2010 saleen camaro

S281 stands for the Saleen version of Ford's 281 cubic inch 4.6L V8 in the Mustang GT. The Saleen S281's performance specs are as follows (stage: "name of stage" -- horsepower/torque):
Ford Mustang GT -- 300/320
S281 Stage 1: "3-Valve" -- 330/340
S281 Stage 2: "Supercharged" -- 435/425
S281 Stage 3: "Extreme" -- 550/500
However, the Mustang only uses one V8 and we're counting on the Camaro having two from the factory. Therefore, I'm going to use the lower-end V8 for the Saleen version of our beloved 5th Generation Camaro, the Saleen S350, because it is the closest to the stock Mustang GT. Going just by guess work, I'm going to guess the lower-end V8 engine (let's just call this Z28 for now) to be 350 cubic inches with 350 HP and 350 lb/ft torque.
