This ECM was specifically developed for V6 application. ECM will run V8, but limp mode will not work and calibration is off for a typical V8. However, you can modify VE and SA tables together with larger injectors. As is good enough to start your motor, but as for driving - very iffy.

The 1227747 ECM's are so common you should be able to find a 5.7 OD auto version pretty easily and save yourself a bunch of time & effort.
