Should I trade my swinger for a big block?

I remember you had pics of your cuda out with your white dart to "play" not long ago.....that dart looks pretty sweet next to you cuda. If I was you I'd miss that car, you can always build an engine and that way to you'll know what ya got. If you traded your dart for it and the BB broke on you shortly after that would be quite the heart ache(not to mention *** kicker).
