1978 MGB GT V8

Highlights

  • An eye-catching “Sebring styled” MGB GT fitted with a rebuilt 3.5L V8 engine
  • With lots of recent expenditure this is reported to be a ready to enjoy example
  • Complete with a lightly customised and retrimmed interior

The Appeal

As early as 1971 racing driver and engineer, Ken Costello, had fitted the BMC version of the Buick 3.5L V8 engine into the nose of an MGB. Ken understood two key facts that led to this experiment. The MGB’s engine bay had been designed to house a bigger V4 engine that never made production and that the alloy V8 was essentially no heavier than the standard B-series engine. Such was the success of Costello’s V8 cars that British Leyland launched their own V8 MGB GT in 1973. The ample torque of the V8 was widely regarded to have transformed the MGB GT’s driving dynamics.
This car, although starting life as a standard MGB GT, has subsequently benefitted from a number of modifications and upgrades. A key one being the fitting of a Rover 3.5L V8 engine mated to a five-speed gearbox. Other cosmetic, Sebring style modifications result in a BGT that looks as good as it drives.

Summary

In the realms of classic MGs of the 1970’s, the MGB GT V8 is somewhat of a sweet spot. The muscular 3.5L V8 took the slightly anaemic 1,800cc version and put some fire in its belly. Although this is not a factory V8 BGT it has clearly been professionally attended to endowing it with all the key attributes associated with the V8 cars.
The modifications to this model really help set it apart from more humdrum examples. Its nicely resolved livery combined with Sebring style upgrades hark back to many competition orientated MGs of the past. This hasn’t seemed to have detracted from the eminent usability of this example, however, with the owner reporting it as “understated but powerful.” To get behind the wheel of this uniquely presented and modified example, be sure to bid early.
