i turned the trans. pans 350 and 400 (2 ea.) up against the floor board on a blown el camino 4 weeks in a row. sheared the bell-housing off at the pump. i was hooking to hard i guess (i changed everything on the truck) and with the blower, one of two things are gonna happen. you were gonna launch or break something. that when i built a blown drag only car and stopped dragging my st. car. has it happened more than once?
