Having owned both (and seen plenty of examples of each), I would
strongly disagree with this statement.  Especially if you are
comparing stock 2nd gen vs stock 3rd gen or bolt-on 2nd gen vs bolt on
3rd gen.

All of the following are superior in the 3rd gen
intake manifold
head
cams
turbo
efi (better ecu and 550s vs 440s)

They are also newer, which typically means lower mileage and less time
sitting around not running.

If you are completely building the engine (ie cams, head work, intake
manifold, standalone, etc...), then yes the difference is negligible,
but most people don't go that far.
