I have not gotten this far yet, but depending on what info I find and how hard it is to convert, I am keeping this option open...
I am real close to embarking on a gm based tpi for my 360. I did a junkyard based 4.0 injection on my 258, and the results are pretty awesome ( I can just jump I'm and start the cj up and drive off in 20 deg weather) so that further makes me want to do the 360.
I would be interested in seeing your notes on the ecm you are looking into. I have the tpi intake already made (purchased from rawdave) and I picked up a complete(I mean complete- from engine all the way to underdash) 1990 vette wiring harness. I have read that these can be tuned via the diagnostic port that is under the dash. It may be easier to the route you are looking into though.
