would you know what sorts of mods?
my understanding 6870 has one injector driver whereas the 7427 has 2 but resistance of injectors would proabably be different

There's a couple resisters in PCM that need a solid jumper for 8 injectors. The Memcal mod with a wire when you read docs is not needed. Take a look in this thread for links to wiring and a Zip file with all that needs to be done to convert 97427 TBI to MPFI:

That's what I said but I guess it did not come out well?
