1961→1962 Austin-Healey 3000 MKII BN7
In May of 1961 BMC upgraded their flagship model with three SU HS4 carburetors, modified valve springs and a new camshaft. Called the MKII, it was an alternative to the Triumph TR3A or Jaguar E-Type.
The MKII was initially offered as an occasional 4-seat roadster called the BT7 or the 2-seat variant from known as the BN7. Both versions used flat front windscreens and detachable side curtains in the style of a roadster. The rear panel of the BT7 was cut out much deeper towards the truck to make room of the small jumper seats in the rear. As a result, almost all the road race and rally cars were built on the BN7 platform.
Later cars came equipped with a center-located top-loader transmission and a fiberglass transmission tunnel. Of these the BN7, top-loader is an especially rare and desirable combination.
Like the earlier 3000s, the MKII featured BMC’s C-Series six-cylinder engine with a 4-speed + overdrive gearbox. It used a separate ladder-type frame and a steel body.
Production of the MKII BN7 was very limited to only 355 cars. The BT7 4-seat roadster vastly outsold it at 5,096 units. A BT7 with hardtop and overdrive cost £1362 including the hefty British taxes.
MKII configuration changed significantly in 1962 with the introduction of the BJ7 Sports Convertible. It replaced both models with a fully-collapsible soft top, wind-up windows and a curved front window. This modernized the car substantially and the BJ7 is more desirable as a touring car.
Options on the MKII included 15×4 chromed wire wheels, a brake servo system and a tonneau cover that could be opened for just the driver.
