1991 Suburban 454 swap into 1989 Suburban 350
I have a few questions about swapping a 454 out of a 1991 Suburban and installing the 454 into a 1989 Suburban 1500 that has a 350 into now.
Will I have to run the 1991 454 PCM and will it connect to the 1989 wiring harness?
Do I have to change out the motor mounts on the front crossmember?
Is there Anything else I need to swap over to the 1989 1500?
