Just Thinking what do you all think

Had a friend years ago put a 277 i think hemi in a 69 dart. He never really made it street legal because it was near imposible to get the exhaust hooked up to the stock manifolds. It fit just fine tho and he did drive it some on the back roads around his farm. I say put it in there and just drive it. Not every car has to be fast. Should run and drive just fine.
