I have a Ford Holly 94 carb I want to replace the power valve with a plug. I was told by Jim at Bubba's that Ken or Uncle Max would have one.
Please let me know. Thanks garyb1

I am sure both of these Gentleman would have power valve plugs. In my opinion, unless your carb is a secondary on a multiple carb configuration this is not a good idea, as it tends to provide a lean mixture at low vacuum levels (esp. at WOT). If your carb is a secondary, plug it and bump the jet size up one or two sizes to richen it at low vacuum levels.. If you already know all of this, you have my apologies and.......nevermind,...jack

As Jack says, not recommended for street. But I have three 94's on my dragster and I use spark valve for a plug. They work fine for a PV plug. All the kits have one in it and all the older carbs don't use them so a lot of us old Ford gearheads have a bushel of them. Walt
