    The one I linked above is the proper one to use for TBI injection with Vortec heads. It's a GM part. I found mine on eBay for a lot cheaper than new, so check around, you might find one.

    Otherwise, there are a ton of carbureted ones but not a lot with the rear coolant outlet. You'll have to look around.

    Update - part numbers 12486572 or 12496821. They are the same part, just different numbers for some reason.

    Mine is a little different set up. I dont have the factory TBI any more. I have a sniper and no EGR. Edlebrock has one made for a vortec with out an EGR.

    I just read my current intake specs. Its made for a vortec and supposedly has all of the provisions including water inlets in all 4 corners. I know it has two up front bc i have one plugged with a dash temp sensor and one for my sniper. When i get my truck back im going to look in the back to see if the holes are plugged and i just didn't notice

    Mystery is solved. The truck came with a counter clock rotation water pump and I put a clock wise rotation pump. I have a professional products intake now which im not to thrilled about. The intake is made for a vortec

    Depeding on which model, it looks like there are two ports up front, one on either side of the tstat, that could be used for circulation with a fitting. There may also be two on the back but I can't tell from the pics I see.
