Best carburetor and intake manifold for a 273?

Performer, it has the 273/318 port size and is probably the cheapest AL intake out there as there are thousands. 66 will bolt up fine. carb can be an Edel/Carter 500-600 or even a Holley 1850 600. Either 500 will be double the price of a 600 as they are less common. 273's are usually pretty soft on the bottom end so some taller gears work best and can carry over to your next motor. Youll need the 4bbl kickdown stuff unless you can adapt your 2bbl top rod to reach the new farther away carb linkage.
