Just a quick note to say thanks for a fantastic product! A local garage– Maghull Four Wheel Drive – recently fitted a stage 1 head to my ex-military series 3 Marshall-bodied ambulance and what a difference! Although it will never be a ball of fire on the road, combined with electronic points, the difference is enormous – no more pedal to the floor to keep it at 50, no more shifting down to third or second on hills, no more queues of traffic building up behind - it easily keeps up with traffic. Considering that it’s over 30 years old, it feels as though it has a spring in its step once again. Brill!
