You'll be much happier with a stock radiator, if you use a 2010 Camaro water pump. The waterneck is on the driver's side. It requires a minor relocation of the idler pulley. Dirty Dingo has a $26 kit to do that.
I used the 2010 Camaro pump, '05-'08 top hose, LQ4 lower hose, and H1 8.1L belt. My radiator is the OE 454 HD cooling option, with matching cushions and top plate from LMC. It's strapped down by a fan shroud I designed. Twin fans are from a LT1/LT4 Camaro.
Radiator was $140; Fans were pick-n-pull $20!!!; Top mount was about $40 with 4 cushions; Waterpump was $160, loaded with tensioner, pulley, thermostat and housing; Idler relocation bracket was $26; Top hose was $8; lower hose was $12; Belt was $35.
