Preferred carburetor for mild 360?

Don't even need to drive it to sort out the idle. Crank in the initial to about 16 and the carb may clean up a bunch, increase vacuum and hold those currently fluttering metering rods down. You'll need to reset the idle speed and adjust your idle mix screws, pretty basic stuff.

Once you get that done, you'll need to figure out the total number. Do one piece at a time and it's not bad.
