An Iso Grifo A3/C For Sale

by Mike –

The Iso Grifo A3/C is a rare car and they do not come up for sale very often. So, I get excited when one is for sale.

1964 Iso Grifo A3/C No. 0217

The competition version of the Grifo was named Iso Grifo A3/C (C for Corsa). This is a different body design than the A3/L (L for Lusso) and Giorgetto Giugiaro, of Bertone, was again responsible for the styling.

It has a lightweight riveted aluminum body and everything about this car was designed to win the 24 Hours of Le Mans. It is low to the ground, lightweight, used under the car aerodynamics and the engine was pushed far back in the chassis resulting in a front-mid-engine placement.

The engine is placed so far back that the distributor is under the dashboard and a panel on the dashboard is removed to access the distributor.

The result is almost a 50/50 weight distribution front to back. The doorsills are also gas tanks for improved weight distribution. Including the rear tank this car holds 35 gallons of fuel.
The Corvette 327 cid engine had a Bizzarrini designed intake manifold with four Weber carburetors, producing more than 400 bhp. The Iso Grifo A3/C has a top speed of 170 MPH.

There were 22 of the A3/C models made under the Iso Grifo name and they were raced in Europe and the United States.

This car has a few thousand rivets holding the alloy body panels together. At the time this was a quick and inexpensive way to put the body together. Today it is just cool.

The Iso Grifo A3/C became the Bizzarrini GT 5300 when Giotto Bizzarrini split with Renzo Rivolta.
