who would win?

But isn't having 800lbs less like having 800 xtra horsepower??

Um, NO. every 100lbs is only 1/10 of a second. 40% to 60% more horsepower and torque will outweigh that. Just like when my cousin raced his dad's northstar caddy against a 67 camaro with a 350. Okay, the camaro doesn't have a whole lot done to it but it's in great shape. The caddy still whooped it by 2 cars every time they raced. That's the torque coming into play. That caddy is heavier than the camaro. And the horsepower that you said it has is to the flywheel. When it gets to the wheels it's what, 97hp? That just doesn't stack up to a bigger, beefier engine with more hp/torque.
