I am learning about transmissions I will be rebuilding my first turbo 350 soon I have a question why did you put on a new bell housing was it damaged thanks
So you can replace it for a few reasons. If you break a hole or crack it and than if your racing and want an sfi bell housing so you don’t need to run a bulky shield. It will keep the flex plate or torque converter from flying through your floor.
Most people do the bell housing for clearance and piece of mind. But if your not racing I would see if you can get a used one. The sfi cert is only good for 2 yrs.
