Need help with 3x2 carbs

Hi!

I just found three holley six pack carbs in the basement that my dad bought 20 years ago.

I want to identify them but i cant find any good info on them, what car they are for and when they were made.

Outer carbs have list nr 3659 stamped and date is 2003.
The center has list nr 4782 and date 0893!

Can someone help me ?
