How are early Holleys ID'd ?. I have a few different carbs from my '63 and '61 and a few spares and I am trying to figure out what they are. Can anyone list the characteristics of different models.
I also picked up a glass bowl carb and am trying to ID it.
In the last pic I'm pointing at a casting # on the bottom reading GR2106B
Thanx, Powerband 8)
