Isn't the hotrod world awesome? We all get to pick our own way of making things work for ourselves without anybody else being condecending about it or feeling THEIR way is the only way and that everybody else is doing it wrong.  Well, one thing is for sure, doing it in 110 degree is wrong - no matter how you do it. Been to the pavilions lately Dwayne? Hahaha... yeah, it's a bit warm out! The sweat running into my eyes takes some of the fun out of adjusting my valves. LOL The pavilions aren't much fun anymore. They run everybdy out of the parking lot about the time it might even begin to start cooling off. I don't know how some of those guys do it. They show up at noon, pull out their lawn chairs and bake. NO THANKS! I'm not setting foot on the place until it gets dark. Look to the right of the pic and you can see where my car has been for the last 3 months. See ya in the fall.

I never saw the logic of setting one valve according to what another valve is doing, but, whatever.
People that still use the EOIC method must like barring/bumping the motor over about 20 times to set valves when it can easily be done doing it in about 5-6 rotations.
I bring the #1 intake to fully open, then rotate the crank 1 turn, which leaves the #1 intake solidly on it's base circle. Set #1 intake. Rotate crank 90* - Set #8 intake. Rotate crank 90* - set #4 intake. Follow this pattern through firing order to set all intakes. Now bring #1 exhaust to fully open, then rotate crank 1 turn, which leaves the #1 exhaust solidly on it's base circle. Set #1 exhaust. Rotate crank 90* - set #8 exhaust. Again, follow pattern through firing order to set all the exhaust valves.
This works with EVERY canshaft, no matter lift, duration, lobe separation, or firing order, and sets the lash off of its cam lobe and not another one.
Pretty simple, HUH? How about the reason that according to the laws of physics, what one lobe is doing, TELLS you what the other lobe is doing. And your method seems anything BUT simple to me. That's a lot of crank turning, looking at marks and walking from side to side. I would imagine I could adjust my valves 4 times using the other method, before you got done with one this way. I have NEVER seen anything as brutally simple as valve adjustment, get as much play anywhere as it does on THIS board. Some seem to think it's like rocket science or something. You have to remember, you get 5 people together and tell them to set the SAME valve to .024, you likely get 5 different TRUE settings, because everybody's FEEL is different as to the drag on the feeler gauge. So is it .024 or is it a loose .024 or a tight .024........LOL!!!

It's VooDoo I tell ya just plain VooDoo
Ok at least on Moparts it is Voodoo. Flex is what you are seeing nothing more nothing less. Set things how you like. FWIW a "billet" STANDARD size cam core means nothing in terms of flex in a valvetrain. Could be your pushrods, the cam core, rockers, rockershafts or yes even that fancy cam is the spring load is high enough and the cam is a STD core size, yes even a billet. The reason for larger cam cores like 55, 60, 70 was to try and keep them from flexing under load.

Anyone use the Mopar Performance 90 degree method anymore? I do, but I'm not afraid to try different methods. My new build uses a solid roller so I think while it's on the stand with the intake off I'll try some different methods just to see how accurate they are. I'm no where near that point in the build yet though.

Anyone use the Mopar Performance 90 degree method anymore? "Anymore" would imply that you EVER used it, which I have not. Seemed like a waste of time to me the first time I ever saw it............LOL!!!

Anyone use the Mopar Performance 90 degree method anymore? I used it recently, at least I think so. I used the chart that came with my Hughes Camshaft. I followed the directions that came with it to a T to make sure I didn't wipe the cam, or that if the cam did wipe it hopefully wasn't my fault. I did it during the last angry thread about valve lash so was kind of worried about it. I didn't have the valley pan or intake on and can say the chart had me on the base circle like it should. I also paid attention to the rockers so I knew what to look for with the preferred EOIC as this was my first time with adjustable rockers. I think both methods would of netted me the same results for MY CAM.

Piston at TDC and add air. I use the hose from my compression tester (remove the schrader valve)...hooks right up to my air hose.

Tig welded this tool tonight( it´s nine a clock in Sweden) to remove valve springs.
Found two pieces of laser cut tabs.
Do I place the piston at BDC and add air pressure so the valves don't drop down?
Will need to cut a spark plug and weld on the air connection.
I guess I don't need much pressure to keep the valves staying up.
Piston at TDC. That way there is no chance of the valves falling in to the cylinders if they come unseated.
