Today’s photo album focuses on the Lola Chevrolet T70GT mk3B of 1969 that competed directly with the Group-4 Ford GT40s and Porsche 917s of the day, amongst others. Power came from a mid-mounted, naturally-aspirated, cast-iron/aluminium-alloy head 5L Chevrolet V8 drinking fuel through 4 Weber carburettors and producing 450 bhp with the aid of a Hewland LG600 5 speed manual.
The chassis featured an aluminium riveted and bonded monocoque and the body itself was fibreglass. Double wishbones, an anti-roll bar and coil springs over Koni adjustable shocks handled the suspension duties while Girling ventilated discs on all 4 corners took care of stopping its lightweight 800 kg mass.
The Lola raced in various endurance events such as Le Mans but was most notably effective on sprint events such as the highly-missed Can-Am series held in America. This pictured example is the ex-Sid Taylor car that dominated the endurance racing scenes in 1969-70…
Excellent onboard video from the 2011 Spa-francorchamps Classic…
And another vid of it clearing its mighty lungs – what a beast…!

There are few factory-derived racecars as tauntingly beautiful and purposely outlandish as the legendary Porsche 917K series. There’s just something about its purity of voilent speed and devilishly analogue nature that *pings* directly at the petrolheaded soul and has you searching for a YouTube fix at 2am…
The Porsche 917 was originally designed as a ‘long-tale’ (917LH) but seeing as how this initial version produced rather sketchy handling at high speeds, a shorter-tailed version (the 917K) was developed to cure the high-speed instabilities at the cost of a slightly lower top speed. Based on the Porsche 908, the 917 was conceived in an alarmingly short time of just 10 months (at great expense to Porsche) and made its debut win at the 1970 Le Mans – the first-ever overall win for Porsche. It followed this win up with a 2nd overall Le Mans win in ’71.
Power came from the monstrous Type 912 air-cooled flat-12 engine that ranged in size from 4.5, 4.9 and 5.0 litres producing upwards of 620 bhp. The dash to 60 would arrive in 2.3 seconds and 125 mph would be achived in a barely-believable 5.3 seconds… (!)
In the sorely-missed original Can-Am series (’66-’74) an insane turbocharged version dubbed the Porsche 917/30 produced well over 1,100 bhp and as much as 1,580 bhp when in qualifying tune… again, (!)
As an added little bonus, here we have a chart documenting every single 917 chassis ever made…
