depends on if its a 2 or 3 circuit carb.
it can be converted to a 2 circuit easily anyway.
I have a friend who ran a 2 circuit with success on a 355 w/auto trans.
poor idle below 1000rpm but he didnt play with the air bleeds.
boosters are easy enough to change on the 4500/750 to go to 1050 :twisted:
I have used the old 1000 cfm 3 barrel on a 350 I ran and it really made good power, and idles better since the primarys are smaller. not much better than the 4150/850 on that size engine IMO.
