Test fit of the 7.50-inch diameter pistons

The Goodwood Festival of Speed is being held next week in the UK on June 26-29, and Duncan Pittaway and his helpers Bruce and Tucker are working very hard to get the S.76 Fiat ready and there on time. Stefan Marjoram was at Duncan’s shop on the weekend of June 8-9th and took this set of photos showing the installation of the intake valves, connecting rods, pistons, the block and the s.o.h.c. assembly.

The huge four cylinder engine has a 7.5-inch bore x 9.843-inch stroke with a 1729 c.i.d. (28 liters) and it produces 300-h.p; each cylinder displaces 432 c.i. Many thanks to Duncan and Stefan for sharing the rare sight of the engine internals with us.

The Old Motor has been following this project for the last three-plus years and you can take a look back here at eight posts on the S.76 Fiat; there you can see many more of Stefan’s images and art, period photographs and as much information about the cars as can be found.

As of yesterday they were still on target, but have lots of plumbing and last minute details to attend to. Take a moment to visit with Stefan Marjoram and also learn all about The Festival of Speed. Stay tuned for a follow up.
