It's not really as stand alone computer, the TCM has to talk with the ECM. So you can't remove the Allison and use the stock TCM, but you can get stand alone controllers for the Allison. What's effed in on the motor?

I haven't looked at the truck in person yet, they say it is dusted,cranks but won't start. It might be repairable, just want to know what my options are, I was thinking about a 12valve inline pump cummins.

Well if you go with the Cummins you'll probably need a stand alone controller. A easier solution would be to find another LB7 motor.

agreed, the LB7 can be pretty stout, save the cash you spend on a 12v conversion, find a running LB7 from a wreck, and build it up a little, or better yet find out whats wrong with that lb7, fix it, and maybe build it up, put some cash in the trans and you will have a DIRTY fun truck!

Where are you at again? down south somewhere right?
NVM, Cremona, I have an aunt that lives in Carstairs, wheres the truck you're looking at and what was done to it?
