it's not going to fit.. Mercedes made the width of there cars very tight, and SB Fords and Chevys do fit, but the steering gear is usually in the way with the Chevys and takes custom headder on that side.. The Elephant motor is simply too wide.. Ford V8's are fairly common swaps. will also be much cheaper to build or buy compared to a Hemi. but you can make more than enough HP to have fun with
