I just did some research and in 08 there aren't and Monte Carlo's, I did not know they were discontinued. But in 06 and 07 the SS's had the V8 that's in the Impala. LS4 I think. 05 and back there were the sc 3.8's. They had a roots type/twin screw blower on the top of the engine and not a centrifugal one. Which may be your best option for the V6, or turbo
