I am not new to oldsmobile but I am new to the eighty-eight. I recently got my hands on a 1985 delta 88 and wanted to swap my 3.8 V6 with a V8, possibly a Hemi if funds allow. What I want to know is A: Has anyone heard of this being done before? B: Is this even a good idea? and C: would it be hard?

PS its rear wheel drive
