My brother and I are about to assemble my hemi and are running a Bullet solid roller. Do you folks have luck with fuel pump pushrods on a solid roller cam core lasting? We have a NASCAR pushrod with the brass end. Thanks for any input 👍

check your solid roller cam to see if it has a fuelpump eccentric. Many don't, leaving you no options for a mechanical pump.
In theory, there is no difference between theory and practice. In practice, there is.

I would call the cam company and ask to speak to someone that has worked with those items. If wear is an issue, it might be possible to make another pushrod out of bronze or brass shaft?
