Rebuild the carb or replace it.
From 350 to 450 depends on carb size and how big of cam u use and put headers on it and a good high rise intake and a 750 Holley to get over 400 and 400 torque Get the thinnest gaskets for those heads u can use and have them ported and polished .
The choke could be in need of resetting, the floats could be off specs, your carb probably needs rebuilt or replaced.
Check the intake for a bad gasket. Too much air getting in.
Impossible to answer as there are too many variables. You wouldn't know unless you dyno'd it.
A complete engine with flywheel, headers, intake, and carb will weigh around 520 pounds.
