I just bought a set of these pushrods: http://www.summitracing.com/parts/CCA-7442-16 And seems they were bent before they came out of the box. I was setting lash on my engine and when it was all done and i was spinning em by hand I can see them wobble some....so they are a bit bent. Or maybe the cups installed a bit crooked? Anyway they DO NOT spin on center, they wobble while spinning.... Is this wrong or is it normal to see a very slight wobble even on brand new pushrods??? Id say they are defective???

However, when I install em in my engine with last set...and I spin em with my fingers when the lifter is riding on the cam's base circle I can DEFINTELY see em wobble some when .... So? Has my OCD probably taken over???

In the late 70's my Friends and I flew down to Daytona Beach for a little vacation. My one Friend was reading a National Dragster magazine and said hey Crane Cams is nearby so he called and arranged to take a tour. We really enjoyed the tour and towards the end of it sat a little old lady hand spinning pushrods in a jig with a dial indicator and smacking them with a hammer to straighten them out. LOL at quality control at its finest. 1970 Duster Edelbrock headed 408 5.984@112.52 422 Indy headed small block 5.982@112.56 mph 9.42@138.27 Livin and lovin life one day at a time

The fix is to bend them back to straight again. I would say in the OP's case, the cups are not perpendicular to the rods. Could be sloppy machining. Mike Beachel I didn't write the rules of math nor create the laws of physics, I am just bound by them.

I found 6 to be "acceptable" and 10 to be "too wobbly". but then again when i roll those 10 bad ones on a piece of glass they look ok...i can see no visible wobble with my naked eye....

One thing to check is the pushrod tip the right size for the lifter cup? some have 5/16 cup some 3/8 and the same with pushrods most get the cup on top of the pushrod right and miss the lifter cup. Something you might want to look at.
