13B 4port holley 600 jetting
I have a 13B 4 port that has a nice streeetport. I installed a RB 600 holley. I am running #60 primary jets and think it's running rich. I'm located in Las Vegas, NV. Should I go with smaller primaries or leave it alone? No stumble at all. I also smell alot of fuel while i'm driving.
Is the power valve still installed? I've had good luck with 58's with a powervalve, and 64/65's with the power valve blocked. That is on a double pumper though, (69 secondaries if you are wondering).
I think the secondary metering block conversion kit is well worth it, metering plates suck.

Thanks for the info... I have a single 600 cfm carb. The power valve is plugged. The spark plugs are a little black so i think it's a little rich. They say here in Vegas you have to go smaller jets because the altitude here.. will try 58 primary and see what happens. Is everyone running 6psi to the holley?
Are your floast set to the bottom of the sight plug hole? It seems odd to me that you are running rich on 58's with the PV blocked. When are you running rich, idle, cruise, accel, wot? Or all of the above?
