Special Notes: 1
Although never shown in production figures there were approximately 25 to 35
factory built 1966 Ram-Air GTO`s (XS package). It is estimated that 300 dealer
Ram-Air packages were sold for 66 GTO`s. A 421 cubic inch motor could be ordered and dealer installed in a 66 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.
