MG Midget and Sprite Technical - High Compression? - gear ratio?

I have a 1972 RWA Mk3 midget - how do you know what compression and gearbox ratio is fitted please.

Thanks
Dave Price

Dave should be high compression engine, Output was 65 hp (48 kW) at 6000 rpm and 72 lbf·ft (98 Nm) at 3000 rpm. However, this was a de-tuned version of the engine that was given to the Cooper S. The Midget retained the standard 12G940 cylinder head casting that was common to other BMC 1300 cars, whereas the Cooper S had a special head with an extra two bolts to fasten it to the cylinder block. Not sure on gearbox ratios..

the engine number has either an H or an L in the appropriate place for high / low compression. Don't understand your gearbox ratio question unless you think you might have a Morris 1000 box fitted?
