I have had great luck running the original setup so if it were me, I'd buy a set of the original Holley BJ/BK reproduction low-riser carbs tuned for your intake from Carl's Ford Parts. The original linkage is available from Greg Donohue Restorations. They are very straight-forward to setup and tune and are very street able. Also, lots of good info on this subject over on the FE forum.

I believe it's the BC/BD carbs that I recall reading recommendations on before, although I forgot they were for the MR motor. Sounds like the BJ/BK carbs are what I should have been thinking. My current carbs appear to basically be 4160 non-emissions, street/competition carbs according to my Holley book.
What are the BJ/BK carbs and how do they mostly vary from the later 4160/1850 carbs I have?
Thanks
Except for a last measure of original appearance, is there any reason I shouldn't expect the 4160/1850 carbs to perform well on the street? I have the Blue Thunder reproduction throttle linkage on the motor.
