I have an engine data chart in one of my books that lists 3 different 409 engines for 1963. They are all 11.0:1 compression. The first is 340hp, and is the only one of the three that was mated to a powerglide trans. The second was 400hp, had a single 4 barrel carb, and only came with a manual trans. The third is 425hp, had dual 4 barrels, and only came with a manual trans as well. Hope that helps.
