Wildcat low-profile injection manifold with eight throttle bodies, Wildcat Stage I ‘high port’ cylinder heads with stainless steel valves and tungsten valve seats. Wildcat roller rockers, Crane 248 camshaft, hollow chrome molybdenum pushrods, Wildcat solid lifters, ITG air filters, Cloyes duplex roller timing chain, lightened steel flywheel and a Helix heavy duty clutch.  Emerald K3 ECU, distributor-less ignition, Poly-V ancillary drives, heavy duty alternator and a high-torque starter motor. It produces a tractable 345 bhp and 327 lb/ft torque @5750 rpm.

Ken was a long-time admirer of the work of Ian Richardson of Wildcat Engineering, 'the best in the business', he used to say, but major engine re-working aside, he never really gave up on trying to maximise the potential of the classic MGB.

  • Electric windows

  • Full leather upholstery

  • Golde mohair sunroof with West of England cloth headlining

  • Stainless mesh Costello Mk III radiator grille
