For off the shelf cams the tfs 1 and e303 seem to work good with these setups and make good power . As for a stall if get 2800 . One day I'll have a stalled auto
TFS 1, E303, Steeda #19. Those are the most popular cam choice's for 5.0s. You could go custom but I don't see a reason too. All of them would be good for your setup
I went with a B Cam, my swap was the exact same except a manual. I really like the idle sound which is primarily why I chose it. http://www.youtube.com/watch?v=Fd-WtFeDFAE
