Does anyone have any information regarding the gear ratios in a superford gearbox? We have one on our car and would like to know what sort of overdrive ratio we are getting!
If it's the British Supaphord, built in Grays' Inn Road, London, then, according to P186 of 'The English Model T Ford Vol 2 - Beyond the Factory', its none-direct ratio will be one of the following:
CA or TA 0.81
CB or TB 0.73
CC or TC 0.66
CD or TD 1.24
CE or TE 1.37
CF or TF 1.53
The 'Cs' were for cars, the 'Ts' for TT
I think that the CD is a CA turned round etc.
