- One owner since January 1960

- Extensively developed and improved by its long-term engineering consultant owner

This fascinating left-hand drive Twin-Cam Roadster has had just one owner since January 1960 - the now retired engineering consultant Tom Boyce who, among other things, is known for successfully co-driving Jean Denton in an MGB on the 1979 London to Sydney Marathon. This adventure gave him access to MG's engineering department as well as its competition parts bin. This now much-developed MGA is the embodiment of the knowledge and contacts he accrued.

'UHM 305' vacated the Abingdon production line in August 1959 and was briefly driven in the UK by it first owner, an A. Weed Esq., before being exported to Canada where it was acquired by Boyce. Well used - even by 1968 it had notched up c.120,000 miles - it had spells in Canada, the UK and the US before finally returning to these shores in 1992. It was in the late 1990s/early 2000s that the MG was treated to a comprehensive body-off restoration, since when it has had little use due the owner's failing health.

The Twin-Cam's countless upgrades include: a balanced 1790cc B-Series engine that features Dellorto 45mm twin-choke carburettors feeding a gas-flowed, big-valve cylinder head; competition MGB block with nitrided steel cross-drilled crankshaft; 1750cc Alfa Romeo pistons; baffled sump and external oil cooler; large Ford-sourced clutch mounted on lightened flywheel; Lumenition electronic ignition linked to a competition distributor; MGB close-ratio gear set; 4.88:1 final drive, multi-leaf MGB competition springs, competition drive shafts and anti-tramp bars; MGB front springs, competition dampers; larger radiator; alloy-coiled starter and dynamo; 6-inch rims on standard wheel centres; Jaguar E-Type three-eared spinners; stainless steel exhaust system with straight-through silencer.

The vendor currently views the bodywork, Blue paintwork, Red-piped Black interior trim, engine and manual gearbox as all being in 'good' order and is offering the MG complete with very comprehensive history file.

PLEASE NOTE: The vendor informs us that this vehicle's clutch is 'dragging' when engaging first gear and reverse gears.
