I have a alfa romeo 147 with 145 hp factory and 25hp boost, the engine is diesel 1,9 multijet with 4 cylinders, also the car weighs probably half the camaro around 2000 pounds. Also I have diesel 63 mpg highway and 40 mpg city, that's 5 l /100km and 8 l/ 100km, hopefully the math is right.
aside from the rear drive I expect due to near identical power /weight ratio they'll feel close.
The V6 is very impressing especially compared to old engines.
nowadays there are new 2l engines with 260 hp, when you do the math a 6.2l gasoline with just 422 hp is the weaker, it should brand 650hp.
I'd say out of the V6 and V8 the V6 is by far the better engine.
