The Austin-Healey 100 had begun to decline in popularity by the mid-1950s so was re-vamped as the 100/6, despite its initial success. BMC’s 2.6-litre C-series six replacing the original four-cylinder Austin Atlantic engine. In 100-6 tune the pushrod straight six produced 102bhp – 12bhp more than its predecessor – though the inevitable weight gain meant that there was little if any improvement in performance. In 1957 an improved ‘six-port’ engine became available, and this 117bhp unit was fitted to all the newly introduced BN6 two-seat roadsters.

This 100/6 was rebuilt by renowned marque specialists Denis Welch Motorsport and sold to Andrew Usher, a well-known campaigner of racing Healeys in the early 1980s. It incorporates all of the most desirable Welch performance upgrades for a 100/6, including a lightweight aluminium body (with steel bonnet). ‘MSV 500’ was sold by Denis Welch to his brother-in-law (the previous owner) in 1986 and for the next 26 years was continuously upgraded and maintained by Denis Welch.

Incorporating a 3-litre cylinder block, the engine has been built to Stage 3 ‘fast road’ specification. The latter includes a blueprinted, lightened and balanced flywheel; gas-flowed cylinder head; forged pistons; SU 2″ carburettors; Welch inlet and exhaust manifolds; high-flow aluminium radiator; ITG competition air filters; fully baffled works-type sump; competition clutch; electric fuel pumps; side-exit competition exhaust; spin-on oil filter; and Kenlowe electric fan with manual override. The engine produces an estimated 175-185bhp at the flywheel, which combined with the lightweight body makes for a car with breathtaking performance.

The car looks absolutely stunning in its Lobelia Blue livery with white number-roundels, the ‘MSV 500’ numberplate and trim in blue leather. The car is also fitted with the rare, yet extremely comfortable, period-correct lightweight seats in 100S ‘Le Mans’ style. This Austin-Healey also boasts a new soft-top in blue mohair and is fitted with a period-correct hardtop.

Ideally suited to a wide variety of prestigious historic motor sports events, this unique Austin-Healey 100/6 would be equally at home, on a trip to Goodwood or Classic Le Mans especially as it’s fitted with a Monit rally trip-meter and Willans safety harness.
