L31 5.7L Vortec - CSFI conversion to MPFI

[Montecarlodrag]

Hello.

I got one truck with this engine, they installed a procharger and brought it to me for a tune. As you know the spider injectors have not enough flow for forced induction so I want to swap to regular injectors with rails.
I have seen some threads where several people have used a marine intake with rails that is supposed to be almost plug and play with minor modifications. However the threads are very old and the pictures and links don't work anymore so it's not clear exactly which intake and rails to use.

Does somebody here have the part numbers the parts I need to do this conversion? I only need part numbers for the things I need (intake, rails, gaskets etc), I can do all the mods, wiring and tuning needed, I just want to be sure I have a complete list of everything needed to be able to provide an accurate quotation to the owner.
Hope somebody can help.

Thanks in advance.

FYI, it's not cheap. Decent used intakes were bringing big money, last I checked new ones were in the $1500-1600 range, and use a 4 bolt throttle body. I did mine a few months ago, but that was because I was given a new take off a friend of mine had for free. The thread over at ppe has about all the info you can find on the swap.

The external injectors are the key so you don't have to rely on the "spider". I'll help what I can :)
