07 Intl 9400i with CM 870

[Coronati]

I have a 07 International 9400i with a CM 870. Motor has just been rebuilt (out of frame), we had to change out the block. Old block had a horizontal 8 inch crack running thru the cooling jacket on #5 cylinder. This engine has been De-mandated ever since I got this truck last year in August. I need some help getting the ECM dialed in to run right with this modification. Who would be the right person to get in touch with for the proper information. Thanks.
