putting a 383 in a 72 cuda

I have a 72 cuda that had a 360. i currently have a 383 with a 727 tranny. my measurements tell me that it will fit in. the motor itself looks to be about 3 inches wider than the 360 and it appears that the mounts on the 383 look a lil farther back maybe an inch and a half. wondering if i can drop the motor in without changing the k frame. maybe change the mounts? any input would be helpful.
