Special Notes:
Although never shown in production figures, there were over the counter, and possibly dealer installed ram air packages sold for the 1965 GTO.
A 421 cubic inch motor could be ordered and dealer installed in a 65 GTO, but there were no factory built 421 GTO`s. A fully documented 421 GTO is very desirable and extremely rare. If not documented this application is incorrect.
