I have a 3500 upper and lower intake manifold both ported and polished. PCM Tray. Heater tube and 180 t stat that will fit a 6th gen 3400 motor. More parts then that it was a package deal from milzy motor sports. Cost 800$+ for the package itself. Good gains and gets car ready for stage 2 cam and head swap. It is new never used. I ordered it and crashed my impala next day. I crashed before it was even delivered to my house.

 

Also comes with all adapters needed for fitment.
