This company makes great engines! Have one of their 383 strokers in my 69 Chevy C10 with a Edelbrock pro flo 4 EFI system and it runs great every time I drive it!
We did that one turn adjustment on our lifters and it ended up hanging the valves open and we had no compression, we ended up just going half turn and it worked
Yes you can just use EOIC..exhaust opening adjust intake...intake closing adjust exhaust it's easy brother just make sure your lash is out but not to tight
okay so that is with studded rockers, what about typical rocker stands with bolts, you turn it 1/2 turn, now it isnt tight so how do you tighten a ls rocker bolt without adding preload?
curious 7/16 bbc rocker studs , used in pontiacs when you want to run adjustable valve train. do you typically do more than 1/2 turn adjustments with hydr. lifters , say comp cam and crane for example? in your experience.
. Thanks for sharing this video… But I am wondering if it would be same way for classic Marine GM 350 opposite direction (RH rotation) or different method??
If your running a solid rail rocker set up yes. All ls motors from factory are set with a guide plate and use a 7.400 pushrod. 22ft pounds of torque on the bolts for rockers
Most of the time a tick is either a rocker or an exhaust leak, look at the manifold to head gasket and collector gasket and any flanges if you don’t see any black then adjust the rockers, make sure you do the procedure for an ls though I’m not sure if they are different
7/16 diameter rocker studs have a different thread pitch (course thread) than a 3/8" diameter rocker studs (fine thread) because of that difference in thread pitch, the distance the nut travels downward is less with the fine thread than the course thread. Results are, to get the same .080-.100" preload you have to turn the nut farther on the 3/8 stud than you would the 7/16" stud. Hope that helps you

You did a fantastic job explaining how to set valves
What if the engine isn't new and may oil in the lifter, I have an old build 302 and I believe it has roller lifters
when you did your one turn preload and then tightened the lock screw , you gave in another 1/8 turn to lock it didnt you just add more preload ?

VERY GOOD EXPLANATION. Thank you for that.
Great info! Can I use this same method if the engine is in the and has been running? Most videos show new builds.

How do you adjust the guide plates to align the roller tip on the valve? Also how do you check your rocker geometry?

So it doesn’t matter what stroke your on when the intake is opening, set the exhaust?
You call it ice. I go EOIC. Exhaust opening, Intake closing. Work out the same in the end
What does it do when you trim off the middle divider on the intake? How much do you take out?

Have your lifters been primed and bled?
What lifters are you using?
I just re did mine with this method.
Thanks for this video.Explained a lot and made it simple.
I get less than an 8th of a turn and the valve opens, what do i do
Are lifters primed ?
good vid...what do the OEM chev roller lifters use for plunger travel? i assume you are using those type in this demo??
I have an LS1 engine with that tick. Adjusting the rocker should remove that tick?

@@tannermcclellan3021 it's a stock engine with hydraulic lifters.

Ls is not adjustable. If that's the issue, you'll need to change pushrod length instead
Why does a bigger rocker arm stud take more preload?
7/16 diameter rocker studs have a different thread pitch (course thread) than a 3/8" diameter rocker studs (fine thread) because of that difference in thread pitch, the distance the nut travels downward is less with the fine thread than the course thread.

So by locking down the rocker you actually added almost an other 1/4 turn=
1 1/4 turns from zero lash after lockdown???????
I saw 45 degrees that's 1/8
@@rotorblade9508 almost 1 1/4
Okay 1 1/8 turns, regardless my BB Chev 396 roller cam and rockers would not run with that adjustment, I don't think 🤔
hey bro! does this technique works even if my lifters are full with oil? (I HAD TO INSTALL 2 NEW PUSHRODS)
Thanks for sharing
That seems like an awful lot of preload, I've only ever heard of half or three quarters of a turn?
I've done 1/2 turn for a long time
i do 5/8 then get the extra 1/8 from the "lockdown"
Agreed. 1 full turn is a lot
@@ironhorse127I got a Haynes manual and it says small block 1 full turn big block 3/4 Turns, I’ve always done 1/2 turn though
@@daredevildare3641ever had any issues with 1/2 turn? I’m adjusting my small block tomorrow I was gone do the 1/2 turn like you mentioned
sorry last post meant to say engine is in the car
20👍's up EG thank you for sharing 😅
Eoic
Too much preload...
He builds engines for a living....think he knows what he's doing....Jack ass
goodgreef
There's no such thing as a hydraulic rocker arm
Yes huh there is
Spin the pushrod. That wiggle the pushrod up and down is for amateurs.
Spin is inaccurate. I can spin a pushrod with preload. Cant wiggle the pushrod when preload is set!

Thanks for the video. Very informative and straight to the point.
