Dan @ Eastcoast4wd offered me his Blazer with the 350 Vortec, 4l80 (from a 96) 203/205 doubler, for a pretty sweet price. I want to take my TBI 454 and put it in this, but I want to keep the 4l80. Since the tranny uses the Vortec ECM, can't use it on my motor. Only things that I can come up with is to get the ECM and harness off a truck that had this combo, (91-95) get a manual valve body, ( had that in my car and gets old) or swap in the 400 that I have that I was gonna use for my 62 burban. Anybody have any ideas?
