A buddy of mine put a cam with very similar specs as the first one you listed in his daily driver Ranchero with a 351-W........idles like the stock cam and pulls really good from idle to about 5500 rpms, also gave great mileage on the highway.........
I was impressed with the performance considering he changed nothing else from a bone stock 1972 351-W..........
I think this would make a good combo for your intended use.........
