Just wondering if anyone knows for sure how much power there is to be gained from pulling the emissions equipment on a stock motor. Thanks

Well by disconnecting the air pump you free up a few horses I'm sure. Everything else is just to make it so there's less potential vacuum leaks and to un-clutter the bay.

 

You should not disconnect the air pump unless it is done with the removal of the catalitic converters. You will plug them up without a air pump to supply fresh air(designed to be used with a air pump to mostly burn the unburnt fuel the engine didn't burn to meet early '80's emissions) otherwise you will end up with melted cracked cats that don't work.
