Not all 220s are built the same. The thunder racing version i believe is more in the .551/.551 lift range. The LS7 spring are good to .550 or .570 or .590 depending on who you talk to. Darnie1987 has a 5.3 with that same cam and stall on 33" tires and can't get traction to save his life so should be good for you as well.
