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.
