Whats up guys
i acquired a 64 newport and i have done a lot of reading with no answer. i have the 361 with strumberg 2 barrel intake and i would like to upgrade to a 4 barrel and my FIL has factory 4 barrel intakes just what carbs fit factory intakes?

next what is the difference in intake flanges. i keep seeing square bore but what other ones is there and what ones are compatible?

i know i am going to go with about a 600 cfm carb to wake her up, but what carbs and intaked?
