I have discovered a project of a lifetime. I ran up on a guy who has a roadrunner that he wants to sell for $2000. It has a hemi in it and it's running but it needs rebuilding. I don't care nothing about that car I just want to overhaul the hemi and put it in my 4 door cutlass supreme. I was wondering what would I have to change to put the engine in my cutlass. Any help with this would be appreciated.
