Is the 8 speed auto tranny the best choice for this project? If not which one would you choose, I have a clean slate so all options are on the table up How do I identify the motors and tranny to make sure I get what I'm trying to buy?
What are the years to look for and buy the 6.4 motors and 8 speed trannys ?
Is it best to try and use the stock wiring harnesses and controller or buy and use custom after market parts?
Thanks in advance for all the help your offering! bow


I know that the stock 6.4 uses only ONE narrow band o2 sensor, that makes it useless in my opinion, Holley has a good wide band set up for the gen 3 hemi
