Another valve setting question........curious

[buzzinhalfdozen]

Mike I agree 100%. What works in 1 case may not in another. It's like saying everyone runs 90 square jets and 40 degrees of timing, works on some but not all. Joe

You guys need a P & G valve gapper tool, the old timers will remember

Remember this? I guess when a tool came in a wooden box...it's OLD!!!

SAE was who came up with the "how to" on setting valves. Seems to be more accurate when you set them this way.

Watched dad win $$$ setting valves this way/

Go the the Pro Stock pits immmediately after a round of qualifying, walk over to your favorite Team's trailer/pit and watch them check their valve lash, one cylinder at a time, using the EO/IC method.

The object is to make sure the cam lobe is on the base circle

Setting the intake valve when the exhaust is openings assures that the cylinder is at the beginning of the exhaust stroke and it's intake lobe is closed and on the base circle.
Setting the exhaust valve when the intake is closing assures that the cylinder is at the end of the intake stroke and it's exhaust valve is closed and on the base circle.
I have found this works on every four stroke engine from a Briggs &Stratton to blown hemi.regardless of the camshaft used.
I know a lot of guys use the "Mopar hood sticker method" but Keep in mind that most modern camshafts have more duration & overlap than those 70's Mopar cams.

On a fresh setting I always set the intakes first by watching the ex. pushrod just start to lift. That way you are always assured that when you are watching the intake close (because it is already set) you are really watching it go to the correct part of the lobe to be in the right place to set the ex. I also follow the firing order. You only have to rotate the crank 1/4 of a turn to be in the correct place for the next, in the firing order, cylinder. The 1/4 turn works for both intake and ex.
As stated earlier, be very careful about setting valves with the lifter off or past the base circle. If you do you had better "Know Your Cam Lobe"
Ed you have a PM
