Yeah, an Olds V8 is not original or different🤣. I like a good V6 like my 305 hp Challenger, pushing close to 40 mpg with a 4100 pound car that runs 14's in the 1/4, the same as a 3.8's 0 to 60 mph. I got 24 mpg Imperial, only 2 mpg less than the 260 and it feels twice as fast. I can still find original 40+ year old Olds 350's in good running shape. The 3.8 were not near as reliable and dangerously under powered in stock form. A 3.8 or 260 will never add any value unless it is the later EFI Turbo T Type or GN.
