Holley Secondary Pump Cam
Hey everyone. I know the blue pump cam is common for the primaries, and I was curious, which color pump cam is recommended for the secondaries on SBC's?

Re: Holley Secondary Pump Cam
Really gonna depend on the carb size and what the motor wants. Does the carb have the 50cc rear pump or the small one? I have holleys on a couple of my camaro's and I have only changed the pump cam on one and I don't remember what color I went with. Its mothers day weekend, so I probably won't get a chance to look until next week as to what we are using.

Re: Holley Secondary Pump Cam
In all my days, I have NEVER seen a carb that was dialed in SO GOOD that the "next worst" thing wrong with it, that needed tuning, was THAT. ![Wink](https://www.thirdgen.org/forums/images/smilies/wink.gif)

Put whatever comes in it, in it; and run it.
