Holley carb question
 

If running a single inlet Holley carb for super stock can the fuel bowls be converted to a dual inlet?

Re: Holley carb question
 

The carburetor must retain its original configuration.
If the original carburetor was a single inlet, it must remain a single inlet.

And if the carb came with a metering plate in the rear bowl you can't convert it to a metering block.

I am pretty sure that you dont have to run the exact carb number any longer in SS. As long as it is the correct type carb and measures properly it is legal. Best to check with your tech director and get a clarification

Re: Holley carb question
 

But there ARE metering plates that utilize normal holley jets ;)

Re: Holley carb question
 

I know that metering blocks use a jet and if the carb didn't come with one on rear bowl it will DQ the car, I witnessed the car that this happened to at US National's this year in SS.

I did say "plate", not block. It's common practice, if you have the right parts

Re: Holley carb question
 

Correct, I used a Quick Fuel plate, that has replaceable Holley jets, but fits inside the factory float bowl. So there is no metering BLOCK between the float bowl and main body. It is a direct replacement for the regular Holley 4160 metering plate, using the original screws.

If modifying the stock plates for Holley jets, 1/4-32 UNF, the jet needs to be shimmed out to give the fuel room to make the turn. Being an old toy airplane guy I use two glow plug washers per jet. I have forgotten what epoxy Gregg from Tri-City Competition recommended but it’s still in my plates after all the drums of fuel we have used.
