Autolite 4100
Any experts on Autolite 4100 carbs? Have a `56 f-100, mild 312cid
with 3 Pots on offenhauser manifold. I want to change to a autolite 4100. Want to know if a 1.08 venturi or a 1.12 venturi 4100 would
give me the best performence and mpg. The cfm of 1.08 seems a little
small [480] and the 1.12 [600] seems a little much. Anyone with any
experience or expertize. I leaning to the larger [1.12]. Is it better to
have more cfm than needed rather than less? As you can tell by my
question I dont know to much about carbs but know I want a Autolite
4100. Thanks

With your calculations looks like the 1.08 is perfect, But I think I`ll take
your advice And go with the 1.12. Was sort of leaning that way anyway.
Thanks, LxMan1--I appreciate.

LxMan1, Thanks again. As you can see I was looking for good info
but really wanted some back-up [read agreement] for what I really
wanted to do. Anyway glad to hear you feel the 1.12 v. should
run good as well as 1.08 v. Thanks for your expertise.
