing your knowledge with us
your pushrod vs the pushrod she told you not to worry about

this guy just keeps pulling HP OUT OF HIS HAT a magic trick
Very informative and straight forward.
I noticed in this vid and others I have seen, there are numbers written on the gasket surface for the valve cover.
What do they mean?
Insane valve springs demand insane pushrods. The roller world has changed a whole lot of things.
To best see contact area use cheap red lipstick works everytime
Great tutorial.
That's the size of a caterpillar c13 injector pushrod lol.
Absolutely Feckin Awesome
Stroking the man's pushrod I see
At peak lift, you'd want the roller tip about centered?
Hay, what’s the dogs name?
…his name is ROOEUUU!
I’m sorry what was his name?
…his name is…ROOEUUU!!
Yea, what?
…ROOOEEUUUUU!!!
He has no etiquette.
Why do you have a casket in the background above the restroom?
That’s what I want to know?
Those LS pushrods look less manly then Slant Six pushrods,...

The more you know to the two blokes that took the time to explain and give understanding thank you I appreciate that. Learn something new every day.
That question made me think of cedar post for ceiling joist or rafters 🤷 that's just what popped in my head
Just a thought. Would increasing the roller diameter on the rocker arm make the contact with the valve better? Then it would have good contact thru the arc. Thanks.
I think the added weight from a larger roller would outweigh any benefit from the tiny increase in contact area
Steve, Does the roller center and the fulcrum center being 90 deg to the valve center line at 1/2 lift not apply anymore? Thanks
