Proflow's Powertorque Mini starters provide extra-powerful motors that crank out up to 200 ft/lbs of torque. Coupled with their 4.4:1 gear-reduction ratio, that equals reliable cranking power for engines, up to a whopping 18.0:1 compression ratio. These starters come with a billet adapter/mounting block for durability. They'll also clear your modified oil pan.
