thats my manifold. I'm putting it on next week along with a zz4 cam. can't wait. I'll post pics and stuff when she's on.

EDIT: This thread in posts #11 and #13 has pictures of the manifold fully assembled and on that HT383, it also has some pictures of how it was made. here:

I actually purchased it from 350SS on the PPE forums and he was the one who got it all around. the fabrication of the GMPP intake to MPFI, and to accept the vortec TB was all done by Kevin Thompson at hot rod solutions (http://www.hotrodsolutions.net/)
it was done very well and clean. you could do pretty much the same thing for any manifold that works on vortec heads, however, the GMPP TBI manifold for vortec heads is the only one I've seen that retains the EGR, and my manifold was also modified to retain all EVAP stuff as well.
