| Modifying MGC |

The MGC has become as sought after and almost as valuable as the infamous Austin-Healey, and consequently there is a selection of subtle updates and modifications available for the model. Words & pictures: Rob Hawkins
The straight-six engined MGC seemed destined to have a promising career when it was launched in 1967 as a GT and roadster. Replacing the Austin-Healey and using the same 2912cc engine, the MGC offered over 50% more power than the smaller four-cylinder MGB (145bhp instead of the MGB’s 95bhp), resulting in a top speed of 120mph and a 0-60mph time of 10 seconds.
Externally, the MGC could be told apart from the MGB thanks to a huge bulge in the bonnet to help clear the radiator and SU carbs. Underneath, the engine bay and floorpan had been revised to accommodate the larger and heavier straight-six (it’s 209lb heavier than the lead weight B-series). The suspension was also updated with torsion bars and telescopic dampers at the front, but a traditional MGB set-up at the rear using leaf springs and lever arm dampers to control a live axle.
Although the ingredients of the MGC were tempting, its additional weight and the emergence of the lighter Rover V8 as a better powerplant resulted in a short production life for the model. According to the record books, 8999 MGCs were produced up to August 1969, although some were still being registered in early 1970. The split between roadsters and GTs was almost 50:50, with a greater proportion of roadsters being exported. According to the DVLA, there are nearly half of the roadsters remaining in the UK and only a quarter of the GTs, although re-imported examples may have boosted these figures.
The modification market for the MGC has been overshadowed by the MGB market, but the history of the MGC and its involvement with racing derivatives such as the Sebring and GTS models has helped to keep it alive. Specialists including Doug Smith at MG Motorsport have also helped to fly the flag for this car and continue to promote it through racing, whilst many others have ensured that the availability and supply of standard parts remains comprehensive.
As a general rule, most MGC owners are not quite so heavily into modifying their cars as those who own MGBs, but many are inspired to recreate their MGCs as traditional race cars. Fortunately, the MGC’s straight-six has lots of tuning potential, and the brakes and suspension can be similarly upgraded. The following pages outline many of the popular modifications available for both the roadster and GT versions of the MGC. As ever, our advertisers will be happy and able to give further advice.
