Guys,
I am about to pull my hair out over this issue! Would someone please tell me if it is truly necessary to use a bronze tipped fuel pump rod if converting from a stock flat tappet cam, to an aftermarket roller? I have asked many sources, and I get both yes and no. I'm wondering why there appears to be no authoritative answer to this question? Here is what I'm working with. Standard (post '87) 350 shortblock with a Vortec full roller conversion. My bumpstick is GMPP #14097395. The manufacturers literature says NOTHING about using a bronze tip fuel pump rod to protect the cam lobe, however, I've read/heard about this being necessary to keep the lobe from being "chewed up" by the OEM steel pump rod. I have the original steel one, and a brand new Comp Cams 4607 as well. Which should I use? Oh, and lest I forget to ask, do I need to change the distributor gear too? It is the stock unit that came in the original (flat tappet) engine.
