Ferrari 250-series schematic drawings created by GTO Engineering

With no such factory sets, LA company develops its own for iconic V12 models


GTO Engineering has launched the world’s first set of technical schematic drawings of the iconic 1959-64 Ferrari 250 series, from the legendary 250 GTO race cars to the luxury-performance GT and sports cars of the series.

Such schematics were not created at the time by the Ferrari factory, according to a news release from GTO Engineering, but now a complete set of drawings showing the components of the V12-powered 250 series cars will be available in digital and printed format, available on the GTO Parts website.

The drawings provide a list of parts numbers

“Each schematic drawing focuses on a certain area of the Ferrari 250, from brakes and suspension to engine and gearbox, and correlates to parts that are manufactured or sourced by the GTO Parts team,” the news release says.

“They will be available via GTO Parts’ website and a printed catalogue, with a total of 33 drawings over 80 pages (if in printed format) available, with hundreds of components and correlating part numbers listed.”

GTO Parts was created in 1996 by Mark Lyon, the founder and managing director of GTO Engineering in Los Angeles and England, and is recognized as a leading parts supplier and specialist for classic and modern Ferraris worldwide. The company “fabricates bespoke, hand-crafted parts in its in-house machine shop, as well as engines in its dedicated workshops, such as the 250-series Colombo V12s and various other iterations of the Ferrari V12 engine,” the release notes. 

While GTO Parts has offered schematics for other series of Ferraris, the new set for the 250 lineage adds an important piece of research information for owners and restorers of these classic models, which are among the most-valuable collector cars in the world.

High-tech systems were used to create the schematic drawing set

 “Seeing the complete schematics for the 250 series of Ferraris finished is an emotional feeling,” Lyon said in the release. “I remember, before we embarked upon this project, adapting the schematics for a Ferrari 330 with a pencil and trying to match-up the part numbers. It was a real mess, and only made sense to me. That was when there were parts available on the shelf in the late ‘80s, but components soon became unavailable not long after that, so the parts side was void.

“Ever since that day, with the annotated Ferrari 330 schematics drawings, I’ve wanted to be able to create from scratch our own technical drawings for the 250 series. Today, with our dedicated in-house CAD team, modern technology, engineering know-how and the GTO Parts business, we knew that as a Ferrari specialist we were well-placed to rectify this.

“There’s also a key sense of achievement in that every component within the schematics, matches a valid part number that we can sell to our customers.”

GTO Parts is preparing to open its European base this Spring in Modena, Italy, offering an array of original and OEM specialist Ferrari parts, as well as components for other classic Italian cars.
