Thanks man! I appreciate that

At 4:00 into the video, the author stops the crankshaft at # 1 cylinder TDC on the compression stroke. Then he begins to adjust both intake and exhaust valve rocker arms. This is correct for # 1 cylinder! At 6:39 into the video, this where I do things a bit differently. I rotate the crankshaft 90 degrees, and then adjust the rocker arms for the next cylinder in the firing order, of which is # 8 cylinder for the SBC. Next, I rotate the crankshaft another 90 degrees, of which allows for the adjustment of # 4 cylinder rocker arms. You will continue right down the firing order..... 1-8-4-3-6-5-7-2. This is known as the 8 stop static procedure, and is Goof-Proof. Keep in mind that we are setting the depth of the hydraulic plunger..... we are not adjusting valves. By the way, doing this prior to the installation of the intake manifold (as he is doing), and prior to the cam followers having oil in them, we have the opertunity to view the top of the plungers as they begin to move downward. In other words, we can actually watch the plunger begin to move downward after ZERO lash has been established. The average SBC hydraulic cam follower plunger offers approximately .080" to .100" of travel. This will vary from manufacture to manufacture. The goal is to set the plunger into the cam follower body by approx 40% to 50% of it's total travel. Rocker arm stud thread pitch Xs rocker arm ratio (1:1.5) Xs nut rotation, gives of this dimension. NOTE: for a high performance camshaft, you may want to use the manufacture's spec sheet and a degree wheel, in order to make this adjustment during exact bottom of base circle.

Great video. Very informative. Thanks

I have set my valves similar to that. I would find TDC and set the valves on #1 cylinder, then rotate balancer 90 degrees and set the valves on the #8 cylinder, all I do is follow the firing order and set the valves every 90 degrees

Rebuilt motor Im glad I was able to start my engine without proper torque now I only need adjustments . For corrections

Keep.up the good work

Thank you I appreciate that

Lifter preload is to hide manufacturer inconsistency and or take the human equation out of the assembly process. Basically, it's for keeping quality control without having to have skilled assembly workers. Preload will be a problem in a performance application when you are running high rpm. If a valve floats at all, the lifter will take up the slack and then the valve doesn't close.

With your manifold on can you just feel push rod go down on intake and feel for air, I'm going to re check my valve train after its been rebuilt a bit ago

Easy with adjustable rockers

Stock or not, always adust intake, then the exhaust, on separate rotations. You adjust the lifter on the OPPOSITE order of fire from the one that is FULLY OPEN. That is the ONLY WAY you can be on the very back of the lobe on the base circle. With #1 intake fully open, adjust #6 intake 1/2 turn in from ZERO lash. 1 - 6 8 - 5 4 - 7 3 - 2 6 - 1 5 - 8 7 - 4 2 - 3

Hey Pat! I set my pushrods to o lash then half of turn. Runs fine, but there A slight ticking when running, really have to listen to hear it. Would you recommend tighting down another 1/4 turn. Comp 1.52 roller rockers Melling harden foot hydraulic lifters plus stock push rods. 😊

Engine off valve cover off, grab each rocker and wiggle it See if any feel abit loose If everything is correct than 1/2 a turn preload will work fine but you can go another 1/4 turn no problem, if you want Some cams are just abit noisy, no matter how you adjust the valve train

Question. Are your pushrods always able to spin?

EVERY single part needs to be thoroughly cleaned. Grit from machine work (the parts actual creation or recondition) will clog oil passages. 👍🏻

Question:. . 350 block 305 heads?..is there any mods that need to be addressed if anywhen going this route as far as pushrod length ,certain gaskets that need to be used ? Your expertise will be greatly appreciated.thanks in advance

305 heads on a 350 block is no problem. Pushrods should be the same or similar but will have to be checked just like any head swap. The head gaskets are determined by the bore size so 350 head gaskets will be used. Nothing really weird about putting 305 heads on a 350 but putting 350 heads on a 305 can be tricky as often times youll have valve to cylinder clearance issues with valves bigger than 1.94.

"Cylinder to cylinder" means you're spending more time turning the engine than adjusting the valves, but whatever floats your boat

Interesting. I have always followed the exhaust starting to open, set intake valve, intake closing set exhaust valve. I do this to ensure the valve being adjusted has the cam lobe on the base circle. Not saying either way is better, just my way is different. Never had any issues.

I pump up my lifters to make sure they work properly, you don't have to but 1st startup can be noisy if they're part filled so don't panic right away. If you do pump them up, some folks seem to over tighten them but it's never happened to me so I don't know how that happens. I pre-load about 0.020", which usually is about 1/2 turn. Can't see lifter pre-load if intake manifold's already installed.

@@cuttersperformance Absolutely, we must prime the oiling system! 100% agree. Several times I've replaced lifters without pumping them up and no priming of any kind, the lifters will make plenty of noise in this case. Priming probably would've eliminated most, if not all of this. I've also bought lifters which were pre-pumped with oil, I guess the factory actually tested leak-down. I've been pre-pumping them before install to test leak down rate since hearing of so many cam failures.
