1971 Chevron B20 Formula Atlantic - SOLD

This is now SOLD. Search for similar items.


This car came from the US to Europe about 10 years ago. Fitted
with what is said to be a long stroke BD it was actively racing up to
about 6 years ago. Then owner then lost interest and the car has been
stored in far from ideal conditions, resulting in some oxidation and damage
from the elements. The gear ratios were removed for use in another car
and the case not closed, so the bearings and remaining gears may have
suffered damage. The engine is said to have a problem with a
liner but is complete and was running. The left side of the tub has what appears to be
a wheel ding in the skin.


The prototyp B20, the car was configured as a Formula B car with a Lotus twincam for the last year
of the North
American Formula B series and campaigned by American importer Fred Opert and driven by Bobby Brown and
Jim Grob. It was one of three Fred Opert cars and may have been the car that Bobby used to give the B20 it's first
win at Bogota, Columbia, on February 27, 1972.
