Awesome! Looking forward to watching your build.

For wiring and setting up your megasquirt, go to my DIY how to thread here:

Covers wiring, tuner studio set-up for the Hemi, etc. It will get you running.

Everything should line up fine with the swap flexplate. I believe the bushing in the crank stays??? Someone else can chime in on this hopefully.
