Can you guys help me identify what all of this is on the nnbs intake manifold? Thank you!

 

First pic top nipple is evap hose nipple. the side closed hole with bolt boss isnt used but would be used for egr.
Second pic small hole is for brake booster hose. the other part is just back part of manifold.
Third pic is bolt bosses for the intake cover bracket
Last pic is map sensor hole

 

Sweet thank you so much!! So I won't be using the evap hose nipple and I won't be using the brake booster either so is there a way I can plug it?

 

Brake booster yes. GM makes a fitting. We carry them. The nipple just rubber cap unless you cut it off flush tap and put pipe plug in it.

 

Ok do you guys also carry a bracket for the use of a dbc throttle body?

 

Yes we do. many. we have an adj bracket that holley makes. $32 + shipping.
