sbc to bbc conversion...

Does having the small hump floor pan matter? Did big blocks have the high hump, or was it just 4x4's and floor shift trucks? What else is necessary when going from factory sb to bb?

The hump does not matter. Drop the big block in and go. You will need all the front brackets for the alt, power steering pump, a/c, etc...specific to the BB.
