On October 5th Geoffrey Horton took his Jaguar XK 140 to Niello Concours at Serrano where it was shown in the special display class.

Any one interested in what is under the hood of Geffrey’s Jaguar can see it by following this link.

Today’s post will focus on what was lurking under the hood of some of the other vehicles on display, above the 1911 National Indy 500 car only had 4 cylinders but with a displacement of 7.5 litres / 460 cui they still packed a 100 hp punch.

I beleive this is the third appearance of this particular 1951 Allard K2 on this blog, but the first appearance of it’s 5.4 litre / 331 cui Cadillac overhead valve motor with three original Stromberg carburetors that produce around 160 hp.

The 281st, off the production line, 1956 Plymouth Fury above boasts a 5 litre / 303 cui polyspherical head V8 with optional twin 4 barrel carburetors which combined to produce 270hp.

For 1960 Chrysler introduced the 6.8 litre / 413 cui wedge motor for the 300F seen above. To maximise power in low to mid rpm range the motor was fitted with tuned 30 inch intake pipes which were fed by the carburetors from opposite sides.
The air resonances inside the air intake pipes helped to force air into the cylinders at low to mid range rpm and thus increase the power which topped out at 375hp.

Not completely off topic I was reading some information about the early days of racing recently and discovered that while Voiturettes were generally restricted to 1.5 litre / 91.5 cui motors there was a smaller class known as Cycle Cars which were restricted to 1.1 litres / 67.1 cui which would make the much later 1963 Formula Junior Lotus 27 above the equivalent of a cycle car in Veteran times. The motor for this Lotus is clearly a Ford production block with a Cosworth head. Power for these motors has risen from 36hp in original side valve production form to 115 hp quoted by some tuners for a competitive Formula Junior with the Cosworth head.

In late 1963 Lotus built the last Lotus 19 B chassis #966 uniquely powered with a 4 carburetor 4.7 litre / 289 Ford V8 motor for Dan Gurney. The car was quick, but unreliable and Dan never recorded a win with it although it’s next owner Steve Diulo managed a win at the SCCA Willow springs race in December 1965. The cars last appearance was at Texas International Speedway in November 1969 where Bruce Campbell was running but unclassified in chassis #966 by now rebranded as a BVC Mk 1 and with a Chevrolet motor installed.

Finally, for this week, above is another Ford V8 this time a 306hp 4.7 litre Shelby tuned Ford HiPo 289 inside one of the 252 “carry over” 1965 Shelby Mustang 350 GT’s which feature ’65 Ford VIN numbers and ’66 Shelby VIN numbers.

My thanks to Geoffrey Horton once again for sharing his photographs from the California Concours d’Elegance scene through the year.

Thanks for joining me on this “Under The Hood Details” edition of “Gettin’ a li’l psychoontyres” I hope you will join me again tomorrow when I’ll be looking at a 3 ton pickup that gets up to 60mph from rest in just 5 seconds. Don’t forget to come back now !
