The 383 4 Barrel was a midyear addition as my elderly
mind recalls.
I had a 343HP 62 Wagon for a while that was called the
"Orange Crate" that I bought from the Foley Brothers and
it held the F/SA National Record.
A lot of you guys would be surprised to know there was never
a 343HP Dual Quad Solid Lifter combination ever available from
Mopar.
It was a Make Believe car or what we used to call a "paper car".
Mopar got together with George at Clay Smith Cams and they together dreamed
up an engine with his Solid Camshaft that was the biggest that would
fit without crashing the valves into the pistons. It incorporated the heads
of a Chrysler 300 with 208 and 175 valves and a small combustion chambers.
Later the head superseded into the 67 915HP replacement heads "according"
to Chrysler.
I have several friends that race these even today in Stock Eliminator and re
well into the 10 Second range @ well over 120MPH.
The later 383s rated as high as 335 HP are nowhere near the power of the 62
and the cars are heavier. If you run mid 11 Seconds with one of those you
are doing well. I have tested and raced them both over the years.
I am sure I have bored everyone by now.
