Dear God, that would be one quick A40, Paul, and discs would certainly be advisable. If you succeed, just remember the old Irish advice, "Never drive quicker than your guardian angel can fly!" Good luck with the conversion.

paul mate, yes a member of my local a30/35 group run an a40 with a fiat 2.0 twin cam and gear box he uses a ford rear end from a anglia 105e with midget front brakes as these are a easy swop, and he also has a morris minor with a fiat twin cam, all the go back in the day !!. early race cars were using a series engines and i think mid 60s lotus twin cams were being used i know of a few mk1s that run lotus twin cams, so in answer to your question YES it can be and as been done ive seen them fitted and their a reasonable amount of room left to service and work on them ;)
nearly forgot if you go ahead with this conversion please up load pictures that would be most grateful :)

There was one was for sale on E-bay a few years ago with a 131 2000cc twin cam. There was a post about it from Mike but the pictures have now been removed from listing.

Interesting prospect. Not something i'd do, as i swear by the A Series, and there's plenty of serious tuning mods for them, expensive mind. Ask me how i know........
For front discs it HAS to be Midget ones...........no mods required at all. Any other back axle would just need the spring mounts from the A40 one swapped over. And the width attending to. Good weldy weldy job required of course. There is the option of 1" larger drums for the rear, from a Riley 1.5/Wolseley 1500.......these are a direct bolt on, and the weaker half shafts are available in uprated form for the A40. This enables the original wheels to be kept, and become a sheep in wolfs wotsits.

you see, the fiat engine and gear box weigh nigh on half of the A series as it being an alloy construction, also the fiat engine has a cross flow head and twin cams power to weight and the A40 only weighing in at 785 kilos before removing the engine and box, but a good rear axle is needed (strong) ;)

Would the halfshafts need up-rating, Stoney?

yes half shafts need to be up to it, i understand that rae davis do such items, i under stand that a lot of the problems are that the shafts are only have one bearing that being at the wheel side its said that a bearing half way down the axle case would solve most of these problems,but at a cost, the easy way is either midget, wolseley 1.5, or a ford rear end as most cars did in the 60s-70s and there are lots of ratios to chose from, im sure that a lot of people will disagree with me but hey ho

A40 half shafts are unique to A40s. It's the length that's important. Midget ones are a little too short, so there's not enough of the splines in the diff. They'll work, but probably not for long.
