Does anyone have the recommended metering jet and rod sizes for the 401 dual quad setup?  I rebuilt my carbs and it's running better, but I suspect it would run much better with the proper jets and rods.  I'm sure what I have is not the factory or preferred setup.

Thanks for your advice, as usual!

Thanks Al.  This is great!  Now to find the parts and maybe a new carb or two to be correct.  My carbs were apparently scavenged and are not the factory numbers.
