The JW Gulf boys relax before the off, the winning duo were Pedro Rodriguez and Leo Kinnunen…
There was only one Porsche 917 amongst the first nine cars home at the duration of the Monza endurance classic on 25 April but the German flat-12 was first, Pedro Rodriguez and Leo Kinnunen were happy winners.
Three Ferrari 512S followed them home, the Ignazio Giunti/Nino Vaccarella/Chris Amon Spyder 1.5 minutes adrift of the John Wyer Porsche.
It wasn’t a happy season for Ferrari in sportscars. Supremely competitive in F1 with the first of its flat-12 engined cars, the 312B, the 5 litre V12 512S really didn’t receive the development it needed to knock off the Porsches.
The German cars mainly raced at 4.5 litres in capacity that year but it was still more than enough. A win at Sebring in the second round of the Manufacturers Championship was Ferrari’s best result, and the flat-8 3 litre, nimble, light Porsche 908/3 mopped up on the tight, twisty circuits unsuited to the 917. The dudes from Stuttgart had the game well covered.

Seppi in conversation, and for the horologists he is sporting a nice Heuer Autavia chronograph (Schlegelmilch)
The speed of Ferrari’s evolved 512S, the 512M was clear at the Osterreichring 1000 Km in October, so 1971 looked to be a great battle of two amazing 5 litre cars but effectively the Scuderia waved a white surrender flag before the seasons commencement.
They chose to race a new 3 litre flat-12 engined prototype, the 312P in 1971 with an eye to the rule change to cars of that capacity in 1972, rather than the factory race the 512M.
The Ferrari privateers did their best against the Panzers but it was ineffective, the speed of the beautifully prepared and superbly Mark Donohue driven Penske 512M duly noted. The 1971 endurance season could have been the greatest ever had Scuderia Ferrari raced those cars!
Back to Monza 1970. The other ‘works’ Porsches were well back- the JW 917K of Jo Siffert and Brian Redman finished 12th, the Porsche Salzburg 917K’s of Vic Elford/Kurt Ahrens DNF with puncture damage after 92 laps and the 1970 Le Mans winning combo of Hans Hermann and Richard Attwood were out with engine failure on lap 63.
Still there was strength in numbers, Pedro and Leo were there at the end, in front…
