any cam will be able to run mech fuel pump. take a look at the lobe for the pump, it's barely a lobe; compare to valve lobes. you can push the pump lever with your bare hands; try that with valve springs. the load on the pump cam is just really low comparitively.
inspect the end of the pump rod for any flaws; lube b4 installation.
call your cam mfgr for confirmation/clarification of these things for peace of mind . . . good luck

thanks driveshaft, i agree, that's the really the kind of info coolcoupe needs from the cam mfgr he has chosen. i started to add qualifiers, but the list get long and with the if/then's and i type too slow.
coolcoupe, not all roller cams are made made the same, best to place a call to the mfgr . . . thanks

Some should be careful what advice they pass on, full roller valve train with billet cam is very expensive. I actually use a roller fuel pump push rod on my billet solid roller cam

do what you want Fb but my crane roller told me to use the bronze fuel pump shaft so i did it. they dont say to use one for the hell of it, its for a reason. it also called for a particular type of distributor gear but my msd had it already.

Steel billet like used on most serious solid roller cams needs a bronze tipped pushrod. The tip goes on the cam. A stock pushrod will destroy the steel billet cam.
If you have one of the cast core cams (like Comp uses)..or Austempered iron ones you can use a stock one...but the tipped one will work too.
Best dist gear choice is to have cam made with an iron dist gear so you can run stock gears.

When you order a billet cam you tell them you want a pressed on iron gear and this will work with any stock or aftermarket distributor.
My small base circle billet solid roller cam has a pressed on iron gear. You can order it with any profile you want and CCams will make it for you in about a week and they only charge about 40 bucks extra over their off the shelf cams which have that concrete look to them

Billet camshafts have been around alot longer than bronze tip pushrods.
I have seen many bronze distributor gears fail, but never a melonized GM gear.
Next you guys will want bronze tipped lifters on a billet flat tappet cam.
