I was taking my engines apart for some winter maintanence and I found half of my pushrods were cracked. These are the reccomended Crane pushrods with pressed ends that you would use with a 741 Crane cam. They have about 100 hrs. on them. Any ideas what would cause this. My spring pressures are 150 seat and about 470 lb/in. The springs do not coil bind.

go with one peice hardened moly .080 wall instead

Ratman, do you have a prefered brand?

Comp cams, Jesel are a few.Stay away from Manley one piece pushrods.They are junk!!!!I have seen sticks of butter that is harder than their pushrods.

Thanks for the info!

had the same problem. All one piece top dollar ones now. Comp cams I think.

Manton's, Smith Brothers are both good products.

Had Comp Cams one piece 3/8 in my race motor, 290# on the seats, .785 & .810 lift, over 600 runs plus dyno time, never a failure, available in .050 incriments for any application. Was a 540 Super Gas drag motor.

I stick with PRC's or Comps.
