Tim: All right, son. This is an ordinary lawn tractor and we have to Tim-Taylorize it. So first we gotta remove this puny 12 1/2-horse Blade-O-Matic motor, 'cause we wanna cut lawn maintenance time way down. So what do we need?
Mark: More power.
Tim: You learn well, my little one. We're gonna replace it with this. Because this is more power.
Mark: Wow.
Tim: Darn right, "wow." This is a twin-cylinder 1600cc motorcycle engine, normally aspirated at 58 horsepower. Your dad has ported and polished it, blueprinted the crank, and balanced it all the way through. Huh? It's got a reverse gear - who needs it? four forward gears and a suicide clutch. On a good, clear day, the ET on this bad boy should be under 15 seconds at quarter of a mile. We can do zero to 60 in under 5.5 seconds.
Mark: You gonna race it?
Tim: You bet. As soon as we install this bad boy, we're gonna enter the Indianapolis 500. By the time the rest of the pack catches us, we'll have won the race and mowed the infield.
