I'm putting the 361 back into my 64 Fury, but am planning to change it over to an AFB 4 barrel carb. I have several that I have collected over the past 35 years of playing with Mopars, but do not know what they are off of or what the CFM size is. Can anyone help with the numbers? I have carbs with the following numbers: 3437 SB 4299 S 3644 S 3855 S I also have two that I think I know what they are from, but still unsure of size: 3856 S (65 Chrysler 383?) 3614 S (64 Chrysler 413?) Thanks for any help. Lee Sumpter
