Hey guys, been browsing the site for about 8 months now and finally got around to registering. Im hoping someone(s) here can help point me in the right direction.

My 05 Cadillac cts LY7 (3.6) motor blew a ring. I decided to do a motor swap. The motor i got was out of a 2007 Cadillac SRX with only 10 miles on it.

My question is for anyone who has tweeked with this motor or timing or is familiar with this motor. my 2005 has the old timing chain setup on it, while the 07 has a different timing chain setup.

can someone point me in the right direction as to what, where, or who i need to talk to to potentially get someone to reprogram my ECU to run the new timing chain setup. i can provide any other info needed for anyone who wants to weigh in

i really appreciate any help from you all!
