1975 March Formula Atlantic, FC, F3

ex-Bob Welch SCCA Runoffs Car

Sale Pending


This is the ex-Bob Welch March. It was brought to the U.S. by Welch and raced in SCCA starting in 1976. It’s prior history, if any, is yet unknown. Welch had the car set up in Formula C configuration and went to the SCCA Runoffs with it.

You can see from the photos below that Welch and his team had to do a last minute engine change at the Runoffs to make the show. The car still has its original SCCA logbook.

After the Welch era, the car was later acquired by its current owner. The car was still in it original Welch configuration and livery, but less engine and gearbox. See the photos below.

The current owner, who owns a race prep shop, restored the March. The original tub, AM753-50, was replaced during restoration with tub number 773:32, which was in virtually new condition, and came with the car at the time the current owner purchased it. The original Welch bits were restored, upgraded, and reassembled on the new tub. A fresh Hank Clarkson 1600 c.c. Formula Atlantic spec Cosworth BDA was installed along with a Hewland FT200 gearbox.


There are now three weekends on the Clarkson BDA and the Hewland FT 200. The gearbox was most recently rebuilt by J and J Racing, Ltd., in Bally, PA.  The car’s last outing was at Mont Tremblant, Canada, in 2019.

Here are some other features:

Stainless steel exhaust

New fuel cell

Electromotive Ignition

Original March wheels

Koni 8211 shocks, rebuilt by Truechoice

Rebuilt Monocoque

Long wheelbase engine subframe

Suspension newly plated

New heim joints

The car is currently located on the U.S. East Coast.

Mid-1970’s Marches are Formula Atlantic icons. They won championships. They  launched the career of Gilles Villenueve. Vittorio Brambilla won at Trois-Rivieres, in a 75B. Bobby Rahal won the SCCA Runoffs in the same 75B. This particular 1975 March offered here raced in the SCCA Runoffs in Formula C configuration before its conversion to 75B specs with its 1600 BDA and Hewland FT200.

As many of us know, now is a great time to pick up a flat bottom Formula Atlantic. You can race flat bottom Formula Atlantics with the  Masters Formula Atlantic Plus Series. You can race them with CSRG, VARA, SVRA, CVAR, etc. just to name a few. These are also cars that get invited to events such as Long Beach and to be in the support race for the U.S. Grand Prix in Austin. That’s a lot of bucket-list racing value for only $50,000.
