Fuel pump pushrod?

[kenhaw]

Hi Guys and Girls

Need some info on fuel pump pushrods.
I have a 350 ZZ4 with the "Hot Cam" kit installed.
Do I use a bronze tipped or a standard and what length??

Thanks in advance

Stock length steel will work fine, you can use a stock Chevy rod or aftermarket, I recomend the ARP light weight rod

Well I am a little confused now. I have a similar post on another post and somebody there is saying to use the bronze tipped one.
Does anyone else have any input on this, also regarding distributor gear, but maybe this follows the pushrod tip so if I have to use a bronze tipped pushrod then I guess it will also mean a bronze gear?

Is it a GM Cam? You go by what the cam manufacturer says.

A bronze distributor gear or pushrod tip is usually required only when running a billet cam

I didn´t buy or install the cam. It was in the car when I bought it. All I know is that it is the " Hot Cam" for the ZZ4 or 385 Fastburn (350).
It is just that I have read a lot of posts claiming you will run down the cam lobe with the wrong pushrod and since I am experiencing fuel pressure fluctuations before and after my complete fuel system upgrade, I am affraid that this is the problem. I have bought a new Carter pump which should deliver 7-8.5 psi and I am seing max 6 psi.
I have a pressure gauge installed on the carb line at the pressure regulator and on the second carb line a sensor for a gauge inside the car. All hoses are new 8 AN and from pressure reg 6 AN, new tank unit with 1/2" pipe and 2 big filters 40 and 100 micron. I am going to check direction on filters tomorrow, would be nice if I mounted one of them the wrong way.
If a cam change is needed, is that a big job?

Oh and yes it is a GM cam.
