Auction description:
Lot 225: 1955 Jaguar XK140 Competition Coupé
Collectors' Motor Cars, Bonhams (30th July 2005)
Overview
Attractively finished in Ecosse Blue with grey/black interior, this competition-prepared XK140 is offered fresh from a complete ‘chassis up’ rebuild of coachwork and mechanicals undertaken for the 2005 season. Its specification highlights include a seam-welded chassis, alloy doors, floors and gearbox tunnel, and a lowered engine. A Dave Butcher-prepared 3.8-litre unit equipped with triple SU carburettors, the latter is mated to a four-speed E-Type gearbox (with extended lever linkage) via a triple-plate clutch. The running gear also has been extensively modified, featuring rack-and-pinion steering (lowered in the chassis), up-rated front anti-roll bar, fully adjustable AVO shock absorbers, 4-pot front and XJ6 rear brake calipers, and Dana-rebuilt back axle. Other noteworthy features include an up-rated water pump, special radiator and header tank system, and Mallory twin distributor. Eligible for a wide variety of historic motorsport classes and events - including the JEC Challenge, HSCC, HRS, Top Hat, etc - the vehicle is described by the private vendor as in very good condition throughout and offered with old-style logbook, current MoT/road fund licence and Swansea V5 registration document.

Auction description:
Race Retro Classic Car Sale
1955 Jaguar XK140 Competition Coupe
Lot No.: 165
Registration: RDA 401
Chassis Number: S804523
Engine Number: 7B6421/8
CC: 3800cc
Year of Manufacture: 1955
Sold for (£): Unsold

The potent race prepared XK140 Fixed head coupé offered for sale today is a fine competitor and 2007 XK Championship Winner at the hands of a faithful XK pilot, Trevor Groom. Engine notes from respected engineer, Dave Butcher, confirm dyno test when new of 300bhp at 6000rpm attributed to engine upgrades, which included JE Pistons, tuftrided crank, series III rods, lightened flywheel, triple green clutch, .450"lift cams and a 1 7/8 gas flowed head.

Now reluctantly offered for sale as a result of the owner's interests diversifying into other racing Series, this widely eligible and competitive entrant could be yours at a fraction of the original build cost. The recipient of continued post-race maintenance, 'RDA 401' has most recently received attention to the suspension including re-setting the AVO dampers on AVO's dyno and had new rear leaf springs bespoke made. Recent changes made in national XK racing to offer increased eligibility and significantly larger grids for independent entrants in series such as the 'XK Challenge' and '50's Sports Cars', means there's never been a better time to enter the sport.

Whether you're a seasoned veteran of the race track, or a novice looking to step in from the side-lines, 'RDA 401' is a fabulous motor car with winning credentials for you to join the grid.

This clip shows 'RDA 401' leading an XJ for much of the 2008 Silverstone Classic Race, driven by Trevor Groom:
