Iam not really into monte carlos so here is my thoughts. When u ordered the ls5 it automatically got the ss454 pkg with all the mldgs badges etc,this car is a wolf in sheeps clothing no badges etc ,they beefed up the orig ls3 eng with forgred 11:1 pistons,square ports and intake with a nice cam and 800 cfm holley m20 trans coupled to a 12 bolt with 410 gears and it looks like a plain ol monte carlo.
