Greetings, I have acquired a partly rebuilt 2litre saloon (1950) without motor. So far I have not had any luck tracking down an AC engine for it in this country so I am contemplating powering it with a Zephyr motor. Has anybody done this and are there any difficulties? What about diff ratios? I work for a company that specialises in 5 speed gearbox conversions so making a bellhousing is not a problem but I also wonder whether I should replace the Moss box with a 5 speed and make a nice touring car out of it and disregard the originality aspect. We have recently made a conversion for a Ford powered Aceca in Australia. If possible I will do it in such a way that I can return it to original if the original motor turns up. Any input or suggestions welcome, Thanks, Ian.
