Hi Gary
Thanks for your comments and explanations, very clear. You are right, the Pontiac 8 had Carter W1. I am not sure yet what kind of carburation system I will use, I have 2 possibilities:
Option 1: Only one manifold intake and the 4 carb mount, solid linkage, not progressive. All works together. I will have to select the carb with cfm minor to cfm to W1, I think so.
Option 2: One carburator for two cylinder, like yours (I prefer this)
In option 2, I do not know very well (I am not carburator expert), which is the cfm correct to select the size of the carb. I think you will have a high idle. I suppose…
What do you think about it?
Thanks and Regards
Pacho
