Fuel Pump Pushrod with a Roller Cam

Hey
I have an 87 motor that does have a boss for the fuel pump and it even has a hole in it. This was a TPI motor and I am going back to carb. It also has a roller cam! Can I just use a regular fuel pump pushrod or does it have to have a brass tip or something? I am assuming I need a brass distributor gear so I thought this might be the same thing?
Thanks!

Yes it has the lobe.

No you don't need a special fuel pump rod. A 87 LG4 car for example has a mech fuel pump with an ordinary rod.

You don't need a brass gear on the dist. Look at the one that's in there, you'll see it's not brass.

Cool! Thats just one less expensive part I need to buy!
On the distributor though I think I may? The one in there wasn't but I think the guy that built the motor was not the brightest so he may not have known. I thought roller cams were softer and therefore had to have a brass gear?

No.

Racing rollers (and billet flat-tappet cams for that matter for real racing) are very hard, and therefore require a softer dist gear. The design of the system is such that it will not work if there are 2 very hard metals; one must be soft. Factory rollers, and virtually all aftermarket hydraulic street rollers, are soft cast iron just like typical stock cams.

What about the factory "melonized" distributor gear? What is melonizing anyway?
