The AC vent is above the radio, it is splayed to blow air in a 180 degree to provide cool air to both sides of the cab. I haven't been able to look close enough to see if there are any more vents. I Have been able to check out some up grade intake manifolds in Summit but am not sold on the carbs yet. I may end up using a carb, but want to explore FI first. I also have a 1960 4x4 sw, which I was assured was a NAPCO and told all documentation from purchase is avalible, however is not in my hands yet,that I am working on. On the 60 I am going to do a total and real restoration, very anal all factory frame off make your Momma prowd resto. When I get the docs in hand I think I will see probably not a NAPCO, and a 235, so I am now wondering if I should find a 235 of the right year to put back in it or a 292 of later vintage , or just go with a SB.
