any V8 computer will work. sorta.

I should say, if you currently have a 5.9L auto combo, any 5.2/5.9 computer out of a truck with an automatic will work. but look for a non-security PCM. otherwise it'll fire, run for 3 seconds, then the PCM kills the injectors because it doesn't "see" the correct body computer and thinks it's being stolen or something.

otherwise match the number of cylinders and type of transmission, and you're good to go.

but, if you are re-programing the computer like with SCT (sorry DaytonaTurbo!!) then you can use any 3.9/5.2/5.9 computer and simply load the program on it for your set-up.

Or if you know someone at a dealer, they can hook you up with a factory re-flash of the computer, which will overwrite EVERYTHING. they can turn a security PCM into a non-security PCM, a 3.9V6 stick shift to a 5.9V8 auto.
