No. My XER273 worked good in a 5.3 and great in a 6.0. It is a 224/230 and less lift and that is a pretty big cam for a 5.3 with twins. On a 6.0 bored out it might work pretty darn well. IMO

The motor is actually 3.905 bore 4.8. I thought i would try the cam and see what it does. Im running a E85 blow thru carb also so i thought the 112lsa might be ok. Probably be a turd down low but kick some *** on the top end. I guess ill find out.
