Official 3rd Gen Hemi thread
Here's a picture of the Hemi in the car with the new firewall. I had to offset the master cylinder 3 inches to clear the engine. I also will have to modify the TTI header so my steering is a straight shot to the rack as opposed to 3 joints to clear the header. I chose to use a Hydratech brake booster and I had to relocate the proportioning valve to clear the headers. The 6.4 engine is a bit bigger than the 5.7 so moving the firewall had to happen. Attached is a picture of the engine with the firewall in place
