A Special note from the Webmaster:
visit to the GJA shop to drop off our
engine block for machining, we were
lucky enough to get to meet Gary Johns
the man himself in person!
In the machine service business for
over 40 years, Mr. Johns is responsible
for building countless stock, performance,
hot rod and competition engines over
the many years that dominated in whatever
category they were used in.
Having some health issues in recent
months, Mr. Johns hasn't been able to
spend as much time as he normally likes
to working with customers and vendors
in the shop.
Let me tell you -the man' is sharp as
a tack! Whether it was about a piece
of equipment in the shop or an old intake
used for decoration hanging around the
ceiling area of the shop, he could rattle
off a full explanation of what it did,
what it came off of -or even how it
came to be in his shop!
Famous for the dependability and longevity
of his engines while making big horsepower,
and to be able to meet Mr. Johns and
get to spend a few minutes discussing
engines, racing and the GJA history
-was something this webmaster will never
forget. Impressive shop, impressive
