Most of these starters are the light duty kind meant for 6's & 283.s. I get the high torque starters from big olds. & pont.s etc.at the pull your own parts salvage Lots. You often find them laying on the ground or hanging by the wires. Then o-haul it & use your drive end housing. You can tell the the good ones, they have 2 lugs coming out of the starter that hook to the solenoid & a spacer between them & the solenoid. I've never used one of the little starters but I understand they are stout.
