In 1967 the basic 421 design's bore was increased to 4.12 in (105
mm). this gave a displacement of 426.61 cubic inches (6,990.9 cc)
or a 427. The 428 had the same 4 in (100 mm) stroke as the 421, yet
retained the 421's 3.25 in (83 mm) Main journal, and was produced
from 1967 to 1969. This engine produced 360 and 376 hp (268 and 280
kW) in 1967, 375 and 390 hp (280 and 291 kW) in 1968 and 360, 370
and 390 hp (270, 280 and 290 kW) in 1969. The crankshaft in the 428
also had a "N" cast on them as opposed to the 421's Armasteel. In
1969, Pontiac also used a revised crankshaft out of a Pearlitic
malleable-iron, although it still used the "N" casting letter. This
new material had stronger alloys in the iron. All 428 engines were
factory installed in large cars only. However, there were a few
dealers that would install a 428 in a customers GTO or Firebird for
higher power levels. All 428 cylinder heads received the 14 degree
valve angle, closed chamber only in 67 and open chamber 68 and
up.
It was replaced by the 455 for the 1970 model year.
