I believe Mercruiser Marine offered some intakes with a Rochester 2-barrel for the 250. If you can find a small-bore Rochester 2G calibrated for a 265 V-8 it should be close to the right setup for a slightly over-cammed, increased-compression 250. Most people install WAAAYY too much carburetor when they do a street engine buildup and end up with a very peaky engine without much midrange torque.
