In 1966, when the new Grand Prix formula for 3-litre un-supercharged or 1.5-litre supercharged cars came into effect, engine designers turned to many different types of engine configuration and cylinder head layout in their endeavours to produce competitive Formula 1 engines for the new formula. One engine stood out for its advanced concept in cylinder head design, featuring four valves per cylinder at a narrow valve-included angle of 30° in a shallow pent-roof combustion chamber atop oversquare-dimensioned cylinders with flat top pistons. That engine was the 3-litre Gurney-Weslake Type 58 V12 designed and built by Weslake & Company Ltd. in England to power Dan Gurney's All American Racers, Eagle Formula 1 car. Ron Rex tells us all.

In a 2020 historic motorsport calendar blighted by postponements and cancellations, the Historic Grand Prix at Zandvoort proved to be a true miracle. It took place on the original date, and a crowd was present too – which had to adhere to strict social-distancing rules but wasn’t forced to wear face protection. Half of the original programme was slashed due to the UK’s strict quarantine measures but fortunately four Masters grids did arrive from England and the rest of Europe, adding up to three national grids and four grids from Germany that saved the show. Let’s look at what happened.

The 1948 Indy 500 could have been a hugely controversial race if Duke Nalon's Novi hadn't been forced to make an extra pitstop for fuel while leading the race - while in fact he didn't lead the race! The thing was, IMS Timing & Scoring had made a costly error and handed back a lap to Mauri Rose's winning Blue Crown Special, but only after reviewing all the official data when the race was done and dusted. So would Nalon have gone on to cross the line in first position, only to have the win taken from him after the victory ceremony? It's an intriguing question and, as Indycar history showed in later years, not as much of a freak occurrence as officialdom would like it to be, as for instance Billy Boat and Arie Luyendijk can testify - with Boat's IRL victory at the Texas Speedway in 1997 stripped from him and handed to the Dutchman the day after the race. Henri Greuter decided to investigate - would this indeed have happened in 1948? Or is this a myth that needs busting? We give the answers precisely 72 years after the day that Duke Nalon and his legendary Novi drove their first laps together on the Indianapolis Motor Speedway in preparation for the 1948 race.
