Roller cam fuel pump rod?????

[nasty72nova]

I have a retro fit hyd roller cam in a sbc. Howard's HRS 110245-12 is the part number. What is the correct fuel pump push rod to use in order to avoid wiping the lobe out?? I see they make roller tip fuel pump rods but what keeps it from just spinning in the bore? I wanna get this right the first time. I will spend the money to have it right. (Not that i have it) I invested $800 in the cam so I can't afford to ruin it.

Thanks!

I used a bronze tip unit from Comp cams on mine.

So far no problems.......

I highly suggest calling Howards and ask! I have used roller cams that called for bronze tips and some regular steel. As you know...getting it wrong will hurt more than the cam, your engine will get trashed.

Yea I called Howard's. The said bronze is fine.

Your question about the roller rod what keeps it in line is really quite simple. There is a slot in the rod that lines up with the 3/8" tapped hole in the front of the block. Then there is a long set screw with a pin on the end that fits in the rod slot and acts as a guide to keep the rod in line.
