It sounds as if you are just looking to use your 4.5" bore block in place of a stocker 4.250" bore block, not wanting any headaches associated with the build or needing any tuning afterwards, just a smooth running cruise night car type of engine that is street driven and not beat on. Is that right? Not a performance minded stroker in other words? Can you tell us your expectations for the car/engine?
This is what I think he is looking to do.. just a
cruiser that runs on the low octane... will never
see the track and wants a low rpm engine... its
not my cup of tea but it may be his... when I had
my hemi it was years ago and it took a lot of tuning
to keep it right... now days if I were you I would
put injection on it
