ENGINE
The car was supplied to Aston Workshop with its replacement engine, but both the engine block and cylinder head were found to have serious defects and new replacements therefore sourced. The new engine block also benefits from new pistons, con-rods, liners with copper sealing rings, crankshaft and bearing housings while the oil galleries have been increased in diameter. The cylinder head is fitted with new valves, guides, collets, springs and core plugs as well as camshafts to fast-road specification. The carburettors supplied with the vehicle have been restored. Careful modifications to ensure longevity and reliability include an uprated oil pump, electronic ignition and a geared-type starter motor.
Both the head and block have been pressure tested to 40psi and the finished unit carefully run-in on our dyno, where it recorded strong power. The engine produces 175 BHP and 200 ft pounds of torque and an even spread of torque throughout the rev range. Crucially, Aston Workshop rebuilds eliminate the oil leaks common to these engines in period, and none were detected throughout this rigorous testing stage.
The transmission was fully steam-cleaned, reconditioned and overhauled and the clutch uprated to DB5 specification, with the original flywheel refreshed with a new ring gear.
