Holley/Mopar '6160' carb

[MopaR&D]

My cousin's 1972 Polara 440 came with a Holley 4-bbl. with "LIST-6160-1" stamped on the choke tower. Not much info about them online, only that they are an OEM Chrysler carb made by Holley. I have a new 360 Magnum in my '70 Duster with a 625 cfm Carter AFB that runs OK but not great (runs a little lean, needs tuning). Would I notice a difference in performance if I rebuilt this old Holley and swapped it on vs. tuning the Carter or is it not worth the trouble?

i would tune the carter instead of a 40 yr old oem carb...

how does a carb run lean in denver?....lol

I wondered the same thing, this carb ran pretty rich on my old worn out 318 so I wasn't sure what to expect. I think the jump to 370 cubes (360 .060-over) and 10.5:1 compression made a big enough difference in airflow...

Anyway I swapped the step-up springs today and that definitely made a difference, you can feel the point when you reach the vacuum where the metering rods change height. I think it runs a little lean on the 'cruise' step but once the 'power' step comes on it pulls REAL hard, you can even hear a little change in tone of the engine with my loud mufflers (SO COOL lol). That's OK with me since I want to cruise a lot anyway and would like to save gas however possible.

Still is the old Holley worth saving and rebuilding or should I sell it? Do those carbs go for any decent amount of money for restorers?
