The first weekend of June saw Geoffrey Horton take his Jaguar XK140 FHC seen above to the San Marino Motor Classic.

Among the US vehicles on display was this 1921 Duesenberg Straight Eight also known as the Model A first seen in 1920 but which did not go into production until 1921 by which time the motor had been fitted with an overhead camshaft.

Powered by a 6.3 litre / 384 cui L head straight 8 the 1932 Chrysler Imperial was also marketed as the ‘Imperial 8’.

In 1957 Ford built two competition Thunderbirds with supercharged Lincoln motors and Jaguar transmissions, of which I believe only one original, the #98, still exists. The car above appears to be a copy of the #99 which was dubbed the Battlebird by the media back in the day.

I had great fun trying to figure out if the vehicle above was either a 57′ Chevrolet or a Cadillac and it turns out to be a bit of both. Cadillac owner Ruben Allender came up with the idea of offering a $1,000 conversion to turn a Chevrolet into a Cadillac in 1956. It is thought 20 examples were built in the first year and possibly 16 more in 1957 when production ceased.

Finally for today I’ll leave you with this delicious vehicle labelled as a “1961 Indy Roadster”. The #41 was carried by Johnny Boyd’s Leader Card 500 Roadster sponsored Watson Offy in the 1961 Indy 500. Johnny qualified 20th and retired at just over half distance with a broken clutch.

My thanks to Geoffrey Horton and Paul McNabb for sharing today’s photographs more of which will appear on Tuesday and Friday next week.

Thanks for joining me on this “Americana” edition of “Gettin’ a li’l psycho on tyres” I hope you will join me again for Ferrari Friday tomorrow. Don’t forget to come back now !
