392 in a 70 Duster

Did you have to modify the firewall to accommodate your 6.4? We’re you able to set the car down over the 6.4?

More pics if you have them. About to start my Hemi swap and the more pic’s the better!
Yes firewall needs to be massaged a bit this is what I did be sure to check wiper arms underdash as they can hit if you make the pocket to deep try to take off as much as you can just below the wiper motor bottom bolt this is where it's closest
