2:39 Steve, I knew your explanation of pushrod length checking would be accurate yet easy to understand as well. I already knew the procedure quite well but getting your professional take on the subject was more than enough reason to watch. The sweet icing on the proverbial cake was the demonstration engine used. NOT A TYPICAL CHEVY, BUT A SET OF FORD MOTORSPORT “385 Series” HEADS 👌. Well done ole chum 🏁.
In an episode of Steve Tech please discuss calculating minimum oil pressure required to oil the rod bearings based on crank main diameter and engine RPM. I know increasing main diameter and/or RPM increases necessary oil pressure, but how to calculate minimum oil pressure required? Cross drilled mains add another element to consider. Thank you for the great content!
One of the best car channels ever.. really help me to grasp the concept of engine building the proper way..but totally underrated.. U should have 2.4M subscribers for sharing all the knowledge in details Anyway, keep up the good work and god bless u sir..
Finally see somebody doing it right with checking springs. There are scores(which is a lot) of videos on youtube of people pulling rocker to valve stem patterns on hydraulic cammed engines with their normal valve springs installed.
Hello Steve! Good to see you again sir. If you have an older cam and lifters, would you measure all of the pushrods? Cause lobe and lifters wear might give you different lenghts on your adjustable pushrod? In that case, buy a new cam and lifters? Thanks so much for sharing. Cheers and blessings from Motown/Dearborn
First LS Platform, LS7, solid roller. Once solid shaft mount geometry is correct then move to pushrod length. With there being lash needed in the valvetrain, would I take the length checker all the way to zero lash with minimal side to side lash and 0 preload, on the base circle, then subtract the lash needed from my overall length? Or alternatively just put my feeler gauge of lash required and take the pushrod length checker to zero lash? Thank you for your time! Hopefully I conveyed my question correctly.
Do you need to take into account the distance the length checker sits inside the cups of the lifter and rocker arm when getting a final measurement of your pushrods? It seems like adjusting a length checking tool out to where you’re happy and then using what amounts to essentially a precision flat edge on a pair of calipers to get a length could be inaccurate. Maybe I’m over thinking this.
wow this is blowing my mind, do you guy's need a old helper in he's 60's who still think tunnel rams carb motor is king...... I'm free no money just feed me your brain until me brain is fat.
Geeez Jerry! A little harsh there brother. Steve has forgot more about big time engine building then we will ever know, imo. What engines do you build sir, and for who?
It is all over the spectrum with different cam lifts and valve spring tensions but you can find out in your own engine. Use your torque wrench and sneak up on how much torque is required to just turn it over by hand. Convert ft pounds to horsepower. I believe it is horsepower hour. You have to decide if you want the spark plugs in or not.
Cant raise the stands for the shat on a LA small block mopar. So your instructions on shaft mounted rockers doesnt hold true. The shaft itself on a mopar is raised by using shims under the shaft, putting the shims on top of the stands which moves the rockers closer to the valve. From watching many of these videos on this subject, not one has addressed the world of mopar.

THANK YOU STEVE, GREAT VIDEO
Damn I'd like to work for you... You explain so well, look professional and damn you seem cool keep doing those great job and videos !

great video!
Jeez!! What tha hey??? A casket in the shop? Did you get a deal on a used one by chance? Dang fella!
Do you round up or down to get the nearest pushrod length?
I need to scan & download Steves brain.
So that big pushrod fit in the titanic that sank. While the smaller boats with smaller pushrods were still floating.

Girl's pushrod gets me to work every day and makes me money. That man's pushrod just cost a bunch of money.
I see that gen 4 Viper intake .
Nice. #!!! 😊
Those "mans pushrods" should be called "drum sticks" for obvious reasons.

Big block ford
You talk much and say nothing!!!!!!!!!!!!!!!!😢

What is the power required to rotate a push rod valve train?
