    Well its been awhile since I,ve posted with progress so hear it goes.
    IF you are following this and want to do the same it was not easy.
    the first thing is a 4.3 vortec. the later years have a split intake that will be easy to modify

    God that is badass! Why the heavy mods to the charger? Had it laying around or no aftermarket option that was feasible cost wise or application wise? I'm diggin it

    That blower cost me 70$ so if I screwed it up to much I was only out that much.
    The fact that it was off of a fwd Gm 3800 means the injectors did not line up with the blower.
    The back half had to be modified so that the original throttle body did not go into the fire wall.
