Howdy,
I have 83 Buick Electra with a small block 307 olds that I would like to replace with a big block 400 or 455 olds. I'm told that the only major difference is the width between heads and deck height. Will this be a easy swap and can a Pontiac or Buick 400 or 455 be used as well?
Thanks, NeoVintage
