Hey im swapping the sb for a BIG block in my 73 K30, I need to know if ineed to change the bell housing, and clutch? I was hoping to only have to change the bell housing and buy a fly wheel:confused:

You'll only need a flywheel. The bellhousing and clutch parts are the same from sbc to bbc. There is a difference in clutch diameter so it would be a good time to ensure you have the bigger disc but even those interchange.
