I've got a pushrod story for ya:

Had a 440 in my car for a while, pulled it to build a Hemi. My brother got the 440, but I kept the fuel pump pushrod along with the front accessories. He rebuilt 440 with a Comp Cams pushrod, while I built my Hemi with the old factory pushrod. We both used the same Carter fuel pump, run the same VR1 oil, used the same Melling oil pump, both used a shelf Comp Cam, and broke in the cams the same way.

The Comp pushrod, after a couple thousand miles, eventually mushroomed to the point of not functioning. It is now stuck in the block, and he is running an electric pump.

The factory pushrod is still the same as when I put it in. It probably has about 85,000 miles on it between the 440 and the hemi.


You've been warned, run a factory pushrod.
