    I am looking at putting a Merc Cruiser EFI set up into my K5 4x4. I believe I have a complete system, but would like to know for sure. I am having a hard time finding a forum to ask my question too. I will post up a pic of what I have. Thank you, and if I am in the wrong spot please point me in the right direction.

    I found out today it is a MCM 320. I am looking for a diagram and some pictures. An application would be nice as well.

    Looks like you have most everything, but I don't think the system will work very well. Marine EFIs are "closed loop" systems, having no O2 sensor, and are tuned to a particular engine. Putting it on a different engine, or swapping cams, etc... will necessitate ECM reprogramming. And depending on the year of your K5 and your location, the swap may be illegal. I'd find a rusty old Suburban or Blazer with TBI and get the engine, ECM, and harness out of that. I did this recently to my '80 Silverado with great results, and it was easy because the 'Burban stuff all bolted right in to my Silverado.

    Well I think I just might go with a vehicle EFI instead, seems like less of a hassle.

    What do you think of this deal? Is it worth it?

    And what do you think that MCM 320 system is worth?
