Since I have more than a passing interest in the SCB engine, I started looking into just how many were built. I found a post from Bob Ilich in Oz stating that three were built, including the one in his car. I looked into the F2 register for '67 and found two cars:

Brabham BT-16 F2-23-65 Driver Brian Redman Entrant David Bridges
Cooper T83 F3-1-66 Drivers David Darby/Brian Myers Entrants same

I then found a Palliser/SCB driven by Hugh Dibley in a Formula Libre race in '67, which makes 3 engines.

Bob Ilich took delivery of Brabham BT-21B-16 with an SCB, I assume in '68, and took it to Australia where it remains today, still with the SCB.

There is mention of another BT-21B with an SCB used by Louis Parsons in Formual Libre racing in '69-70.

I figure the engines from the BT-21s could have come from earlier cars, so there still might be only 3 engines.

Can anyone shed any additional light on this?
