1965 Barracuda 'The Politician' ~ Ralph Costa
Alan,
In late-1964,
Chrysler {Plymouth} wanted to offer the 273 4-Barrel in 'two combinations' for the 1965 Models.
The 273/225 HP {which was the original 273/235 'Commando'}.
And a 273/235 HP 'Commando-HP',
Which was to have factory installed 'Forged-True' 11.5-1 Lightweight Pistons, Chrome Oil Rings
and TRW Bearings.
And with the #3447 Carter AFB {600 CFM} with a 1 7/16" Primary and 1 11/16" Secondary
mounted on the stock 273 Barrel cast iron Intake, but with the bore holes cut out for an open-plenum.
