Morton rounds Turn 9 during Friday morning's dreary, wet practice.

This is a unique RS61.  It has a wheelbase four inches longer than standard to allow for mounting Porsche's then-experimental 2-liter flat-8 engine for testing.  Bob Holbert bought the car and campaigned it with the usual 1700cc. flat-4, but he liked the extra wheelbase length as he felt it improved the car's handling.

The car is now powered by the very rare flat-8.
