Yes, you need to swap transmissions, add a front axle (somehow) and a lot more. The 845RE only can take a maximum of 331 pounds of torque, and you would definitely have to swap in a 8HP90. It would be far cheaper to just buy a AWD SRT8 300.
I was looking at doing the same about a year ago but looking up what it takes to do it gave me a better idea. I gave it to my wife and went out and bought one. Changing the motor was too expensive, and I found the motor itself pretty reasonable it was the job and other parts that made it uneconomical to go that route. Good luck ?
So I just picked up my buddies 300c and I'm looking at doing almost a demon 300 (in appearance anyway lol) so Ill post up a pic and let you guys follow along. Right now I have 3 things I need more experienced help with
1. The daytime running lights and halos I can only find 1 kit that will do...
