I have several friends that work at comp and that is the same they tell me the same things...to keep the lsa up and the split wide...but dont go to much being on a forced induction engine.

 

Pretty mild exhaust note at idle as far as lope goes but that was also in my 6.0 and you got the 4.8 so it would have a bit more lumpy sound to it I'm sure but I dont think that it would be too radical sounding if the idle tuning is done right.

 

I figure you would instead of 551/551 you would need more exhaust lift like 556 or so...

 

5 thousanths isnt much bud....the gt2-3 cam has some very nice specs for a boosted 4.8! I like the sounds of that cam in there.
