How much weight gain from adding a Dana and roll cage.

Does anyone know if there's a weights thread of common parts that may be removed while building a drag car ?
I have a big pile of stuff I should weigh and post it.
Some of the stuff is so light it may be more work than worth the savings, but it does all add up.
