I have found the sweet spot for max valve lash, but it´s with full lift on Ex. for Int. and vice versa for the Intake( Exh. at full lift).
It´s supposed to bee when ex opens, maybe about half lift and about half lift down on the intake closing!!

Now the difference is apron. 0,002 from half lift to full lift.

Anybody else had a cam with the same best lash at full lift?
The cam is installed with a degree wheel at 107.5 centerline.

Yes, I had the same results at FULL lift on each but some said maybe shaft deflection however I`m not convinced since I got .004 difference on every single one...........

Yes

Thanks guys, me and my two brothers will make an atempt to start this B1 engine tomorrow, and I needed some comforting posts, that this is all in order.

This will make setting lash easier, with all rockers at full lift.
I have two buttons for running the starter in the Jerry Haas Firebird. One above each valve cover.

Good luck and enjoy.............

Thanks, will post a short film, when the engine runs.

I have shaft rockers and have the same thing, at TDC the valve lash is about .004" more lash compared to setting them at EOIC method. So I always set them on the EIOC method and never had any issues.

Flimsy valvetrain and a small cam shaft core,it is what it is. Just put another hot dog on the barbecue ,crack a beer , and turn up the radio.

I don't know I have a billet cam, MRL solid lifters, Manton pushrods and T&D shaft rockers. I don't think that is the issue but I could be wrong...

Stock size parts plus huge springs and radical cam lobes equal problems.
It helps in my opinion to set the lash where you see the most clearance just to take some impact loads off the parts when the lifter first contacts the opening ramp.

my dad and just set the lash on a new motor today. We moved the exhaust valve to max lift and it did loosen the lash on the intake a small amount, I didn't mess with measuring it but it made the feeler gauge go in and out easier. We ran it EOIC because that is what the man who spec'd the cam recommended.

I use EOIC because it's so easy - even a caveman like me can do it.

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?

I bet that would work awesome on an engine stand.

You are assuming that somebody could get to the crank bolt to turn it 90°? Hahaha

Not in my rig.
We're hot-rodders.
We do what we need to do to make it work.

Ya, it can get pretty tight up front if you are running a blower, etc. I made an adaptor because my crank bolt isn't accessible. Still a pain. End up using a remote start switch and just get as close as I can bumping it over.

I pull the cover off my starter relay and gently bump it over that way. No way of getting to my crank bolt after adding the twin big fans and shroud to cool the thing on the street.

Not ASSUMING anything - I KNOW that you have to have a method to turn the crank no matter what method you use.

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.
