I don't like it. Would switching to Iron rockers help quite it down any? I know I would lose a little lift...Im using 1.6 rockers now.
Quote:How are you adjsuting them, hot or cold? Are the heads aluminum ot iron? If aluminum make sure and set the preload hot
It just sounds like it has solid lifters in it. I have tried 1/2-3/4-1 full turn and it still clicks like its out of adjustment. I understand the aluminum roller rockers may make it noisy.
I run a Comp Cams XE295HL cam and lifters in one of my 440 with Eddy RPM heads and Harland Sharp 1.5 rockers, nothing noisy in the valve train on it

no , you have to change the cam out to something stock and wimpy ...
Quote:I would try setting them warm, as a last resort
452 Iron heads. I adjust them cold 7/16-20 thread on the adjuster = .050 per turn. I loosen them and slowly tighten them until I feel drag on the push rod then turn them to what I am setting them at. Should I go more than one turn?
I like and use the method of setting the valves by turning the motor over on the starter with one valve cover off until the exhaust valves starts to open and then set the preload on the intake rocker arm, I then bump the starter over until the intake valve opens all the way and starts to close a tiny little bit and then set the exhaust preload, same thing on the valve lash 
I usally do one side and then button that side up and run the motor some more to warm it back up and then do the other side I don't like or use the Mopar, Chevy charts

Quote:On the 7/16 x 20 adjuster I would start with 1/2 turn warm or hot
Cab, I will try that.... How much preload?
Let us know what you get

End of story. Nothing you can do about it.

With all the clatter and messing around trying to adjust them, I don't see what the point of the big hydraulic cams is, might as well have a solid and make more power all other things being equal.
One thing I wish I would've done different with my 440.

I have a big hyd cam from straightline performance and I just replaced my lifters with a set from Comp cams. I was shocked that they just wanted the lash set from 0 to 1/8 of a turn as normally I would go to a 1/2 turn. Anyway I was surprised that they were as quiet as they were. Maybe it's because I am running M/T cast aluminum valve covers. (Very thick compared to some valve covers which may stifle the noise)

Agreed. Not to mention the quality issues with hydraulic lifters available today. So, faster ramps than ever, the need for much more spring pressure for control, and poor quality lifters that are generally more complicated. I doubt many are getting the performance out of their fast ramp cam profiles that they should. If you really care about performance, put a solid in it. Otherwise, put a lolli-pop cam in it, close the hood and forget about it.
I must really be the odd one out here. To me there is nothing sweeter than the sound of solids, and nothing say performance better.

I don't understand why someone would go to the expense of installing an adjustable valvetrain on a hyd. cam ???

Come on.. a SMART guy like you asks this?
The guys at Comp suggest an adjustable valvetrain to achieve preload. With my limited cam knowledge, I can see how that having each rocker adjusted to a specific setting compared to being along for the ride on a common shaft....Makes sense to me.

Nothing you can do that series of cams clatter--I think closing ramps are the culprit.

Me too. A little sewing machine sound is nice... the sound of power.
Sounds like some guys spend more time adjusting valves on their big hydraulic flat tappets than I spent with my solid roller.If you're gonna run a big cam like that..might as well do a solid. I run the valves on mine in the spring(about 20 min tops) put the covers on and drive it all summer. The tight lash solids aren't even that loud...

Same here I adjusted them once on the test stand and once after about 5 passes three years ago.My valve train is pretty bulletproof though with bushed Isky iron rockers.
