C4AFDG Autolite 4100 question

[tdyltc66]

Thanks for the PM Dan, that is exactly the kind of information I was looking for. I do have access to air so I will conduct that bench test that you described. My car is only occasionally driven: to cruise nights and local car shows and such. It is never raced or horsed around, unless you count the occasional quick departure from a stop light (and who can help themselves in a situation like that). So unless someone is willing to trade me even up for a 289 hi po specific 4100 carburetor, I guess I can live with the slightly under performing C4AFDG. Don't get me wrong, I would love for the car to be correct in every way, so if you know of someone willing to trade, I would like to talk to them. Maybe I could go on A big Ford or Mercury forum and find some one who has the opposite problem. Thanks again for your interest and help. tdyltc66
