230 Block Question

And here's an interesting document...they put 400s into some '71 Newports.

Would be fun to find one of these, watch the puzzled looks from vin readers.

NOT rare I know, but I did have a '71 383 2bbl. cast crank SportFury. Makes sense that they would just go ahead and expend the last 383 blocks and offer 400s late in the model year in a big barge like a Newport. Awesome info, thanks!
