History: The ISO company was founded by Renzo Rivolta,
an industrialist best known for making refrigerators, motor
scooters and the Isetta bubble car, which he later licensed
to BMW. The first high performance car made by ISO was the
very successful 2 door Rivolta. This was followed by the fastback
Grifo which grew out of the earlier Rivolta that was engineered
by Giotto Bizzarrini, designed by Bertone (Giugiaro) and powered
by Corvette 327 V8. Using the same Bizzarrini designed unit-body/monocoque
underpinnings, Bertone designed a sleek 2 seat berlinetta.
With the prototype Grifo A3L receiving critical acclaim, a
production version appeared 18 months later in 1965. A higher
powered, limited production version known as the Grifo 7 Litre
using Corvette 427, 400 bhp engines (usually in combination
with 4-speed gearboxes or 3 speed automatics, although a few
were fitted with a ZF 5-speed), became an option in late 1968.
The 5-speed big block version was the fastest of all Grifos
and, in the late sixties was recognized as the fastest production
car in the world. A covered headlight Series II Grifo appeared
in 1970. Most Series II cars were Ford Cleveland 351 powered,
although the big block cars stayed with Corvette power, albeit
the 454, which provided more low end torque, but lower speed
at the top end.
Production: In total, 413 Grifos of all types
were built before ISO went out of business in 1974, another
victim of the 1973 energy crisis. 66 Corvette 427 powered
Series I cars were built and 4 Series II cars with same engine.
20 Series II cars were built using the Corvette 454 engine.
This car took first place in its class when shown
at Pebble Beach in 1999.
