But I suggest you sit down, do some math and look at how much you actually save running 87 over 91 or 93. I know for me, in a 98 liter tank the savings is $7 per tank. Running higher octane means more timing. More timing is more power, and more efficiency which is more mileage.
As far as a cam choice, considering what you want, I'd pick a stock LS6 cam. Or the venerable 212/218 which has been the standard mild truck cam for years.
