Carburetor cfm for a mild 318 build

I'm thinking about using a comp xe262h cam. Would like a little rumble at the pipes. Compression ratio around 9.25:1. Speedmaster cylinder heads ( bare). 1.88" intake / 1.600" exhaust valve's. Edelbrock performer intake, edelbrock 600 cfm carburetor. Gear ratio I don't know what would work with my planned combination. I haven't bought anything yet. Is this a good choice of parts for what I'm wanting to do with the car? I'm not looking for a lot of power but still I want it to be able to get out of its own way. Wouldn't throttle response and low to midrange torque be best for a cruiser?
I’ll answer all three of those questions with;
YES YES YES!
Good combo. That XE262H cam is 218 @050?
You can use the stock torque converter. More stall would be good but you can get away with a stock unit. (I did)
The lowest numerical gear ratio to use is a 3.21/3.23 with stock diameter tires. If you went with a larger diameter, I would suggest a higher stall in the converter.
