Getting ready to build a 440 engine. Been building Mopar's for a long time, and all the engines I have built before with adjustable rockers used a rocker arm with a ball adjuster and a pushrod with a cup. I am seeing a lot of rockers now for the 440's with a cup in the rocker like a chevy engine, and then they would use a chevy style pushrod. I also noticed the cup in the rocker arm style the push rod cup is pressure fed while the old ball and cup style has a squirter hole giving it splash lube. It also seems the Chevy style rocker would have a little better geometry as well as better lube. The ball style rocker makes the push rod swing through a bigger arc than a cup style. Anybody used the new style rockers on a Mopar? Stock Mopar hydraulic rockers have a cup in the rocker. Any thoughts?

All I know is people using ultra high lift cams use those so they don't have to think about the cup hitting the rocker. I think they use pushrod oiling in that application. Anything I put together has under .700" lift so that's not an issue for me. And of course it's too complicated for an old geezer like me. I like the stock oiling. KISS is my motto.

The chinesium $200 ebay roller rockers also use a ball-ball pushrod.

If the price is similar, i would go with ball end pushrods, cup adjuster rockers. Thwy allow more choice, allowing a more radical lift cam and stand up to very high spring loads if they are good parts. Ppl

Yes, sometimes engine builders switch over to ball-ball pushrods although it isn't an requirement. I've used both and there are advantages and disadvantages. My old 514 race engine used Jesel rocker arms with cups in the pushrods, but the cups had to be a special order size to fit the Jesel rocker arms.

Any thoughts? Your question is too general to give complete advice. If you have a bunch of valvetrain related questions and help deciding what you need then Mike at B3R is good and carries many products. Geometry is designed into a rocker regardless of the adjuster. Depending on the head, cam, RPM etc there's usually more than one choice that should work. Think of the valvetrain as a system.

Went to look at those and saw they have also "cloned" Comp's Pro Magnum bushed steel roller rockers for about $600

I just saw those too. They look interesting. If anyone has used them,, feedback would be appreciated. I use the comp pro magnums. I like the rocker, but the shafts are starting to wear..........

How expensive would it be to have rocker shafts DLC coated? Then the bushed rockers might live a lot longer?

Probably not too much, $50 ea. ?? I was thinking about doing this before putting my motor back together. This might be one of those issues that I want to fix, but not necessary.
