I don't have a Camaro yet, but it makes me feel better to add up the hp of all my stuff. Try it out, see what you get!
S10 - 180
CTS - 255
Mercury Outboard - 150
VW Beetle - 160
Briggs & Stratton lawn mower - 6.5
Air compressor - 2
Total = 753.5 hp
Now if I could just figure out how to combine them...
