    I have a 350 prom that has a jet chip file on that I could probably part with. Will this work?

    Not sure if this will help you, but I did some research...

    Go here: http://www.efitune.com/broadcast_codes/ and plug in AZFT and ANTZ. Both are 1987 454 TBI .bins, (l19 engine RPO) TH400 and 465 respectively. Click the link under "get bin" for each.

    Download tunerpro RT http://www.supportfitness.com/mark/tunerpro/ and load the right ECM (1227747 for the 454 /bins listed above) then open those .bins.

    Now you can view the differences between the two, plus if you bought the burning stuff for around $150, you could burn those to a PROM and you'd be set with stock .bins, plus any mods you wanted.

    Maybe more "work" than you want to do, but there is something cool about being able to actually see what the PROM is setup like. Besides burning, everything I've listed is free. :)

    If I'm not mistaken, at some point the 454 ECM changed to something other than a 1227747, but I have no idea what. I suspect 1988 was a change, on that first link I didn't see any 1227747 with an L19 engine option. Again in 1991 it would have changed due to the 4L80E option.

    My 88 454 with TH400 stock chip is an AFTH with a 7747 computer.

    That website shows AFTH as a 1987 bin, but I'm not saying the data is 100% accurate either. :)

    Typing in "L19" and selecting engine as the search will bring up post '87 stuff, (a whole lot of looking to be had) but from what I see, none of the code links indicating what vehicle it actually was (C/K/R/V/P/G) work. :( I suspect it follows the same R/V for our style trucks, but again, I can't vouch for the site other than it's a tool.
