The car’s mechanical specification includes the gloriously named Avanti R1 Jet Thrust engine, whose eight cylinders have been proven to develop a whopping 296bhp and 315lb/ft of torque.
The engine’s specification includes JE pistons, Sealed Power zero-gap piston rings, Carillo connecting rods and Chevy P bearings, an OE forged crankshaft, gas-flowed cylinder heads, stainless-steel inlet and exhaust valves, a Doug Herbert camshaft with solid lifters, aluminium camshaft gear, Manton pushrods, a vibration-free custom balancer, a modified and baffled sump, an aluminium inlet manifold fitted with a new Carter 600cfm AFB carburettor, and an MSD 6 with an adjustable rev limiter.
Auxiliary components include an MSD 6 ignition system, MSB HT leads, a Pertronix pickup distributor, BMRS hoses and fittings, a 24-row oil cooler and electric fan, an aluminium catch tank, a WOSP starter motor, and cast aluminium Studebaker rocker covers.
The attention to detail throughout the car is remarkable and no component better illustrates that than the custom-fabricated, Tig-welded, 2½-inch twin-pipe stainless-steel exhaust system that includes an O2 sensor. The full exhaust system gives a decibel reading of 92 – and it looks as good as it sounds.
The engine feeds it considerable power to the rear axle via a Helix clutch, billet flywheel, an OE T10 gearbox rebuilt with a close ratio gearset, a Hurst shifter, and a Dana 44 OE rear axle fitted with a Gripper differential and beefed-up half shafts.
And yet, power is nothing without control so the Lark is also fitted with optimized front and rear suspension with custom Gaz adjustable dampers on all four corners and an in-house 1¼-inch front anti-roll bar constructed of EN16T and 3/8-inch rod ends.
Braking is courtesy of a heavily modified system comprising an RRC bias pedal box using Girling master cylinders and an adjustable pressure regulator, Brown and Miller flexible front and rear brake lines with copper nickel hard lines, OE Dunlop front calipers fitted with a BG Developments piston set and Pagid RS race pads, and eleven-inch OE finned drum brakes on the rear fitted with competition-spec brake shoes.
