Is it a Gen 2 hemi? You need motor mounts, a hemi starter cable from battery to starter, bracket to accept throttle cable. I did this swap in 71 cuda, but used a hemi kframe. I went from a 440 to hemi. After I had k frame in, before the motor I thought it was down hill till I went to next step and had to order more parts. Flywheel is 8 bolt on hemi. You have to get Schumacher mounts for hemi, when I did mine he didn't make the mounts so I had to go with the hemi kframe. Exhaust may also be a problem, I went with the cast iron manifolds, because I had a bad experience with headers on the 440 that wrapped around the torsion bars. I had ex manifold jet coated and after 15 years still look great. Good luck with the conversion. You won't be sorry. Sure fills up the engine compartment.
