the throttle cable & bracket are specific , as well as the return spring bracket , you have the vacuum carbs as per factory or the 3 mechanical carbs with the fuel lines on the drivers side ? If they are mechanical you will probably have to make fuel lines unless thay are on the carbs . Air Cleaner ? Center carb is 61-62 jetting , maybe 78-80 for the 500 cfm carbs ?
 Roseville or Mancini should have what you need

What kind of base are you lookin for?
I have a non shaker 440-6 base plate and lid I'm not using. Is there a difference in 440-6 and 340-6 base plates?  :dunno:

Well the 340 6 Pack had a very unique & rare air cleaner base as it was only used on the T/A & AAR , but the carb spacing is the same as the big blocks as the fuel lines & linkage are all the same except when using the mechaincal carbs .
 The kickdown linkage is different as well as the carbs sit higher

PM sent.

I'm glad to hear good reviews of the 6 pack mechanical carb set-up because that's what I got this past weekend. Doing a little research, sounds like the preferred set-up for a 4 speed which is what I have.  :2thumbs:
