Mine had almost worn down to the steel. Going to install an electric fuel pump for my carbed billet roller cammed engine in truck.
Bronze tipped pushrod. Check regularly.

When the bronze is gone bad things will happen. The roller tipped pushrod may be better? It uses the bolt hole in engine as a slot to keep it aligned.
I first installed a bronze tip in my 454 when I got it,but then heard about mushrooming if left unchecked.I went with the howards composite after that,now Im on an electric pump too.
No roller rod for the BB guys sadly.Still waiting for NASA to invent one.

All those genuine GM SBC crate motors ... some have a GM Cast Iron Flat Tappet camshaft ... others have a GM Billet Steel Roller camshaft. Research has revealed there are Two separate GM part numbers for their GM FP rods ... one for the cast iron cams ... and another for the steel cams. 
mea culpa, my mistake, only ONE GM FP rod pn for GM cast iron cams and GM billet steel cams
3704817 is THE sole pn
near back of stafford's manual is parts list for x602, x603 and x604 crates ... x602 have cast iron flat tappet cam while both x603 and x604 have billet steel roller cams. BTW, x603 is obsolete & no longer in production as is street ZZ4 version ... neither x603 or ZZ4 (or their alum heads) are available.
Also, I checked an older 2006 GMPP catalog (which has the parts lists in back).
Again, only ONE FP rod pn 3704817 for all sbc; regardless if GM cast iron or GM billet steel (sae 5150).

Hopefully you were just not running a high zinc oil. Unless you put an additional additive or run diesel oil or special oil (Joe Gibbs) you will suffer metal on metal part failures.
Jeeze, I didn't know that a stock fuel pump pushrod didn't work. You mean to tell me that GAZILLIONS of stock fuel pump pushrods are not good! Good grief Charley Brown, that's all I've ever used is a stock out of the box GM fuel pump pushrod.
As for assembly lube, sorry, I'm stuck on Isky (assembly) Rev-Lube on the cam lobes, lifters, push rods, rocker arms, and fuel pump pushrod. It contains melodeum disulfide. I started using it in 1974 when I installed a Isky Z75 cam kit in my 302 SBC. Every engine I built has had it and I have NEVER lost a part due to wear.

I use Permatex assembly lube on the crank and rod bearing areas and on behind the cam timing chain gear.

Sandlapper, do you happen to know the pn for the steel cam FP pushrod?All those genuine GM SBC crate motors ... some have a GM Cast Iron Flat Tappet camshaft ... others have a GM Billet Steel Roller camshaft. Research has revealed there are Two separate GM part numbers for their GM FP rods ... one for the cast iron cams ... and another for the steel cams.
