Our best advert...

We won't try to convince you why Bill Rawles Classic Cars is the best place to upgrade your Healey, our race cars speak for themselves with reliability and performance developed on the race tracks of Europe and technology filtered down into our road cars.

Do you really need modern alternatives? If you consider, during the Spa 6 Hours our race cars are on the limit for the full 6 Hours of racing, 6,500 rpm every lap, 2,280 gear changes, over 500 miles of racing, 2 fuel stops. Every lap the car is stopping from 130 mph to 58 mph at the end of the Kemmel Straight and to finish this grueling race many times, it is a wonder why one would need to remove original components and replace with modern alternatives, especially in a road car. Our race cars are built to FIA standard, only using what was available in period.

As well as numerous club racing wins, Bill Rawles Classic Cars machinery has also had notable success at national and international events such as: Spa 3 hours Class winners, 4th Overall. Spa 6 hours Class winners, 16th Overall. Castle Combe Autumn Classic, Winners. Zandvoort, Runners Up. Lap records at Zandvoort and Portimao.

100 to 100 'M' spec upgrade

Upgrade your standard 100 to M Spec and bring your 4 cylinder Healey alive. Around 640 'factory' cars were built and a further 500 'dealer fit' cars were converted. The upgrade to M spec is very involved and isn't just a case of a louvred bonnet and strap! M Spec pistons, cam shaft, fitted and colour matched louvred bonnet, strap, 1"3/4 SU's with M spec inlet manifold and cold air box. BN1's have up-rated roll bars and stiffer suspension. We will also fit M spec aluminum cylinder head. In most cases, this conversion results in a full engine rebuild. The full M Spec conversion from Bill Rawles Classic Cars, prices from £13,500.

Improve Reliability

If you're an enthusiast looking for some basic upgrades to improve your Healey we would recommend starting with a negative earth conversion, 12v plug socket for sat nav or charging (optional), fitment of a high torque starter motor, alternator conversion, spin on filter kit, solid state fuel pump, 5 blade plastic fan and our up-rated core radiator. This will give you more reliability, especially whist driving at night, the car will turn over and start easier and engine oil filtration will be improved. The 5 blade fan and up rated core rad will almost guarantee trouble free driving during the hot summer months. We would not recommend a kenlow fan as a replacement. Reliability can be vastly improved from £500 to £2,500. - Contact us for full details.

Improve Visibility

Improve your night driving and safety with our LED side light kit or Halogen head light upgrade. We will also replace your side lights to our unique package which enables earlier cars with single side lights to have LED front and rear combined yellow and red side, brake and indicator lights, also available for all classic cars.

Improve Interior
