    I have a 340 with a bullet solid lift roller camshaft.I need some help with valve lash adjustment procedure.I am setting the valve lash at .016 cold.This is how i am going to adjust them with the info i have gathered. Doing one cylinder at a time.With lets say number 1 cylinder intake valve is closed rotate engine till exhaust valve is half way open adjust intake valve to .016.
    Continue to rotate engine to exhaust valve closes keep rotating engine till intake valve is all the way open and just starts to close then adjust exhaust valve to .016.If this is the correct way how can i get each exhaust and intake valve in the same position when i adjust them.Maybe by using a timing tape on the balancer.

    Your procedure is correct, but I do not understand what you are asking. If you are asking if they will end up the same valve lash, the answer is yes.

    Here is the method I use. No need for marking the balancer, cam is on base circle of the valve you are adjusting if adjusted this way.

    EO/IC rule (Exhaust Opening and Intake Closing). Set the intake valve lash when the exhaust valve is beginning to open. This will put the intake lifter at the base circle which is where you want it to be. Then set the exhaust valve lash when the intake valve is about halfway down on the closing side.

      there used to be DC sticker for under the hood which showed you what valves to set at the same time. It saved a lot of bumping the crank over. Perhaps, somebody could post a pic.

        This is the easiest way to do it, as far as I'm concerned:

          EOIC. all you need to remember. You can use this on a 1 cylinder briggs or a V10, V12, or V16 as long as it has a cam and rockers. And you don't need to know the firing order. Your chart will do you no good on Chivvies or Ferds with modified firing orders.

          Having said that, "if you have the chart" that's OK too

            To answer steven190.I wanted to mark the balancer when i have the exhaust valve when its half way down as it is opening i can set intake lash.Also need to mark the balancer when the intake valve is just starting to close or start upward so i can set valve lash on exhaust.If i have a cylinder on top dead center as i rotate the engine 90 degrees i think that would be half way to its full open position on the exhaust valve.Then when intake goes downward or opens and starts back up i believe should be about 180 degrees after tdc. When you rotate the engine 360 degrees from tdc does that move the exhaust valve fully open then fully closed then the next revolution of 360 degrees opens the intake fully open and closed.I know i am probably confusing you trying to explain the best i can.Thanks

            I used to use the MP chart too, still have the sticker under my hood, works good also. The EIOC meathod is just easier IMO.

              well, who really cares if the chart won't work on some crappy Chevrolets or Fords? The chart is for our stock or stock-ish B & RB motors, LA motors, even 360 Magnums. And believe it or not it'll work on traditional Chevy Mouse and Rat motors too!

              I know what it works on. Believe it or not I've put together a couple of Shivvies and a Ford here and there. And a reverse rotation Y block marine Ford.

              YOU might care if you are trying to help a friend out with an "alternative engine", just pointing that out. What if you don't know this and your chart gets damaged? You backfire the carb, etc, or "steam" it off with a radiator "event?" Your chart goes away, and there you sit, ??hmmmm??

              I guess you didn't notice the part where I mentioned...........

              THE CHART is the easiest way to go on any engine with a 1 8 4 3 6 5 7 2 firing order, unless you enjoy rotating the crank more. mark the damper at 90 degrees, 180 degrees, and 270. if you are worried about steam or other shit, write the chart on your garage wall. I have adjusted my valves in the staging lanes at the strip during the 1 hour lunch

                I just bump the starter relay with a wrench and adjust the ones with closed valves and write it down. A few minutes later and done.

                heck, just about everyone nowadays has a smartphone. Save it on your phone.
