My truck is a '74, but the engine/trans/TBI was from an '87. I used the '87 ECM. I got the long block + all of the accessories, TBI, etc in a box, so I kind of pieced it together with some other parts I had laying around. It came with a TBI spacer, a fuel pressure gauge mounted in the fuel inlet, etc. Since my truck is a '74, I was able to use a factory '87 tank, but an inline fuel pump should do just fine for a TBI setup. There isn't really any need to reinvent the wheel there, all you need is fuel in and a return to the tank. The FIC harness doesn't support any of the emissions, so I eliminated it as well. Here is a link to my build thread:

http://67-72chevytrucks.com/vboard/s...d.php?t=317519 . Lots of good info in the TBI swap thread, maybe not as much in my build thread. Hope that helps. There is a lot of good info in the 88-98 section too.
