Thanks in advance guys (sorry if I sound like an idiot, I'm not exactly a gear head ................... yet)
A stroker motor is an engine that utilizes a different crank to achieve more displacement with the same engine block. A stroker's greater than stock displacement is due to an increase in the factory crank throw. An increase in crank throw increases stroke (the difference between the piston's top dead centerand bottom dead center position), which translates to more displacement. Longer rods are used to increase leverage and minimize the high degree of rod angularity created by the increase in stroke. The longer rod also prevents the piston from being pulled out the bottom of the cylinder bore.
