I would say 351W all day, the low end power is just so addicting. Take any 302 power figures and pump them up with the same exact parts -
As for intakes - I've run the adapter and it chokes power, buy the Typhoon 351W intakes off of Amazon/eBay/Corral and enjoy the power. Or buy the genuine Edlebrock stuff if you care - VERY noticeable power different with those intakes over the truck lower and car upper.
I've run the 351W with the Mustang injection and Explorer front dress and it works great. I've also run the 351W with FiTech and have had excellent results with that too - FiTech can handle the more radical cams profiles and allows you to view and tune any setting on the fly with the handheld, its super nice.
You know you are doing something right when the GM guys are asking questions about the motor in your Bronco - it's just a small block
