Oh, my bad. I’ve been following your build and I guess I forgot that.
With the Holley mounts moving the motor forward about 1.75”, the AC compressor is a bolt on. It’s one of the reasons I went with the Holley mounts myself.
Note that it is only a bolt on with ‘11+ motors and since you have a 6.4 you are good. An ‘03-08 motor can’t do it, and the ‘09-10 motors need some parts swapped (I think).
i always put my builds on a forum as then holds me accountable to get them finished haha. Plus honestly if not for forums no way i would have atempted my last build and so many tips and tricks. Also a lot of money saved on parts etc.
