The First 1967 383 A-Body, 'Barracuda or Mr. Norms's Dart'

Correct Mr. Kosmic,

In 1968, the 383 in the Barracuda was re-rated to 300 Horsepower from the previous
years 'anemic' 280 HP rating.

Changes,
A) The piston height was now .014 (above the deck), instead of .007 (below the deck)
B) The #2843906 casting Cylinder Heads with open-chamber design (79.5 cc's), 10% larger port area,
and larger exhaust valves {1.74"} were now installed.
C) The previous years Camshaft and Valve Train were still utilized.
D) An improved left side (driver side) exhaust manifold was designed.
E) The right (passenger side) exhaust manifold had an improved angle.
F) The exhauts manifolds were positioned closer to the engine, for increased inner-fenderwell clearance
G) The exhaust piping (primary pipes) had an improved design to provide for less
restriction in the exhaust-flow.
H) A new Intake manifold #2806301 with 10% greater branch and 50% more runner size was
installed.
I) A new Carter AVS Carburetor (625 CFM) was utilized.
J) An unsilenced air cleaner replaced the standard unit.

Note; The difference between the 68' Road Runner/Super Bee 383/335 HP
engine and the Barracuda 383/300 HP, was,
A) Oil pan windage tray
B) Camshaft, as the 383/335 HP received the 440 Camshaft and Valve Train
C) 440 Exhaust Manifolds and Exhaust Piping
